4L60E Pre-Mature Lockup Question
Hi All,
I have a 4L60E behind a 454. Took pretty good care to build the tranny strong enough.
I am having a situation where the Torque Converter seems to be locking up prematurely... it is happening about WHEN it should happen but according to the scanner- the ECM has not yet commanded a lockup. So what it feels like is a lot of mid throttle hesitation where the RPM's go up and down kind of erratically as the TQ locks up and unlocks.
I know it is the TQ b.c if I slightly touch the brakes to force the TCC off... then the issue goes away.
I am having trouble understanding if this is a chip thing or something else maybe asking the TCC to engage or is it doing it itself???
This didnt happen for a year or so but just recently started happening.
Any thoughts welcome!!!
