4l60e to 4l80e segment swap no shifting
I just did a 1994 4l80e swap on a 06 silverado 5.3 that was originally a 4wd and have brand new solenoids, torque converter, Custom drive shaft, new 4.10 gears,new neutral saftey switch, new wiring harness with the 4l80e adapter harness that connects to the transmission.
I am not getting any shift into gear at all I got my truck tuned for it and added the rear speed sensor, Pin A to 22 and PIN B to 23. on the original harness to connect to the transmission I disconnected the Tan w/ Black Stipe and white wire because i seen videos that these aren’t supposed to be used? And Put the BROWN wire into the S pin. Currently I am still getting a P2761 Code and have No transmission fluid in the tranny. Should i added 13.5 quarts in first and try it or am I gonna have to take the pan off again? Please i need help anything will help. am i missing anything?

Well damn I have ran the truck a few times trying to get it into a gear. But that may explain my problem. Will adding transmission fluid resolve the P2761 code that i am getting? or will it be a working issue?
#6
The code is an electrical code and wiring related . As for the adding fluid I am gonna be surprised if you didn't kill the pump

Auto transmissions are just like engines, they need oil to operate. Would you expect a freshly rebuilt engine to start up and run with on oil in it and not damage the engine. At the very least the Transmision pump bushing, or in engine terms the pump bearing is damaged. Possibly the pump gears, engine terms the oil pump.

I can't say for sure. I'm not there to hear it or know how long it was run without fluid. Most likely the damage from being ran without fluid is the cause.
Like Frank said the code is an electrical problem.

"Clicky, grindy, clunky sounds" are never good in any transmission - electrical problems or TCC solenoid problems or not. I'd say you are destroying internal hard parts and only making matters worse and more expensive to remedy. A rebuild or replacement is in your very near future. And don't forget - add fluid.

Here is how I would handle this if i ever did such a thing, Logically, 1st since it does not require the engine to be running or the trans to work, I would tackle solving the electrical issue so it would be out of the way. get rid of it and the code gone. That way when you go back in your ready to go.
Then if its making all the noise you say I would remove the trans and disassemble and figure out all that was damaged checking at least back through the fwd clutch assembly as in park all of this can turn from drag even with no oil . Also I would assume possible converter damage and handle it as such .
I know, not what you want to hear but just the facts.

I am certain it is a wiring or connector issue .
#16
Would it make sense if i put the plug backwards on the “Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open” ? That’s what code that keeps popping any idea what wire pin that would be on the connector?
How could i fix the wire issue? maybe a shortage? possible a relay?
