hey when did they stop making the 700R4 and start making the 3L60E for the T/A

 

it's a 4l60E.

The 700r4/4l60/4l60e are essentially all the same transmission. Hard parts are interchangeable. the 700-r4/4l60 was offered up until 93. It was hydrallically (sp) controlled, and the 4l60-e that came in 94 was electronically controlled.
