Rolls-Royce and Bentley Transmission Overhaul

The Transmission in the Rolls-Royce and Bentley cars based on a System from General Motors. They are called TH400 and TH350. A widely held belief is that they are identical, that is wrong. Most of the parts are identical but not the every thing. The anchor are not the same.

TH is the shortcut for Turbo-Hydramatic.

You can found more informations about the TH Family  on wikipedia US.

I will advise to study the book "Haynes TechBook - General Motors Automatic Transmission Overhaul" and the Workshop Manual from Bentley and Rolls-Royce.
