This is the training manual from the Lincoln Technical Institute for Automatic transmissions. I am not sure of the year, but I am guessing 60's. It is from a previous student, so it has some pages of notes, prior to each section, and possibly some note written throughout. it is dirty from being in the shop while being used, but the pages are tight, and legible. It covers models of transmissions such as Detroit Pipeline, Jetaway, Torqueflite, Tempest, Corvair Powerglide, Powerflite, and others. Pleas look at the pictures and feel free to ask questions. It is heavy and is about 4" thick.
