I have a couple issues; 1. While in 4 (hi or low) and moving forward, everything seems fine until i make turns and you hear grinding sounds. 2. While in 4 hi or low and trying to back up, the truck will move for a few feet then the wheels lock up.

We've cleared the code after replacing cap. Came back on within a day or two. Truck runs normal but need to get cleared for inspection.
No noise when key turns
The truck was running fine all that day. Stop and filled the tank and made two or stops and the engine cranks over but truck never started up.
Which solenoid should I change if not going into 3 third gear. Or alway burn 3 and 4 clutch .

No cold air when idling
I hear water sloshing from the mid to rear area of the truck. Not wet inside. Sounds like it's trapped in the chassis. I saw posts recommending drilling drain holes. These holes, I read, were added to later year models. I'd like to know exactly where to add them. Thank you.
