tcc problems

[Taz]

Ok thanks for looking i may be hearing something else i just noticed the rpm jump when i back off the throttle thought it was unlocking the converter

Yes sir, it is unlocking the TC when you release the throttle - that is what truck tunes do. If you review your logs, when you ease up on the throttle, you will see the TCC status go from "Locked" to "Coast" (which means that it is getting ready to unlock), then to "Off".

Does the torque converter slippage look normal for being locked

BTW: TSTATE09 and TSTATE10 are particularly useful because they show the reason the TCC is unlocked.

[danny68ss]

Is that amount of slippage normal while locked

[joecar]

That's ok and is normal.

Ok i added the other pids and what im hearing is when it go to full lock it only does it at around 30% throttle anyway of adjusting that
