While both concepts explain the level of acceleration attained by a vehicle, the horsepower entails the total power output of the engine which is dependent on the torque and rpm. Over the years, a lot of people have misplaced the concept of horsepower and torque with each other. Th400 stands as a preferred choice for high-performance cars, matching the need for an efficient power/energy transfer. While the planetary gearset system looks a bit more complex, it is less efficient compared to the Th400 gear set. Th350 has the reverse-cut planetary gearset, while Th400 has a forward-cut spiral gearset. The gearset might not act as a noticeable difference between Th350 vs Th400, but it greatly determines the efficiency of both systems. difference between th350 and th400 (5 key Differences) 1. This makes it more energy-efficient, provides better performance, and achieves efficient power transfer. Th400 transmission uses a forward-cut spiral gearset. While the Th350 transmission uses a reverse-cut planetary gearset, the

However, this thick frame is exclusively designed to handle heavy-duty vehicles. The built quality and design of TH400 made it strong enough to handle 4WD vehicles.īeing made from aluminum and iron construction, users have the assurance of durability and the ability to withstand heavy usage. The three-speed automatic transmission also featured three tail shaft lengths. With the rollout of different versions, they became the best choice for a transmission that can function at higher RPM and engine power. Released in 1964 with the model name “Turbo Hydra-Matic”, it was specifically used for Cadillac and Buick. Th400 transmission is a heavy-duty transmission. Th350 is the right choice if you need a transmission with less weight, cost-effective price, and can fit into smaller vehicles. This is slightly lower compared to TH400 that can handle as high as 650 Hp with a high-torque transmission. The Th350 has an aluminum alloy case and steel gears.Īlthough, it has a performance level that can handle up to 500 Horsepower (HP), yet it has a low torque transmission. This is because the construction is solely on lighter materials. This transmission boasts a lighter frame. This was not just because of its compactness, but also its adaptability and compatibility. TH350 became a household name for jeeps, trucks, and most rear-wheel-drive cars. However, the TH350 was always known for its strength, size, and ability to fit into smaller vehicles. The duo named the transmission after themselves Chevy-Buick Combined (CBC) transmission. As a joint project, Chevy and Buick developed the TH350 as the successor of the GM Powerglide automatic transmission.

The TH350 transmission is a 1969-released three-speed automatic shift transmission. The vacuum Modulator is at the back of the right-hand side of the transmission The Vacuum modulator is in front of the right-hand side of the transmission.
