4L60E Problems - Need some input
4L60E Problems - Need some input Took the firebird out today for it's maiden voyage before I hand the car over to my kid for his graduation present (He doesn't know).
I'm having some issues with the tranny (4L60E)shifting properly, or should I say shift at all. I was expecting some issues as I accidentally lost track of a pair of wires (2xblack/yellow and 2xpink). I just need some input on which ones to switch around.
Here are the symptoms. It seems stuck in high gear, I'm guessing 3rd. Is it more likely that this is caused by having switched pin B and pin L around or by pin N and E being switched around? Or a combo of both? Please see attached diagram. I would really appreciate some help as I'm running out of time to have the car ready for my kid.

. Sorry no input here Ok so pin N and E were switched around. Got that fixed.
Had a chance to take the car for a quick spin. Now I'm getting 3 codes:
P2761 - Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open
P0740 - Torque Converter Clutch Circuit Malfunction
P0785 - Shift/Timing Solenoid Malfunction
Checked the voltages of Pin N and E. Pin N is 12V+ with ignition on (not running) and Pin E is only 3.6V with a small residual voltage with ignition off, what could be causing such a low voltage? I'm guessing this is what's tripping the codes. I need some ideas guys
