The Controlled-Coupling Hydra-Matic used 3.97:1, 2.55:1, 1.55:1, and 1.00:1. Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by both General Motors' Cadillac and Oldsmobile divisions. The HydraMatic 350 transmission was prevalent in nearly all GM, rear-wheel-drive cars and trucks through 1984. Generally used in straight and V6 and small block engines. This modulator is stationed at the transmissions side, and there will be a vacuum line connected to it. 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. Some transmissions have a code stamped onto them. inspection, repair and reseal will be required. The result was a remarkably efficient level of power transfer at highway speeds, something that torque converter equipped automatics could not achieve without the benefit of a converter clutch. Classic Industries offers thousands of parts for GM transmissions and drivetrains. 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. Powerglide Transmission Turbo Hydra-Matic .

This number will contain division ID #, model year, assembly plant and production sequence (last 6 digits) of the VIN stamped onto the transmission. The TH350 (Turbo-Hydramatic) transmission identification, decoding, and super-tuning are what sets it apart from other transmissions. TH350 - Modulator is located at the back of the transmission case. Due to the manner in which the rear gear assembly was arranged, the coupling went from handling 100 percent of the engine torque to about 40 percent, with the balance being handled solely by the gear train. Even its successor, the Controlled-Coupling Hydramatic was reviled by shop mechanics having to remove or reinstall such a unit, as they, too, were quite heavy when compared to other contemporary units. Cars that used the TH350 transmission include those from the late 1960s, as well as some GM all rear-wheel-drive vehicles launched in 1984. You also have the option to opt-out of these cookies. Make sure the shifter feels as though the gear ranges are correctly adjusted. During 1934, the Cadillac transmission group had developed a step-ratio gearbox that would shift automatically under full torque. If the leak is minor, try It was a later version of GM's "dual-range Hydra-Matic", first introduced in some 1952 models. 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. Unfortunately, this makes transmission identification difficult to accomplish while the gearbox is installed in the vehicle. Can be tricky. The original Hydra-Matic continued to be used in light trucks and other commercial vehicles until 1962. On the THM700-R4 the VIN is either stamped onto a boss behind the bellhousing flange on the passenger side, just above the pan on the drivers side, or just behind the governor cover, stamped vertically where the case meets the tailshaft housing. The 700R4 transmission, also known as Turbo Hydra-Matic, is a 4-speed automatic transmission launched . Sales & Info: 330-434-5216 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). The THM200 and the THM250 have pans shaped like a THM350, HOWEVER, the THM200 will have the words HYDRAMATIC DIV. There is no leaking coming from the front seals, rear sears or oil pan. It is widely known as one of the best automatic transmissions ever built. On the contrary, the TH350C, a variant of the TH350 that has a lock-up torque converter had codes including MV4, MX2, MX3 & MX5.

Steel tag on the passenger side: Another long-standing driver complaint would be "flare" when trying to get a "3-2" downshift when going around a corner, which usually resulted in a neck-snapping jolt upon band application. 4L60 means 4 forward speeds, L = longitudily mounted (rear wheel drive). Controlled Coupling HydraMatic and Roto HydraMatic both have the "Split Torque feature" whereby, in high gear, the torque is divided 40% through the fluid coupling and 60% through mechanical connection, which made these transmissions more efficient than any other automatics before the lock-up torque converter was used. You can then lower the car onto the stands. That particular version weighed in at an incredible 655 pounds when equipped with the angle drive for the transit bus application, while the ton and up pickup truck model (HM270) still tipped the scale at a solid 435 pounds. At higher speeds, the rear pump provided all the oil volume that was needed to operate the transmission and the front pump's slide was nearly centered, causing that pump to produce little output. Fluid level should be at correct range hot, be free of bubbles on the dip stick, and not be excessively dark, watery or appear I live in Covington, Tennessee and I just had my Monster Transmission installed in my 2001 Dodge Ram and I'm completely happy with it. GM produced many transmission variants over the years, we included some of them here, but our main focus is identifying the fluid pans for Powerglide, Turbo 350, and Turbo 400.
