Re: 4L60E Problem-Rocket Scientist Needed
Hummm (thinking), that could be. They are using a Howell wiring harness to adapt the 1998 5.7L OBD-II engine / 4L60E tranny to the 1986 CJ-7 harness. They claim to have traced every wire that connects to the tranny to verify the correct routing. I'm not sure how much they have messed with the harness. Looking at the manual (I bought the whole 1 ft tall stack of factory manuals), lots of stuff will command "limp" mode, and several conditions will erroneously lock up the torque converter, but they all throw an error code when they do it. They're not seeing any error codes, which makes your idea sound plausible. Extra, erroneous signals commanding limp mode and causing the torque converter to lock, without a error condition being present, and no error code is thrown.
>>You may want to try shielding the harness.
What would work good for this, some of that foil backed heat resistant wrap? I shouldn't have to shield the individual wires in the tranny harness, right?
Thanks for the suggestion, Larry
