So I overhauled the throttle bodies today and wow big diference in throttle response!
Still getting the TRANS PROGRAM error though
Next up is a filter and trans fluid change, i know I should have done this off the bat. Thinking of replacing the speed sensor while I am in there but I have has no issue with the speedo.
also clean the plug which is between TCU and the transmission, on the side of the transmission. Often this plug is filled with trans fluid, as the plastic is brittle around the pins in the trans plug and that causes contact problems. Can be cleaned with brake cleaner.
When the trans pan is off and you change the filter: I would then also open up the valve body and clean it, remove every solenoid, clean the passages, test the solenoids and reinstall them. Also check for broken pressure springs in valve body.
Lot of info here
