pcs 4l80e trans controller / guys help Hi all i have been having issues when the trans gets quite warm. It does not want to upshift or down shift, it seems to hold ither 3rd or 4th gear. when the trans cools down it is fine . it seems to be temp related , are there settings that need to be altered to address this problem

There is a setting in the TCC lockup parameters to keep the converter locked above a certain temp. Mine is set at 230. There is also a temperature vs line pressure table in which all values are set to 0 above 118 on mine.
