View Full Version : 1-2 upshift very harsh

My 95 SC arrived this morning.

I noticed right away that the trans upshift from 1-2 is extremely harsh, like twist the half shafts harsh. Car got a new battery just before they shipped it. Is it possible the ECU didn't relearn correctly. 67000 miles and no records. Not sure if 60000 miles trans flush was done.

Could be a broken spring for the 1-2 accumulator piston. Any mention of a shift kit or J-Mod done to the tranny?
