Roto Hydramatic (sometimes spelled Roto Hydra-Matic or Roto-Hydramatic) was an automatic transmission built by General Motors and used in some Oldsmobile, Pontiac and Holden models between 1961 and 1965. It was typically paired with Small Block V6 & V8 engines. Prior to 1967, transmission ID numbers contained the plant prefix code, month and date of production (expressed numerically), and a shift code (D = Day, N = Night). Transmissions have RPO numbers, usually beginning with "M". Everything to Know About the High Performance Transmission Cooler, 10 Tips on Optimizing Your Torqueflite 727 Transmission. Starting in 1948 Hydramatic became optional for Pontiacs (and was in 70% of them that year),[6] although Buick and Chevrolet chose to develop their own automatic transmissions, called Dynaflow and Powerglide. The 400 transmission has a main case of cast-aluminum alloy with a length of 24-3/8-inches long. Pre-67 Example: C213N - (C = Cleveland Powerglide, February 13, Night Shift) TH400 - Modulator is located on the side of the transmission case. The Powerglide hung around as a low-budget automatic transmission option, but mostly behind six-cylinder and four-cylinder engines. For example, replacing a Powerglide with a Turbo 350 is an easy swap. The shape of the main housing will give a reasonably reliable indication of the transmission group to which your gearbox belongs. Email: [emailprotected] Always begin ALL transmission diagnosis with the following initial steps: Transmission fluid, the life blood of any transmission, should be checked for proper level, but also evaluated for condition. frame, or an engine problem. The 1956 through 1962 Corvettes only used the aluminum versions. Summershandy Ford didnt offer its automatic transmission until 1951, and Mopar buyers had to wait until 1954. MX3 Another Turbo 350 C code. Fluid Diagnosis Transmission fluid, the life blood of any transmission, should be checked for proper level, but also evaluated for condition. Responding to market demand for a three-speed automatic, The Turbo-Hydramatic 350 was introduced in 1969 as a replacement to the Powerglide in Chevrolet cars and trucks with six-cylinder engines or low-horsepower V8 engines. These bearings can be used at the front planetary pinion carrier as well as the rear planetary ring gear. See partial VIN stamped on housing as well as the date code on the fluid pan. A plugged vacuum manifold port may also cause the issue. The transmission would have four forward speeds (3.82:1, 2.63:1, 1.45:1, and 1.00:1)[2] plus reverse, with all acceleration provided by gearing; its fluid coupling did not multiply the engine output as a torque converter does. 4L80 - An overdrive model of the THM400. Not only is the diagram below helpful for identification purposes, but is a great visual source to see if you have enough room for a swap you might be contemplating. The TH350 transmission is 21-3/4 long and its body is made of aluminum alloy. Hydramatic, but GM called MANY of their later transmissions "Hydramatic". On the Turbo 350, the VIN will be stamped on either the drivers side housing (near the shifter), on the right side of the housing just above the pan, or on a boss behind the bell housing flange on the passenger side of the transmission. Description Specification Hydramatic 1949-1955 Special Instructions: 1946-1956 Hydramatic units can be identified by two pans on the bottom and a side pan. And given that this is a transmission that has stood the test of time, its rebuild will yield even more impressive results. While there are no distinctive pans and bolt counts to make transmission identification simple, 4-speed manual transmissions can be generally identified by examining the side profile. engine. Located in Huntington Beach, California, Classic Industries has provided over 1,000,000 customers with parts and accessories they've needed to restore their vehicles for over four decades. The 4L80E would be the "electronic" model. Almost 200,000 had been sold by the time passenger car production was halted for wartime production in February 1942. WE ARE READY TO SUPPORT YOUMon - Fri 9:00am - 6:00pm EST. Drive should engage drive, reverse should engage reverse, and the shifter should be free to move.

Therefore, work with us lets show you all you need to know about this unit. If the leak is major (such as front pump seal) or the leaks are too numerous, then a complete internal This cookie is set by GDPR Cookie Consent plugin. The constants in decoding the trans ID number are the date the transmission was produced. 1976 through 1981 model years. Ensure the engine is running correctly. The output shaft was machined onto the rear unit and reverse unit planet carriers. The length of the unit can also tell you a few things. During the 1930s, automakers sought to reduce or eliminate the need to shift gears. the shift since the vacuum signal to the transmission may be wide open throttle. This greatly reduced slippage, which was audible by the substantial reduction that occurred in the engine RPM when the shift occurred. They created a standardized naming system across the product line and changed the name of the Turbo 400 to 3L80. Evolutionary designs came with unique pan shapes, which are clear indicators of which transmission you are dealing with. Unfortunately, this makes transmission identification difficult to accomplish while the gearbox is installed in the vehicle. So, whether you are heading out to check out a "For Sale" ad that could be your next project or trying to make heads or tails of a junkyard find, the following charts can be useful guides when it comes to GM transmission identification. That is, the input torus of the fluid coupling ran at a slower speed than the engine, due to the reduction of the forward gear assembly. The 700R4 transmission, also known as Turbo Hydra-Matic, is a 4-speed automatic transmission launched . This measurement should be taken from the front and from where it bolts to the back of the engine to the transmissions end that links the tailshaft housing. 4L60 - Early 1990's saw the 700R4 renamed to the 4L60, and "electronic" models were named 4L60E. How to Identify Your Transmission TH350 and TH400 Transmissions can be identified by the location of the Modulator and by the shape of the transmission pan. On the THM350, the VIN will be stamped on either the drivers side housing near the shifter, on the right side of the housing just above the pan, or on a boss behind the bellhousing flange on the passenger side of the transmission. Are the other numbers date of assembly or something? 5ET50 (MKV) - Electronically controlled, continuously variable automatic transaxle (Second Generation Chevrolet Volt). In 1940, the Hydra-Matic was a US$57.00 option ($1,102 in 2021 dollars [4]),[3] rising to US$100.00 ($1,842 in 2021 dollars [4]) for 1941. THM250 - Used in small 4 cylinder cars (Vega, Sunbird, Monza) from 1973 to 1981 and some Nova/Camaro/Chevelle 6 cylinders in 1974 & 75. When the transmission upshifted to second gear, the forward gear assembly locked and the input torus now ran at engine speed. Pontiac Cadillac, Hudson, International, Nash, Kaiser and Lincoln models. On the other hand, theres no need to measure the tailshaft housing and this is an adapter with a cone-shape design. Never underestimate the mighty post-war Powerglide. The HydraMatic was designed to combine the hydraulic operation of a planetary gearbox (allowing much shifting to be automated) with a fluid coupling instead of a friction clutch, eliminating the need for de-clutching. When it comes to transmissions, no other company provides this level of commitment to their clients. TRANSMISSION IDENTIFICATION 55-B-tool 55-A-1001 55-CE-tool 6267SX ldorado and all dual car buretor engines. The heaviest of them all was the Truck Hydra-Matic version offered by GM Truck and Coach Division in its line of light- and medium-duty trucks and conventional buses, as well as with its transverse-mounted gas L6 engined transit buses produced until 1963. Some basic shift diagnosis include: Leaks may be minor or severe. Rebates may be submitted over two invoices within 120 days of each other. Other than the shape of the fluid pan, another key way to identify the Turbo 350 is by the vacuum modulator. Modern 6-speeds are easy to spot, and 5-speeds are not difficult either, but when it comes to older 4-speeds and automatics, the increased variety can muddy the waters. 2004, 2005, 2009, 2012, 2015, 2016, 2017, 2019 Charlie Tranny. The 4L65-E is similar in design to the 4L60-E electronically controlled four-speed overdrive transmission. Typical Turbo 350 fluid pan.

It was subsequently replaced in that role by Chevrolet Division's Powerglide (where it was dubbed "Pow-R-Flow") in the GMC light truck line, and later, in 1966, with the Turbo Hydra-Matic (THM) in GMC light trucks, whose simplified design was much less costly to manufacture. Will Not Move Any Gear If it will not move in any gear, then a major failure may have occurred. During 1934, the Cadillac transmission group had developed a step-ratio gearbox that would shift automatically under full torque. Theres a cable that may be connected to the transmissions side and next to the location of the shifter linkage. Because the rear unit band was not applied for reverse, the rear unit and reverse unit compounded causing the combined planet carriers to rotate opposite to the input torque and at a further reduced speed. Front = 1/3@Reverse = 1/3@. (Standard and Dual Range). Check out our GM transmission parts store page, or click the button below to get a free full-color parts catalog.

All Oldsmobiles installed with the Hydramatic had at the bottom edge of the front fender directly behind the front wheel a badge that said "Futuramic" which identified an Oldsmobile approach to simplified driving, and the presence of an automatic transmission. Transmisson Tech Info & Product Instructions. The result, dubbed "Hydra-Matic Drive," went into production in May 1939 for the 1940 model year. Others have a tag rivited to the case. This was a cast iron cased, hydraulically controlled The extensive wartime service greatly improved the postwar engineering of the transmission, later advertised as "battle-tested.". During the war, the Hydramatic was used in a variety of military vehicles, including the M5 Stuart tank (where two of them were mated to twin Cadillac V8 engines) and the M24 Chaffee light tank. Introduced in 1939 for the 1940 model year vehicles, the Hydramatic was the first mass-produced fully-automatic transmission developed for passenger automobile use. The Roto eliminated the front fluid coupling that was used in the Controlled coupling Hydramatic and the connection between the engine and transmission was made by using the small fluid coupling that is used also to control the front planetary gear set' (in which the "dump and fill" shifting principle was retained from the older controlled coupling Hydramatic).
