Remanufactured solenoid bank for the Ford 6F50 and 6F55 six-speed, OE AA5P-7Z369-AA, for harsh shifts, slipping and delayed engagement.
A 2007-2018 Ford Edge, Explorer, Flex or Taurus, or a Lincoln MKS, MKT, MKX or MKZ, that bangs into second gear, flares between shifts, hesitates for a few seconds before it moves off a cold start, or has thrown a P0750-series solenoid code is pointing at the solenoid bank bolted to the 6F50 or 6F55 valve body, not the whole transaxle. This module is the solenoid assembly only, OE number AA5P-7Z369-AA (superseding DA8P-7G391-AA and DA8P-7G391-AB) - your existing transmission control module stays in the vehicle.
The 6F50 and the wider-ratio 6F55 are clutch-to-clutch automatics with no separate mechanical shift valve train, so every gear change depends on the TCM firing the correct solenoid at the correct pressure. This module carries the pressure control and shift solenoids that sit between the TCM's wiring and the valve body's hydraulic circuits. When a bore wears or a solenoid's internal spring and armature drift out of spec, the module stops delivering clean, repeatable pressure to one or more clutches, and the transmission starts hunting for the shift point instead of hitting it. Our 6F35/6F50 problems guide covers how this family's hydraulic and electrical faults show up together.
Pull codes first. A solenoid performance code (as opposed to a solenoid circuit/electrical code) usually means the solenoid itself is sticking or has drifted out of calibration rather than a wiring fault, which is the pattern this module corrects. If the scan tool instead shows an open or shorted circuit on a single channel, check the internal harness connector at the module before replacing the whole bank. Our 6F50 TCC solenoid listing is useful background if the complaint is isolated to converter lockup apply and release.
This module fits the 6F50 and 6F55 as built into the 2007-2018 Ford Edge, Explorer, Flex and Taurus and the Lincoln MKS, MKT, MKX and MKZ, under OE number AA5P-7Z369-AA. Ford revised this solenoid bank's casting and connector more than once across an eleven-year production run, so confirm your old module's part number or connector style before ordering, or send us your year, make and model and we will match it.

Drop the pan and filter first so metal and clutch debris from the failing module does not recirculate through the new one. Unplug the internal wiring harness at the module, remove the retaining bolts, and lift the module off the valve body squarely so you do not bend the harness pins or distort the gasket surface. This unit ships complete and function tested - nothing is reused from the old module. Torque the bolts evenly from the center outward, reconnect the harness, and refill with Mercon LV only. Pair the swap with a fresh 6F50 overhaul kit if the fluid has never been serviced, since contaminated fluid is what wears these bores out in the first place. After the install, clear the codes and run the transmission adaptive relearn so the TCM re-learns its shift pressure tables against the new solenoids - skipping the relearn is the most common reason a good module still feels harsh for the first fifty miles.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This is the solenoid bank only, OE AA5P-7Z369-AA. Your vehicle's TCM is a separate component and stays in place - only the solenoids that bolt to the valve body are replaced.
Change the fluid and filter at the same time with Mercon LV, and inspect the valve body itself for scoring if the old module failed from debris. If the fluid has never been serviced, pair this with a full overhaul kit rather than installing a clean module into dirty fluid.
A P0750-series solenoid performance code, a hard or flared shift that is consistent on one gear change, or a long engagement delay on a cold start all point to the solenoid module. A TCM fault usually throws a different code class and often affects every gear at once, not just one shift point.
Yes. Clear the stored codes and run the transmission's adaptive shift relearn. Skipping this step is why a correctly installed, good module can still feel harsh or flare for the first few dozen miles - the TCM is still working off its old, worn-solenoid pressure tables.
It covers the vehicles and years listed under OE number AA5P-7Z369-AA, but Ford updated this bank's casting and connector during the production run. Match your old module's part number or connector style, or give us your year, make and model before ordering.
