Well I got the Mountaineer back and the new valve body (mectronic system) did not cure the problem. It still shifts like crap. I don't know where to turn now except get the lawyers going for a lemon law buy back. I can not believe that Ford produces this crap and can't fix it.
Dang, sorry to hear that….my hopes of fixing mine are dwindling. I had the PMC/TCM flash a few weeks ago and it continues to shift well except for very slow (approx 5 mph) stop and go (such as waiting in line at a stop sign) where it "surges" between 1st and 2nd and back to 1st with almost 0 throttle input. I'm going to drive it for another few weeks and see if any other shifts get worse.
I wonder if there are different revisions of the TCM/Mechatronic assembly and some folks have gotten a newer version with the issues resolved?
For those of you who's problems were resolved, It would be great if we could get clarification of what exactly was replaced by the dealer (the exact part number). There's been a lot terms thrown around....valve body, shift solenoid, mechatronic, TCM, etc. I pulled up the shop manual pdf on the tranny to better understand the design and what repair procedures are in place.
Mechatronic and valve body are synonymous terms in this 6R60 tranny. In the manual, any major shifting issues were repaired by replacing the mechatronic unit as a whole. The TCM is mounted above the mechatronic but is not replaced in the procedures (though is reflahed with latest calibration). The "shift solenoids" are part of the mechatronic. It is feasible to just repair/replace specific solenoids...but most dealers don't troubleshoot this deep and just follow the manual to replace the entire mechatronic unit.
Hope this helps. Please provide more info so we can all get this resolved.
Here is an extract from the manual:
----
Transmission Control Module (TCM) and Main Control Valve Body (Mechatronic)
The TCM and main control valve body are a combination of hydraulic and electronic control units. Both of these modules are installed in the transmission inside the transmission fluid pan. The TCM for the transmission is mounted on top of the main control valve body.
Solenoids
The hydraulic module contains one solenoid valve. The solenoid valve is activated by the TCM and is either open or closed. It is used to switch the position valve. There are 6 electronic pressure control valves which convert an electronic current into a proportional hydraulic pressure. They are energized by the TCM and actuate the valves belonging to the relevant switching elements.
