How can you tell the difference between a TH350 and a TH400?
The TH-350 uses a square pan, with one corner cut off. The TH-400 uses an oblong-shaped pan with one side having a “hump” in the pan and one side is curved while the other two sides are straight. The TH-400 pan also has two circular indentations on the humped side of the pan.
How do I know if I have a Turbo 400 transmission?
It is identified easiest by its “375-THM” designation cast in the underside of the tail housing. The TH475 was an extra-heavy-duty version, and was found in larger trucks from 1971 on. If you are trying to determine the TH400 from another in a vehicle, a fast way to tell is to look at the kick down mechanism.
How do I identify a TH350 transmission?
Look for the vacuum modulator. It will be on the side of the transmission and have a rubber vacuum line attached to it. If this fitting is on the right front of the transmission, you have a TH350. On the similar TH400 it is attached at the right rear of the transmission.
Is a TH350 the same length as a TH400?
The TH350 with a 12″ tail is the same length as the TH400 with a 9″ tail. Even then, the crossmember mount is a different distance from the back of the block.
Is TH400 and Turbo 400 the same?
They are, for the most part, interchangeable on the same vehicles; however, you would normally find the TH400 in larger engine applications because they are able to function more reliably at higher engine rpms.
What transmission is best for racing?
In race cars, compared to a Powerglide a TH400 is better suited for cars with large tires and taller rearend gearing. Heavier cars need three speeds to help get them up and running. Another three-speed option is the TH350.

What is the difference between TH350 and TH400 Trans?
The difference is in their shapes and sizes. TH350 is smaller than TH400 and there are fewer moving parts inside of it, which makes it able to be fitted in a small or light vehicle. On the other hand, TH400 is heavier and stronger than TH350.
Is a TH400 a good transmission?
The TH400 or Turbo 400 is a good transmission that was used in several cars years ago. This popular transmission was found in GM’s cars, as well as, Rolls-Royces, Jeeps, Jaguars, Ferraris, etc. The TH400’s high-level of adoption could be tied to its remarkable features, and it proved that people can once again rely on GM transmissions.
What kind of transmission fluid goes in a TH400?
If you want to use your TH350 or TH400 for faster and speedier performance, perhaps Ford type F fluid is best for transmission purpose. I’d recommend Dexron III too, but Dex 3 is more of a friendly companion to TH350. For TH400, you have more torque pushing through a high profile engine.
