2007–2014: 6F50 six-speed automatic (FWD/AWD). 2015–2024: 6F55 six-speed automatic. 2021–2023: 8F35 eight-speed automatic (2.0L EcoBoost ST models). All AWD models include PTO unit (power take-off) for rear axle drive.
Diagnosis begins with a full OBD-II scan and road test to isolate the fault. Valve body solenoid failures on 6F50/6F55 can often be repaired without a full rebuild ($550–950). TCC shudder is addressed first with a Mercon LV fluid exchange; if shudder persists, the torque converter needs replacement. PTU service (fluid change or seal replacement) is handled separately from the transmission.
Mercon LV ATF for all 6F50/6F55 units. 8F35 uses Mercon ULV. PTU uses Ford Friction Modifier fluid. Never substitute generic ATF — Ford transmissions are calibrated to specific friction properties.
Solenoid/valve body repair: 1–2 business days. Full 6F55 rebuild: 3–4 days. Torque converter replacement: 1 day. PTU seal: half day.
"Honest diagnosis, fair price, and the repair was done right. Chicago Transmission has been my go-to for years. Wouldn't trust anyone else with my car."
"The free diagnostic alone was worth the trip. They found the problem fast, gave me a written estimate, and completed the work on time. Exceptional service."
"Family owned and it shows. They treated my car like it was their own. The lifetime warranty on my rebuild gives me total peace of mind. Highly recommend."
On an Edge with EcoBoost, highway shudder between 35–55 mph under light throttle is almost always the torque converter clutch (TCC). Start with a Mercon LV fluid exchange ($149). If it continues after 500 miles, torque converter replacement is needed ($550–850 installed).
Likely the PTU (power take-off unit) — the small gearbox that transfers power to the rear axle. A leaking PTU seal can cause vibration before full failure. PTU seal and fluid service runs $250–450 and should be caught early.
3–4 business days. We stock 6F55 rebuild kits for prompt turnaround — no waiting a week for parts.
On the 6F50/6F55, harsh 1-2 shifts usually mean valve body solenoid wear. We can often repair this without a full rebuild ($550–950). Get a free diagnostic first — we'll pull the solenoid codes.
The Edge uses the larger 6F55 (AWD/heavier-duty) vs. the 6F35 in Escape. Different units, different rebuild kits, though both use Mercon LV fluid. We service both.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
