HELP P0766 and P2703 Code

[drhoades3862]

Truck messes up in fourth gear it either stays in 4th and wont shift or will shift to 4th and not to 5th. If it makes it to 5th it will down shift to 4th and back to 5th. Its obviously a solenoid issue but which one is it i need to replace??

I had the same code and the tranny was burned, selenoid malfunction is more often cause by clutch debris that clogged them.

i have the exact same problems and it finally threw codes today, same codes as yours. was the trans fried in yours or did the solenoid fix the issues? How much do the solenoids run? Also, does anyone have any input as to whether i should do all solenoid while im in there or just the D and call it good for now?

Just had the same codes come up today as I took off a little aggressive up to about 45mph. P0766 and P2703. I was running the Spartan 310 tune and cleared the codes and turned the truck off and restarted. Everything seemed fine and no other problems yet. Should I start saving for a built transmission or maybe select a smaller tune and try and hold off being aggressive with it.

Yup I would. It prolly won't be long.

Yep, take her easy and save some $$$$, sometime it's the converter that create the debris that clogged the selenoids, weak part in those tranny.
