6l80 goes into 5th gear and stays there
I tuned a DI 5.3 swapped C10 awhile back with a 6l80 trans - everything went smooth no issues - now a few months later truck is back. Trans goes straight into 5th gear and stays there - I haven't ever seen issue like this before... really can't find anything tuning related and feel i just have a bad shift solenoid....
Hoping someone has seen this before....RICHARD PERKINS 71 C10 5.3 STG 1 LT A6 JP TUNE.hptRICHARD 71 C10 6L80 STAYS IN 5TH.hplRICHARD PERKINS 71 C10 5.3 STG 1 LT A6 JP TUNE.hptRICHARD 71 C10 6L80 STAYS IN 5TH.hpl
