i bought a 07 tbss with a 4l80e trans already swapped in it. noticed tcc never locked up. data logged and found it to command on. fast forward to the other day. trans took a shit. i heard trans pump noise. lost all forward gears.
it had a 3600 stall with no trans cooler. and not locking up. i mean it was a matter of time.
i just want to make sure the trans tune looks ok. and what i should change now that a built 4l80e is going in. thanks.
i have one tune attached using bluecat, i have not tried it yet.
