Having problems with your 2000 GMC Sierra ?
Transmission wont shift out of 2nd...tachometer and gas gauges shut off then battery light comes on and gauges go on. i have replaced the transmission
If you have the same problem as before replacement,the problem is not with the trans\012there may be an electrical problem messing with the trans computer\012I had an alarm system that was installed incorrectly and the the computer compensated by lock out\012This is a function where the trans will stay in second gear to prevent any further damage\012check the relay box under the hood carefully...look for a loose or damaged wire
