2016 Camaro SS, LT1/8L90E. DTC's P0700 in ECM & P16F3 in TCM, (Control Module Redundant Memory Performance)
Tried reprogramming the TCM first, But P16F3 returned, Ended up having to replace & program a new TCM. The TCM sure is in a bad spot.....On the right frame rail right behind the Auxiliary Radiator (red arrow).
GM's Techline Connect "TLC" was being extra finicky this morning, First I had trouble logging into ACDelco's Technical Delivery System "TDS" which was a Browser issue, Then TLC kept stalling when launched, Ended up deleting all the TLC software & starting over.
Of coarse the 8L90E is suffering with shudder issues because the ATF is spent or it never had the updated Dexron HP ATF installed. Unfortunately it's screwing with the relearn a little bit, Customer declined having me exchange the ATF. I'll have to put a couple more drive cycles on it in the morning.
8L90E's shift like crap in the first place.....Add in spent/incorrect ATF, A Relearn, And a kid that can't afford to maintain this kind of car makes for an interesting day!!
