I tried tapping the brake pedal at hwy speeds and there was no change in RPM on my tach . I took it to a friends shop that has a trans shifting unit called a Trans X 2000 . We hooked it up at the plug on the trans and bypassed the ECM . Still no lockup I replaced the converter when I rebuilt the trans . I rebuilt the trans because I had no lockup, when I got the converter out I found some worn out pieces and went ahead and rebuilt the trans and replaced the converter.
Should I have voltage at the plug on trans, how much & on what pins .
Thanks
