The P0300 misfire code is causing the TCC to unlock. Nothing wrong with the transmission. I would set the TCC max duty cycle table to 100 & the min to 90, that way the TCC is either on or off.

If so, I wonder if it just needs some fresh front brakes, or if there is a proportioning issue, where the rears are getting too much pressure...?

Tough to say on the P0300, should be something you canmake sense of with some more logging...

Happy tuning

Thanks man, it's literally PUSHING the tires, they're locked up, the tires are literally sliding. I'll see if I can get a video somehow. I've got Napa ceramics all the way around, 2 piston calipers up front, disc rear. Probably need to invest in a line lock, but it's going a little far for a stupid problem.

Just noticed they happened in together.

Lovely LS1Edit doesn't provide tcc duty table. I can set mph/tps of apply/release and that's it. I was pissed when I found that out as we removed the restrictor from the input shaft to give full fluid flow to tcc upon apply so it would feel like 5th gear / hold. Now all I get is a nice ramp down to lock up.

So to break down, trans needs bandaid kit for tcc / P1870, and I have to figure out why I'm getting P0300 codes. Will see if I can get a hookup @ stealership to do a crank relearn.
