I used the advance auto parts store scanner to read the codes I’ll try and find a tech2

what i mean is the diag tests that can be ran with one, not trying to pull more codes. you can make the abs module do self test and other things to verify exactly where the issue lies without pulling anything apart.

Gotcha i haven’t worked with them much so don’t know what all they are capable of.

Pretty sure i found the culprit of all this. I kept hearing the hiding/ticking /arcing noise and it was coming from under the back seat i could swear it. So decided to just look at the fluid in the Tcase and some other stuff.

Pulled plug on tcase and maybe a shot came out along with a bunch of sludge woe is me. So i got as much sludge out as i could abs filled her up with some 5w30. As I’m filling it up i see my driveshaft yoke looks odd. You guessed it the tail shaft bushing has pushed out and is just loose sitting on driveshaft yoke.

So with all that’s happening limp mode, valve stuck, weird shifts, lost coms with Tcm all of this intermittently but constant at the same time. Maybe even the abs issue?? Idk.

I believe the bushing came out and got everything out of line and now the tone wheel and output speed sensor are wonky.

Probably just going to get a new Tcase i don’t have the luxury or time to tear it apart and then figure out what all is wrong. But thought I’d let everyone know.
