So I have a 2007 Tbss and was having tranny it would slip and I would need to let go off the gas pedal for it to shift so I got a rebuild on it and same thing is still happening don’t know what the problem is and yes the input speed sensor was replace

Which shift is not happening? All 1-2,2-3, and/or 3-4

each one has different troubleshooting steps.

As for the rebuild do you have a copy of all that was replaced? More importantly did they pressure check the valvebody? That causes a lot of issues with the 4L60/65/70 over the decades

I would have pulled the valve body and pressure tested the whole thing for any bore wear or cross leaks. None of the electronics were replaced which is surprising as it’s less than $100 in parts for a new harness and solenoids, one of those while you’re in there replacing all the things…
