Re: E4OD Problems
The E4OD is a great tranny and is very strong...which is why Ford used it in all V8 applications including the Powerstroke diesel. If it can take the torque of the diesel, it can't be all bad. As long as you maintain it properly, it'll last a long time.
Regarding your problem, I'd start with checking your fluid level. If the fluid level is ok, it may be time to drop the pan and change your filter and put in fresh tranny fluid. While you're at it, drain the torque converter by removing the rubber dust cover in the bellhousing to get to the drain plug in the TC. You may have to bump the engine over to rotate the TC to get to the drain plug.
If that doesn't solve your problem, the dealer is your best bet as the shifts, line pressure, torque converter lockup, etc. are all computer controlled so diagnostics can be difficult without the proper equipment.
