4 speed manual transmission for chevyThrough the 1950s, all makers were working on their own automatic transmission, with four more developed inside GM alone. All of GM's early automatic transmissions were replaced by variants of the Turbo-Hydramatic by the 1970s.Manually shifted on Column. ) The basic rear-wheel drive Turbo-Hydramatic spawned two front-wheel drive variants, the transverse Turbo-Hydramatic 125, and the longitudinal Turbo-Hydramatic 425. A third variant was the light-duty rear wheel drive Turbo-Hydramatic 180 used in many European models.Also manufactured and used by Holden as the Trimatic transmission. Ford led the design of the 10-speed transmission, as well as filing the design patents for said transmission. According to an official report by the SAE (Society of Automotive Engineers) the design of the 10-speed gearbox is essentially all Ford, while GM was responsible for designing the 9-speed 9T transverse automatic gearbox. As part of their joint-venture, Ford will let GM use the 10-speed transmission with rights to modify and manufacture it for their own applications.Retrieved 2019-07-16. Retrieved 2019-07-16.

Some had specific uses, so you can narrow it down to a shortlist based on the vehicle make and model. It’s helpful to begin with the basics to make it easier to understand. What Does the Transmission Do. There are three types of transmissions or gearboxes that you’ll see in order from first to latest technologies: Manual Automatic Continuously variable transmission (CVT) Its primary purpose is to create a balance between speed and torque, or the power needed to move a vehicle forward. The differences between the types speak to the ways that it occurs. The engine and the wheels operate at different speeds, with the former turning at faster rotations per minute (RPM) than the wheels.http://www.pyatnishko.kz/userfiles/bosch-maxx-1000-washing-machine-manual.xml

When you turn on your vehicle, it’ll need to draw on a lot of power to get it moving. A higher torque, therefore, is necessary. On the other end of the spectrum, you don’t need as much power output when you’re driving on the expressway, hence, the need for balance. A manual transmission is an enclosed box consisting of different sized gears, rods, meshes, shafts, cogs, and other parts, all encased in oil to keep things running smoothly. The gear ratio describes the relationship between the different components. Each gear represents a varying combination of them that, in turn, produce a specific power-speed output. It’s not unlike what you’d see on a bicycle. The first stick-shift vehicles had three-speed transmissions and lasted up until the 1960s. As the technology caught up, the industry moved toward four-speed ones. There’s no denying how fun a car with a stick shift is to cruise on the highway whether it’s a Chevy Corvette or a Ford Mustang. It puts you closer to the road and the driving experience. That brings the discussion to the Chevy 4 speed manual transmission identification. Both the outside and the inside provide vital clues to determining what kind you have, beginning with the brand. Types of Manual Transmissions GM has since moved on to different technologies. The four-speed is a relic of the past with innovation pushing the bounds to nine- and even ten-speed gearboxes. Each of the 13 four-speed manual transmissions had a specific application. That of itself is the first step toward a positive ID. Right away, you’ve narrowed the field. The run-of-the-mill vehicle probably has either the Borg-Warner or Saginaw. Muncie, on the other hand, is a different animal. It’s one that you’re more likely to find in high-duty or performance rides. The automaker used some models only on certain types of vehicles. So, if you have a car, the chances are you won’t find one meant for a truck under the hood.http://carcompanyofcanada.com/fck_upload/bosch-maxx-1200-instruction-manual.xml They also used different ones for certain years, the term referring to the date of the model and not a calendar date. Steps to Identifying a Four-Speed Manual Transmission The first step toward a positive ID is to figure out what is the brand of the part. Fortunately, that task is easier than it sounds. Each of the top makes has a distinct shape. The entire transmission has a main case, side cover, and extension housing. The general form is the main box with a telescoping tube attached at the other end. Shape and Parts Borg-Warner is the most clear-cut. It has box portion has a straight end. The other part has a gradual narrowing with an abrupt smaller finish. The Saginaw is not as wide. The end of the case appears rounded with at least two visible protrusions. Finally, the Muncie falls somewhere in between. It is boxy like the Borg-Warner but with a slight curve. It also has two bumps along the edge. The telltale difference between the Borg-Warner and the other two is the number of bolts on the side cover. It has nine, whereas the Saginaw and Muncie have seven. You can tell the two apart by looking for the reverse lever. On the former, it’s on the side cover. On the latter, you’ll find it on the extension housing. Other parts to examine include the selector arms, noting how it’s attached to the main unit. Model Specifics Each model within the make’s line typically has slight variations that can pinpoint a range or maybe even a specific year. The Borg-Warner T10, for example, has a long run in cars between 1957-1988 and a brief one between 1968-1970 in vans. The T4 and T4C also had short spans. The T4 was only between 1983-1984 in cars and 1985-1987 in trucks. The TC4 lasted for 1982-1984. Sometimes, you can home in on the details by knowing the make and model of the vehicle in which it was found. The Saginaw manual transmission existed in cars from 1966-1984. However, it only stuck around between 1985-1986 in the Astro and Safari.https://www.informaquiz.it/petrgenis1604790/status/flotaganis17032022-1413 On a side note, neither vehicle made a go of it either, with both going out of production too. A similar tale exists with the Muncie. It is the youngest of the three. The M21 and M22 led things off for cars in 1963 going until 1974. The SM420 followed by the SM465 in 1968 held up the reins for the truck side until it ended in 1991. Materials The materials also vary with the make. Look at the construction. If the cover and case are cast-iron, it’s a Saginaw. If it has an aluminum cover, you’re looking at a Borg-Warner. However, some earlier versions had a cast-iron cover instead before making the switch to more weather-resistant materials. An all-aluminum transmission is a Muncie. If the four-speed manual transmission is a barn-find, the latter is probably still in decent shape. The others, not so much. It might be a good time to start checking out new truck prices. Casting Number All of the main parts of the transmission have a casting number that identifies the part and provides clues about when it was made. It is a physical trait, being within the mold. However, any vehicle manufacturer may tweak their designs. If an original one is modified, the casting number changes too. It is not interchangeable with the part number. It’s not unusual to find different casting numbers covered by the same part number. It’s the nature of the industry to change materials or refine a design. One thing that you can count on is that the casting numbers will get higher with each consecutive year. In other words, it’s newer. You may also notice the words, “PAT. PEND.” or “US PATENT NO” on a part which means, patent-pending or the official number, respectively. You can do a search on the US Patent and Trademark Office to home in on its date. It can identify the make too since the details of your search will include this info. The models of the Borg-Warner are T10, T4, and T4C. The last one was for trucks only. The casting numbers for the first one are either 13-04 or T10-XX.https://diatecgroup.com/images/4-speed-manual-transmission-for-chevy-truck.pdf The second are 13-51 or 13-52. Finally, the last one is 13-53. Saginaw has one type of four-speed manual transmission, making the identification quicker after figuring out the make. The Muncie includes M20, M21, and M22. The distinction is the ratio with wide, close, and heavy-duty close, respectively. IDing the transmission requires a look inside of the case. You will need to count things like the splines or teeth of the gears. Noting its location in situ can also identify the variation. The M22 or so-called Rock Crusher usually partnered up with big-block engines. Serial Number The serial number is where the money shot lies. It offers a lot of information to complete the story of the four-speed manual transmission. This figure is usually stamped and not a part of the mold. It’s also easily faked if you have concerns about whether it’s genuine or not. They often include a code for the date for helping you authenticate it. However, it’s not always as easy to decipher as it sounds. Auto manufacturers often use unique codes even for something as mundane as a month name. Muncie is a perfect example. Muncie Serial Number The serial number begins with a P followed by the month and day. The letter denotes the plant in which the manual transmission was assembled. So, P0201 means February 1. They didn’t add the year until after 1966. But wait. It gets better. Instead of a simple number to designate the month, the manufacturer went to letters with A for January and so on. Unfortunately, that wasn’t the case. What you’ll see for the ones after May is as follows: H for June K for July M for August P for September R for October S for November T for December There is also another number to denote the particular ratio. A stands for M20, B for M21, and C for M22. To decode it, you’ll need these bits of information. For example, a Muncie with P4H15A translates to a Muncie M20 assembled on June 15, 1974. Presumably, abbreviating it with this serial number gives a compact stamp that saves time and space. Identifying the Rest of the Transmission Bear in mind that some transmissions may contain a hodge-podge of parts. You may think you have one brand. But, when you look inside, your so-called matching-numbers parts isn’t what it seems. That’s what makes knowing a vehicle’s history essential if it’s from an existing car or truck. You’re more likely to find a Saginaw or Borg-Warner intact and not necessarily rebuilt since the automaker used them on everyday models. The Muncie is the one that you need to check. Since it’s a performance part, it’s in high demand among collectors. Earlier versions may have components of later ones simply because the transmission and its housing were better made later in its production. Chevy 4 speed manual transmission identification isn’t difficult if you know what to look for in the part. Luckily, the makes are different enough to give you at least a starting point. Though the serial number convention is sometimes confusing, there is a method in the madness that makes knowing which one you have an easier task. Looking at the shape, materials, and structure of the main case, extension housing, and cover are excellent places to start in your search for a positive ID. The other information will help you get to its production date to begin the quest for its story. Each transmission kit is engineered with factory-matched torque capacity ratings, helping ensure the transmission you purchase will stand up to the power of your engine.

Saginaw and Borg Warner models are normally used on general purpose applications. Muncie transmissions are known for both high-performance and heavy-duty applications, with three different variations available: the M20, M21 and M22. Identification begins by visually identifying the units as Saginaw, Muncie or Borg Warner models and then by differentiating the three Muncie units visually and by decoding the serial number. Step 1 Inspect the transmission. Both Muncie and Saginaw transmissions have 7-bolt side covers, while the Borg Warner has a nine-bolt side cover, according to Year One.com. Also, the reverse lever on the Muncie units is mounted in the extension housing, while the Saginaw reverse lever is mounted in the side cover Step 2 Locate the serial number to differentiate 1969 and up Muncie transmissions. The transmission case has various codes including the casting code and the serial number. The serial number provides the date of manufacture, however, on 1969 and later transmissions there is a letter code at the end which identifies the gear-ratio, which is different on all three Muncie models. The Letters F, G, I, L, N,O and Q are omitted. Identify Muncie 1963 to 1967 transmissions. These Muncies have the same serial number format, minus the gear ratio designation, so a spline and gear tooth count must be done. According to Nasty Z28.com, 1963 to 1965 M 20 transmissions have 10 splines and 24 input gear teeth, while 1966 and 1967 models have 10 splines and 21 input gear teeth. Tips The input shaft runs from the transmission to the engine and is part of the transmission. The splines are on the shaft going into the engine and the input gear goes into the transmission. This is illustrated at the top of the Year One Tech page, while the input gears are illustrated at the bottom (see Reference 2). Since the Muncie M 22 is a heavy-duty transmission, it is usually paired with high-torque big block engines and trucks.

It has a granny low and so then just 3 normally usable ratios. See Final Drive Ratios and notice the extreme benefit there is to gear-splitting by using the GEAR VENDORS. You will climb hills, cruise, tow, do everything so much better with the Gear Vendors installed. A true 7 speed application. There is just no good reason to drive a Muncie Sm465 equipped vehicle without a Gear Vendors. 5-Speed Manuals Look at the Final Drive Ratio charts and notice the great benefit in gear-splitting with the GEAR VENDORS.This will keep your transmission temperature as much as a 100 degrees cooler (extending transmission life) and puts the stress on the GEAR VENDORS planetary gearing which is much stronger than 5th. When you are running empty, 5th-over (double overdrive) will net you better fuel mileage and far less engine wear at today’s 75mph speed limits. Even the resale value of your truck will improve by more than the cost of the GEAR VENDORS because you will be able to point out that the engine has seen better care and effectively far less miles than other used trucks. These words are very similar for the M20 and T10 but with some slight ratio differences depending on model. Overdrive is the first reason you are going to add the Gear Vendors. 28.6 faster cruising speeds than you have now. Your 4.10 gears will cruise like 3.20s and your 3.55 will cruise like 2.77s. If you are normally aspirated expect 28 better fuel economy. If you have forced induction expect 50 better mpg. Performance is what the Gear Vendors is all about. This product is a very high-tech planetary overdrive. With our Auto-Launch circuit on you will leave the line in 1st and as the engine gains revs it will automatically shift clutchless to 1st-overdrive. This means you are 28 farther down the track or street before you have to clutch the car. This is key to acceleration as otherwise any manual trans car gives up big hunks of time to an automatic on the 1-2shift. Gear Vendors 1st-over ratio is only 7 hundredths different than having shifted to 2nd (not discernable and actually closer in ratio). It is just 1st-over where you can use this clutchless shift. You can be in 2nd just boulevard cruising and show off by stepping on the throttle and hitting the Gear Vendors button on your sifter for 2nd-over which is identical (exact same ratio) as having shifted to 3rd but only clutchless (and with a nice bark of the tires). Most street guys will just grab a clutchless gear at whatever moment they start accelerating and then progress up through the gear box leaving the overdrive on so that each gear is just now up a step. The bracket racers and serious street guys will flip the 3-4 side cover lever over so they can easily have two clutchless shifts in the A? mile with just one clutch depression. Flipping the 3-4 cover lever over lets them grab with a straight pull back because it moves 3rd to the 4th gear position on the pattern. Just awesome performance gains greater than a full second on the watch, increased mph and far more performance than any 5spd or 6spd tranny swap. So you get a 5th gear overdrive and at least one clutchless shift to be used at any moment (we ship the kit with our 6speed car badges) and a huge performance gain plus get to retain your period correct transmission in the car and get the worlds strongest overdrive trans. Since your Muncie or BorgWarner is stronger than any non-race 5 or 6 speed, the Gear Vendors is just he right way to get overdrive in your GM manual performance car. The Gear Vendors comes with a 30 day money back guarantee so you know you will be happy with everything you get from us and how it installs and drives. If you take a few moments to study the gear chart for your transmission and rear end ratio combination you will se why this product is so popular. The Final Drive Ratio shows you how many times the engine turns for one complete turn of the tires. Gears are multiplier of torque. Close ratio gearing lets us work both the torque and rpm side of this equation for big gains in HP and performance. Same with 2nd-over compared to 3rd. Of course, with gear-splitting we are keeping the engine rpm up from one shift to the next and further exploiting the ratio benefit. Check tail length and yoke to confirm. We offer quality rebuilt manual transmission, parts and rebuild parts kits that are designed to be top of the line. After locating correct unit a link is supplied to provide detailed information on specific kit and parts that are available for your unit.
