1994 Chev z-71 5.7 4x4 auto. What trans and gears do I have. Thanks

is the tranny a 3 speed or 3 speed with OD?? i dont believe they switched to the 4l60e tranny in 94. should be a 700r4 if it has the OD, which i imagine it does.

cannot tell you what gears you have but this info can be found on the tag found on the rear differential or on the RPO code sticker located in the truck.

4l60e but maybe not 3:42's. Look in your glove box. See if you can still read the rpo numbers. Look for the 3 digit code or codes starting with G. There may be more than one.
Post up what you have and we can tell you for sure.
Also look for HC4 or HC5
