Any thoughts?
Any thoughts? I sent my tranny to get rebuilt because i lost all gears, I get it back and install it and I have no 3rd or 4th.
Things I have tried
-reverted to a factory 4L60e Tune, tune is posted in PCM section
-Pulled off the fat circular connector and I only had 2nd gear in Drive
-transcooler lines are warm when it runs
-when the connectors are on, it shifts from first to second GREAT, very strong
-I am not throwing any tranny codes
Anything else I can do to check to see if its mechanical or electrical? Or possible fixes?
