1986 CM clutch, pp, t-bearing, p-bearing, shifter busings...shifting into 2nd and 3rd fast/hard results in grinding. 1st gear...doing say 5-10 mph and then push clutch in, here a brief grind from tranny. 2nd gear pulling to like 5k tranny makes a grind/whir noise. Transmission going to crap....i know the 2nd 3rd syncrhose must be crap. And almost always, when going into reverse, it will give a little grind. at stop light..i reved it to 1500 because i was listening for a sound i thought my motor was making, but turned out to be another car...and i pused in clutch and put in gear when revs were dropping for 1500...grind...that cant be shouldnt matter if you were at 6k and put clutch in and tried going into 1st or would it?

Last...good idea to try and get my trans rebuit, or find a j-yarder......miata gears w/rebuild?
