2000 GMC Sierra won't go past 20 mph

Asked by Mar 02, 2016 at 11:08 AM about the 2000 GMC Sierra 1500 SL 4WD Standard Cab Stepside SB

Question type: Maintenance & Repair

My boyfriend had gotten my 2000 GMC SIERRA
stuck in snow and after we had gotten it out I
noticed it wasn't shifting right, wouldn't go past 20-
25 MPH but my RPMs would go high.. What can
cause this? Do I need a new transmission? Help
please!

Sounds like he burnt the trany up, or the exhaust is crushed.

Best Answer Mark helpful

Doesn't have exhaust on it at the moment, was falling off so was taken off to be replaced then this happened.

If he wasn't easy with the gas pedal when it was stuck, trany probably needs to be rebuilt.
