I have a 98 gmc Sierra z71. Had the tranny rebuilt a
lil over a year ago. I left work the other day and it
wouldn't shift outta 2nd. I can ease down my rd
and it shifts fine but when you get on the gas it
slips or when you get up to about 45 mph it slips.
What could cause this issue
Slipping is usually due to heat and worn clutches inside the transmission. Time to have the trans shop diagnose the problem. too bad your past the year warranty.
