4l80e problem on my first test drive I just went on my first test run after my 1.5 year build an have a problem.When the trans is in OD and I put the brakes on the motor dies when I come to a stop.I am thinking the converter(yank sc3000)isn't unlocking.I did check the switch at the pedal and yes there is 12 volts untill I apply the brakes.Can the tune /program in the computer be the problem or does it sound like a bad solinoid?Any advise please?Thanks

FYI the brake pedal should have no effect on the tq converter with an 80e. It will unlock at any time you are under ~5% throttle.

To let you guys know I did call wait4me about the tune he sold me and was told that John Speartechs 4l60e to a4l80e adaptor was wired wrong(plug and play)and that his tune was for sure right.So what I did is I pulled my computer out of my car and drove to Speed Inc sat down with Larry and he flashed my computer with a tune from his collection of tunes from pass customers.I then went home installed the computer and guess what?It's runs and shifts just like a stock car.All I can say is use Speartech and Speed Inc!Wait4me is a waist of time and money.I wouldn't let wait4me tune or mod the harness on my lawn mower.PM me for the long true story!
