Hey guys I am just getting started on this tuning stuff, I was reading on the HPT web site and found this: (TCC Lock During Shift: This switch determines if the TCC will remain locked during a shift. Note: This is extremely hard on the transmission and the TCC (if you enable this expect things to break).
in the help section. I looked at the stock tune and it was enabled. I was just wondering is this normal, where should I put it enable/disable. I just spent way too much money on this truck to kill the transmission right now. I know its coming I just need it to last a little while.

 

Set it to disable. I don't think I have felt a shift while the converter was locked, not sure what would happen.

 

It is normal for it to be enabled in the stock tune. I don't know what is best, but I have left mine enabled up to this point and have not experienced any problems. Of course when and where it actually stays locked during a shift is still dependent on the TCC lock/unlock settings vs. the shift settings.

 

any more opinions

 

Mine is set to disabled

 

The stock setting for min TC lock PWM is way soft.
In the stock calibration there is a LOT of slip allowed due to the low min PWM values.
This gives sort of a semi engaged TC clutch, way different to the performance oriented 90 PWM setting recommended.

Having the "lock during shift" flag set to ON with a performance tune (for example min 90 PWM) is most likely a bad idea.
I have done it by mistake, reflashed the correction after first lock up!!!
It felt like "call the trans guy for a replacement" kind o shift.

Disable it...
