Lo/reverse clutch worn, internal fluid leak in clutch apply circuit, let a trans. tech check it out but prob. no easy or external fix, worth a look though. Good luck!

Good start point. I had no clue. Thank You for the info.

There are a couple of tricks that might work but you need a transmission mechanic to check it not a trans. chain store. Most places just want to swap it out, may need that but it is worth a look first!

Thanks again. I know an independent trans. mech. that can look at it next week.
