My truck maybe taking a poop on me but im not sure. 1988 chevy pick up . new jasper engine abd was running good untill yesterday i went out and all i had was reverse. The truck moves but it doesnt seem to be slipping real bad it almost seems like theres not enough vacuum . there was no warning for this. I changed the tranny filter and fluid last night and the fluid looked ok. but the pan had a little fibers in there. Any ideas what could cause this or does it seem like the tranny is toast? I didn hit a big Fn cat the night before but I centered up on that puppy and took it out square with my right front wheel:th_sinister: It was ok the rest of the night. The truck that is, The cat well you get the picture!
