Ah yes the crappy third into fourth. At this point I’m just driving mine until the tranny finally gives.Come to think of it, when my 10R80 (original one) was shifting poorly it made this louder than normal whistle (not just the usual shift whistle). Does yours slam 4th gear, have delayed engagement at times (i.e. going up hill the downshifts slip and lurch), and there’s a pause and then the noise?
If so, you’ve described my original 10R80 to a “t” minus the squealing of tires in R which was also a delayed / violent engagement issue.
My newly rebuilt unit does not make any noises nor squeal tires anymore.
