i just installed my rebuilt tranny out of my old car into the iroc..
now this one works great, except for at WOT when its shifting (1-2 and 2-3) it jumps around redline for a few seconds like its slipping... and when it finally does shift the rpms shoot up about 500rpm before they drop back down into the next gear...
this tranny was just recently rebuilt with transgo and only has a few thousand miles on it..
any idea what could be wrong???
