I recently bought a 91 C3500, and was wondering if my transmission would be a 4L80 or a 700R4. I have always had manual shift trucks, and this auto tranny stuff is greek to me. Thanks!

Thanks for the info! Mike L. 09-07-2005, 11:32 PM Yes, its a 4 speed. Thanks for the info! You got one of the very first ones. | ||
