Is the tranny in a 1997 GMC Sierra compatible w/ a 1998 Sierra with same engine, configuration, etc?

The links lead me to believe there are interchangeable. In fact this page confirms the compatible models

  Chevrolet Suburban (GMT400; 1993-1999) fuses and relays

Check the easy first
A) tranny fluid, with the vehicle running
B) all fuses
C) vehicle grounds for corrosion.
D) make sure the main tran's plug isn't pulled out at all. Even the slightest movement of the plug can cause it to go in limp mode which won't let you get out of 1st gear.

I believe it will be lack of fluid, or solenoid failure since you don't have reverse. Limp it to a tranny shop if you have any doubt. They may charge you to diagnose or not if its a simple fix. Either way if you don't do it proper you may be taking it to them anyway for a rebuild or new tranny.

I would get a used transmission with a warranty.

is it slipping? It may be the band's if you got a used transmission. good luck to you.

tranny bad

Ceheck all fuses in cab and engine compartment and make sure all harnesses on tranni are not corroided and plugged in tight.

IF BOTH TRANS ARE THE SAME,THEN YOU SHOULD HAVE NO PROBLEM

check the sensor on the transmission and give these guys a call at Schram auto and truck parts 1-800-292-1032 they sell only GM parts or try online at www.schramauto.com

I have the same problem with my 97.... especially shifting from 3rd to O/D... I've had the tranny serviced and flushed.... It still does it until the tranny warms up.... the tranny's in them are temperature picky!!!!! It's the nature of the beast!!! Wait until spring and everything will be good until next winter!!! If you're really concerned with it you can put a "cold front" on it or block half (NO MORE THAN HALF) of the tranny cooler with cardboard thru the winter months
