log 1-30 freeway.hplTransShift3.hpt Here is my log and current tune.
Hi guys,
In my ls swapped blazer I have a 6.2 Ls3/4l80e combo. It is ran with the e38 and t42. It has a Circle D Specialties 3200 stall/TSP cam. My current issue is when I am driving down the road with the gear selector in overdrive, it will throw a P0894 code for internal component slippage and go into full line pressure when the following conditions are met: trans is in 4th gear, and tcc is locked. However, when you have the gear selector pulled down into 3rd, the transmission shifts fine, and will go into lockup while in 3rd gear and no code is set.
Firstly, I tried to resolve the problem myself by changing the tcc lock up to a later time, thinking this would keep it from slipping. This did not solve the issue.
Now, I got to looking at the tcc slippage. As you can see in the log, while in 4th/lock up, the slippage is ~130. Is that too much? Is there something that can be changed in the tune to resolve the amount of slippage? Or, is my brand new converter shot? In the attached log, I was manually locking up the converter to keep it from jumping out of gear and setting the code like described above.
I am new at the whole tuning side of things and just trying to see if I could fix this myself.
Any help is appreciated,
Clint
