In the early 1950s various manufacturers without the resources to develop a proprietary automatic transmission bought Hydra-Matics from GM. The all cast-iron Hydramatic was the heaviest automatic transmission ever produced for automobiles. And the super-tuning of this unit ensures that you can improve its performance to be a ride worth taking on fast and hard spins.

The 4 cylinder models have 4 large cooling holes near the torque converter, while on the "bigger cars" there are no cooling holes. The front pump was a variable displacement vane unit driven from the fluid coupling housing, which meant oil pressure would be available immediately upon starting the engine. If the leak is minor, try Sort by. [3][4]. Usually, bands are applied by a servo and released by spring pressure, but in this case, the band was held off by the servo and applied by spring pressure (actually, when the engine was running, the band was applied by a combination of spring pressure assisted by oil pressure). *This transmission is part of a joint-venture between General Motors and Ford Motor Company to split development of two transmissions, a longitudinal 10-speed and transverse 9-speed. Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by both General Motors ' Cadillac and Oldsmobile divisions. concerns that are engine performance related. Make sure the shifter feels as though the gear ranges are correctly adjusted. This same group of engineers was then moved into the General Motors Research Laboratory, building pilot transmission units during 1935-36 which were then handed to Oldsmobile for testing. it. Also, the original Hydramatic required periodic band adjustments as a routine maintenance item that later versions did not. It also uses the same vacuum modulator as the Turbo 350. The rear unit ring gear hub had a small gear machined on its end which served as the reverse unit sun gear. Hydramatic, but GM called MANY of their later transmissions "Hydramatic". Fluid Diagnosis Transmission fluid, the life blood of any transmission, should be checked for proper level, but also evaluated for condition. There was no separate Park position as found with modern transmissions. Generally, gear or buzzing sounds may be caused by transmission gear failure or air in hydraulics, cooler line contact with body or frame, exhaust contacting body or The driveshaft could still turn to cause the reverse unit sun gear and attached rear unit ring gear to rotate at a very high speed, were it not for the fact that the rear unit ring gear band was now applied by a heavy spring. Coverage limited to defects in material and/or workmanship of the specific part only. There are two significant variations of the Turbo 400.

This was improved upon for all 1965 models with the "D L2 L1" or "D S L" quadrant, which allowed "dual range" flexibility as did the Dual-Range Hydramatic of 1953-1955. - Casting numbers on the case, extention housing and side cover The easiest method of GM automatic transmission identification is to examine the transmission pan. If the gear sound follows the transmission shifting (such as growls in first and second, but not third) then the transmission planetary may be at fault. gross weight.

If fluid is at Unlike the Turbo 350, instead of a kick down cable, it uses an electrical slide switch, which is controlled by the throttle linkage. A third variant was the light-duty rear wheel drive Turbo-Hydramatic 180 used in many European models. The reverse was obtained by applying torque from the front unit (band on, in reduction) through the fluid coupling to the rear unit sun gear. TempestTorque, ( Pontiac) a two speed based on Powerglide, but having the added feature of " Split Torque " dividing the engine power between mechanical connection and the torque converter in high gear. (Please note that GM later used the Check transmission fluid level. Relatively constant pressure was maintained by moving a slide inside the pump, which had the effect of changing the pump's displacement and therefore the volume of oil being delivered.
