GM- TH400 Output shaft, 9"OAL, uses steel speedo gear SLIP YOKE U34678DA

# GM - Chevy - TH400 Output shaft, 9"OAL, bolt-on yoke, uses steel speedo gear U34678DA The TH400 automatic transmission with a 9-inch slip-on yoke style output shaft and steel speedometer gear was a common configuration for numerous General Motors (GM) cars and light-duty trucks from the mid-1960s to the 1970s. Vehicle Applications This specific TH400 variant (often with a 4-inch or 9-inch extension housing, which refers to the tailshaft length) was used in a wide array of vehicles where a durable, high-torque capacity transmission was needed. - Buick, Cadillac, and Oldsmobile: The transmission was first introduced in these brands in 1964 and 1965, respectively. It was used extensively in various models, often behind larger V8 engines. - Chevrolet Cars: It was a popular choice for many Chevrolet models, including full-size passenger cars and sports cars like the Corvette (specifically 1968-1977 models with the TH400). - GM Trucks and Vans: This configuration (slip yoke, mechanical/steel speedo gear) was widely used in heavier-duty 2WDChevy and GMC C/K series trucks and vans in the 1970s and 1980s. - Pontiac: Similar to other GM divisions, Pontiac used the TH400 in many of its V8-equipped cars. - Other Manufacturers: Due to its robust design, other manufacturers, including Rolls-Royce, Jaguar, and Jeep, also integrated the TH400 (or variants like the TH475 for heavy-duty applications) into some of their vehicles. The key identifiers (9-inch length, slip-on yoke, steel speedo gear) generally indicate a 2-wheel drive application from an era before electronic speedometers became standard. This shaft typically has 32 splines. * * * * * * **Guarantee & Return Policy:**   In any event a part does not live up to our customer's reasonable expectations, we will ship a replacement or issue a refund within one business day of receiving returned item.
