There is no dipstick on your auto trans. Checking it is a real PITA The trans pan has 2 plugs in it. The one on the very bottom is the drain. The one in the corner, up higher in a recess is the check/fill plug. To check, the engine must be warm and running, tranny in P. Remove the plug and fluid should dribble out. If it doesn't it's low, fill until it dribbles out, while engine is running. Obviously the truck must be on a lift or up on jackstands.

I had that problem too and the issue was a loose wire connecting the engine control modude to the crankshaft sensor switch. The engine control module does not sense where the crankshaft position is when the wire moves, and that causes things to go snaky, such as the transmission and cruise lights coming on. This issue took a good mechanic in Syracuse one and a half weeks to find. Total cost was $425.00,$395.00 for labour, and $.99 for the new wire. Good luck!

SOURCE: What does the diagnostic code
Hi, your vent valve has malfuntioned. The vent valve is near the tank, and has a hose to the tank and a solenoid to close it. Check the wiring/connector. If OK, try applying 12 volts directly to the solenoid. If it does not click when voltage is applied, replace the solenoid/valve. Evaporative Emission Control System Vent Control Circuit Malfunction
