HELP!!!!
HELP!!!!! Just had my transmission rebuilt on my 04
chevy Colorado 4x4. and it's already acting weird.
When I first start driving it and it's cold,it runs great.
But I've noticed that the temperature is rising above
a quarter and once it does,the transmission starts
acting weird. I'll be going 70mph at2,500 rpms,and
all of a sudden the truck downshifts a gear,raising
the rpms to 3500,and stays there. It doesn't shift
back to the higher gear. The temp then rises to
almost half. After I get off the freeway,and come to
a stop,then go again,it shifts hard from 1st to 2nd.
Any ideas would be amazingly helpful!!!
