could this also be a broken vac line? im experiencing the same problems except it wont go in reverse it does the same neutral rev. but if i let it sit for say 4 minutes off and then try it again it, reverse and forward will work for like maybe 10-ish minutes and only in low gears. just after this winter storm but i noticed behind my battery there was a vac line completely anihilated im not sure if thats even relavent to the problem.

thanks
