4l60e Tranny not shifting?? Stays in 3rd?
I recently did a 5.3 vortec swap in my e30 BMW. The tranny came from a LS1 camaro. Got everything in a go out for another spin but seems like the tranny stays in 3rd gear?
Its doesnt shift at all. i do have the green connector hooked up and the VSS sensor. Im using the stock 5.3vortec PCM.
Whats making it not shift??

I wonder what could have made the PCM go bad? It came straight from a running truck.
Cause the pinouts on a vortec motor and the LS1s are the same, so that cant be the issue either? guess ill have to try my PCM in my buddies car or something?

Could the issue be because the tranny is from a 98 Z28? i havent checked the pinouts on both the Vortec wireing harness, and the LS1 harness, but i DO know that the LS1 and Vortec is the same pinouts, just some are extra, but was it different in 98??

well i finally got my obd2 port here, and i wired it in. Went to the nearest Auto parts store, and pulled the following codes....
P0118
P0740
P0753
P0758
P0785
P1860
I looked them all up and looks like of course most are all all tranny issues. So, now i gotta figure out what could be causeing it. GRR!
the P0118 is cause i dont have the sensor plugged in. I have an aftermarker gauge.

Well i looked into it a bit more today, and i tested the back side of my whole fuse block, and there were a couple that were not getting 12v power, so i found a source that wasnt being used, and wired it up. started the car, and i could deffintly tell it was getting power then , cause it had more torque feeling when i put it in "D"
BUT.... i start to drive, and as soon as it shifts it goes into LIMP mode again?
Something is going on?? I wonder if there is any fluid were the green plug would plug in on the tranny? maybe its shorting out that way?
