In this video I’m going through a full inspection on a 2006 Ford E350 Econoline work van (this fleet calls it “the Hulk”) that came in with a big list of concerns. I start by verifying the customer complaints instead of guessing—rattle after shutdown, shifter indicator not lining up, and the big one: it slips only when it hits overdrive. I also point out a few other real-world items I found during the walk-around, like worn tires, a sway bar link/bushing issue causing a suspension rattle, and rear brakes/rotors that are due. For the shutdown rattle, I rule out the blower motor and track the noise with mechanic’s ears. The culprit ends up being the A/C compressor rattling as it spins down—basically telling you it’s about to come apart—so I recommend an A/C compressor and receiver/drier. The backup camera problem is simple: the power supply cord is missing. On the overdrive slip, I check fluid level/condition first (no overfill/aeration issue) and note there are no transmission codes to point us in a direction. Then I drop the pan on the 4R75E, inspect for metal (no chunks), and dig into the valve body. After checking check valves, servos, and the overdrive accumulator/servo seal and band, I find an intermittent sticking overdrive valve. At that point, I’m not taking chances—I recommend replacing the valve body as the fix path for this hydraulic overdrive issue.
