it has a lot of upgrades in it. it has to be something mechanical that let go prematurely. if i put it in low it doesnt want to go either. that is when the low reverse and forward gears and all are in one. and no reverse. it will haul ass in drive. just something little im sure but it does have discolored fluid. so i am sure that the rear clutch pack is toast as well. i think i will have joe softne the 1-2 shifts and do a few other things while she is apart.
