Been having an issue with tcc staying locked...thought it was tune so I checked and made sure all the misfire tables were raised. logged for a few and added the tcc channel and saw it lock then unlock. Checked for codes and sure enough tcc stuck closed. Manually lock the tcc and it holds fine. Any ideas? Trans was rebuilt 2500 miles ago and I just put in a new billet pump and new stall converter days ago. I noticed more tables available from when it was tuned last in 2017. Also turned off the misfire mil.
update: after logging I saw 80% tcc slip, 1800 rpm tcc slip at 100%duty cycle but line pressure is showing only 90 max..sounds off. Shifts fine fast and firm feels like its locking properly as it resembkes another gear but judging by the slip I'd say its bad... possibly internal issue. Just replaced converter and billet pump in a built lvl6 rpm trans.
