I have a 69 Firebird. I finally got it 99% done and running after 4 or 5 years of restoring it. Shifts nice through all the gears when engine not running but will not shift at all while engine is running. Everything is new or rebuilt. I am running a Muncie M20 and a Hurst shifter with a Ram 201 clutch, Ram 401 pressure plate and a Ram 488 throwout bearing. I have had the transmission off and swapped out throwout bearings several times. Most recently was today where out of paranoia and having really nothing to lose at this point, I took everything completely apart to make sure that the clutch disk was facing the right way (it was). Put everything back together and still have the same problems. I am beyond frustrated. Was hoping to drive this car for the first time ever before winter. I am stumped and really need some help. Thanks in advance..
