installed chip, tranny overheated in driveway??

[SINSTER96]

I installed a TW chip. The truck was idling on the smoke setting for 15 mins in the driveway, I checked the tranny temp and it read 304 degrees and I had no line pressure and tranny was slipping bad. I didn't even drive it.. well I was going to. I never heard of a tranny getting that hot doing nothing, unless the smoke setting would do that? I wonder if it computer related, like a false reading. Hope the tranny is not shot.

ok I took the chip out and everything seems find. tranny works, tranny temp sensor is reading normal. It might be the chip, I may not have cleaned the connected on the PCM properly. All 6 pos on the TW chip works, except for the tranny(slips, no line pressure), so I wonder if I messed something up because my problem is computer related.
any ideas?

I also have a TW chip but I've never let it idle on smoke other than that I've never had a problem.

Never heard of this happening, I will check the burns on the chip and see if anything in them could possibly cause this, how did you clean the pcm?
