Need help:

5.3 small cam
freshly rebuilt 4l80e with circle D 3000 stall
82 s10


Shifts seem slow. I'm not sure that it's actually shifting to 4th, i manually pull back to 3rd and the rpms stay the same.
I'm also trying to understand the relationship between input output shaft speed and RPM, i also noticing TCC slip at times. Also tcc mode: apply en, apply. I was only expecting to see lock and off.

I've air checked 4th gear, looked over the valve body, everything moves, nothing is binding.


IS the trans slipping, converter slipping

Here is a video of the log:

Figured out how to include, tune, log and config. Hope someone can shed some light on what is going on.

have you tried to shift it into 4th using the vcm scanner under special functions?

Replaced both shift solenoids and what do you know, it shifts beautifully
