94 K1500 shift trouble
Hey new to this forum, but I have a question. I have a 94 K1500 blazer, it wont shift into 2nd gear at all. When I put the truck in drive and take off I need to give it some gas get to about 20mph let off the gas and hit it again to make the truck shift but it goes directly to 3rd gear. If I take off with the truck in 2nd gear it wont upshift at all it stays in 1st. I have 1st 3rd and 4th gear no slipping and the tranny fluid isnt burnt. I also have no check engine light, it could be burnt out I don't know. But could this problem be the result of a bad shift solenoid or speed sensor? Its a 4L60-E trans.
