tcc dancing i believe...like i said when i manually lock it in it stops. Any ideas? theyre is a spot for a trans relay in pdc box but no relay is mounted there instead the lead for the override switch has got a male spade terminal diving into one of the terminal points. its been this way since i got it but everything transmission wise was working fine. i reseated this termination and i think the tps/iac swap has helped some but its still oscillating from time to time....not as much thought

 

Have you replace the TCC solenoid yet? They are not an uncommon failure point......

 

replaced torque converter clutch and replaced battery terminals fixed the issue of dancing tcc for a few thousand miles now its back again. Could this be pcm related solely?

 

Might be wiring between PCM and trans too....... Would be nice if you could do some data logging, and see what is going on when the condition presents itself.
