Ok my truck is still acting up with the transmission, i have checked my solenoids and they are both working, i replaced the filter and oil, i have no idea now to what is causing my transmission to go into limp mode, What fuses go to the transmission that could be causing this?
IGN0 is fine and isn't popped.

The solenoids work but with a multimeter i'm not getting 12 V into the left one( on the picture)
here are the pics.




Any ideas?

What year is the truck? And what code is setting?

When you say IGN 0 fuse is good, are you visually checking it? Or does it actually have 12 volts? Reason I say that, is ignition switches goes out quite ofter. And will only supply say 5 volts to the IGN 0 fuse.

Visually ill check that in a bit
and im getting these codes
p0758 Solenoid Circuit B
p0785 shift timing solenoid malfunction
p1810 TFP Val Position SW Circuit Malfunction
P0748 - Pressure Control Solenoid Electrical

My truck is a 2000 RCSB Silverado, came with a 4.3 i swapped it out for a 2002 5.3. It came with everything harness and computer. so when it was in it fired right up. it worked once for like about 10 min then went into limp mode again -_-
If i'm reading 5V then its the ignition switch?

I don't have the wiring diagrams in front of me... but if your transmission was happy before the swap and after the swap you have multiple electrical codes, then I would suggest that there is an issue with harness compatibility. Maybe someone can set me straight on that....

Also, be sure to check all of the system grounds. If you did not get one hooked up properly then you could have a multitude of issues.

Hmm maybe i could've missed a ground, but i need a diagram, ill try and see if i can find them online. I have a feeling its a ground thats missing
