Came in for slipd in third.We overhaul....could not find any problems so replaced bands and servos,bores good.After overhaul test drove and trans shifted perfect....no 3rd slip .....except after a few miles p0741 came on. Dropped valve body and found trans go tcc valve binding in bore.Repaired bore and valve and reinstalled vb. Test drove and slips in third but tcc working normal and p0741 is gone now. Only thing we did was drop valve body and work on tcc. This is exactly like original problem but was fixed until we un stuck tcc????? Going to drop vb when cools off and recheck gaskets. Was just looking for some advice! Thanks
Replaced valve body with reman and now have 123 shift. neautral in 4th delayed reverse. Code for 4th gear ratio. Completely different problem now with this vb.
