09 Explorer Throwing a P0658 Code

[NeXTLoop]

Hi All,

I've searched for info on this but am not turning up much definitive information. I just bought a used 2009 Explorer, V8 4x4 w/ 138,000 miles. The truck has been well-cared for and is in immaculate condition.

My brother-in-law (a mechanic by trade, almost a mechanical savant really) did a drain and fill right after I bought it. The fluid had obviously been changed before, as it was definitely not 138,000 mile-old fluid. There were also no abnormal metal shavings or kludge.

Twice now, however, it's went into Limp Home Mode with a P0658 code, which is an Actuator Supply Low Voltage error. Turning the truck off and back on seems to clear it and it runs fine. I've read that the solenoids can be prone to crud building up in the fluid.

Has anyone else experienced this? Any fix that's worked?

Thanks,
Matt

There are no FWD Explorers in 2009, just RWD, AWD or 4x4

I assume he did transmission drain and fill.

From what I read, this error is caused often by contamination of the fluid.

What did he use to refill ?

Mercon LV is the proper fluid for your year.

Yep, you're absolutely right about FWD. Typo. It's a 4x4. The contamination seems to be what I'm coming up with too. The fluid was Mercon LV, per the spec. This vehicle had an incredibly light-use life. After we changed the fluid, I did do some towing (nothing close to the limit, only about 4,000lbs). I'm wondering if the new fluid, with all its fresh additives, combined with the heaviest use the vehicle has ever seen jarred crus loose that's now collecting around the solenoids.
