Since you brought this up, I'm having a similar problem with my tranny. It shifts easily up and down through all the gears, but after the car has been driven for a while and gets hot, it will briefly grind on a downshift to fourth gear only. No other gears, just downshifting to fourth unless I rev it a little to match the RPMs. Could this be that pesky plastic clutch line heating up? Thanks! payne #2975 > Hi all, > Since I am still new at owning a DeLorean I may havesome really dumb > questions.
