About this product

If your 2011 or later Ford Super Duty with the 6R140 flares on the 3-4 upshift, slips in fourth, fifth or sixth under a trailer, or a rebuild turned up a torn or hardened overdrive clutch seal, this is the part you are looking for. The listing is titled as a 2011 clutch drum, but what ships is a new Precision International overdrive clutch piston set, manufacturer number K36900V-99: the bonded overdrive clutch piston (Ford BC3Z-7A262-G) and the molded piston retainer, also called the balance piston (Ford BC3Z-7H360-A). The drum itself is not included. Interchange numbers on the set are 236960AK and A236960AK.

What the overdrive clutch piston does in a 6R140

The 6R140 is a clutch-to-clutch six-speed with five clutch packs. The overdrive clutch, often called the 4-5-6 clutch or E clutch, is one of the three driving clutches, and it is applied in fourth, fifth and sixth gear. ATRA's apply chart shows it is fed by shift solenoid E, a normally high solenoid, which is why the overdrive clutch is on whenever SSE is commanded off. When oil reaches the apply side, this piston pushes the pack together so the drum drives the gearset.

Because the overdrive drum spins at input speed, oil trapped behind the piston wants to apply it by centrifugal force alone. The balance piston in this set closes off a chamber on the other side that fills with oil and cancels that force, so the clutch releases cleanly on a downshift. The rubber on both parts is bonded to the steel, so there are no loose lip seals to roll or cut during assembly.

Symptoms of a leaking overdrive clutch piston

Slipping only in the gears that share the overdrive clutch points to this circuit. If every gear slips, look at line pressure and the pump first.

How to confirm it before buying

Check the fluid hot and pull codes. A weak line pressure command or a sticking SSE gives the same complaint, so work through the 6R140 3-4 clutch failure guide and the shift solenoid guide before you tear the unit down. On the bench, air-check the overdrive clutch: a hiss from the piston, a lifted bond line or a cracked balance piston confirms it. A leak at the sealing rings instead means the drum journal or rings are the problem.

Fitment

The set is listed for all 2011-and-later 6R140 units, gas and diesel, in the F-250, F-350, F-450 and F-550 Super Duty. The 2011 in the title is the first year, not the only year. The genuine Ford version of the same two part numbers is also in stock as the 6R140 OEM overdrive piston set if you prefer factory packaging. Compare your old piston, or send us your year and VIN, and browse every 6R140 part on the 6R140 parts page.

6R140 Clutch Drum 2011: common questions

Does this include the clutch drum?

No. It is the overdrive clutch piston and the balance piston only. Reuse your drum if the bore and sealing ring journals are in good shape.

Is it only for 2011 trucks?

No. The set is listed for all 2011-and-later 6R140 transmissions, gas and diesel. Send us your VIN if you want the fitment checked.

What is the difference between this and the OEM set?

This is a Precision International aftermarket set, K36900V-99. The OEM listing is the genuine Ford BC3Z-7A262-G and BC3Z-7H360-A in Ford packaging. Both replace the same two parts.

What clearance should the overdrive clutch have?

ATSG's revised specification is 0.060 to 0.080 inch for the 4-5-6 clutch on both gas and diesel units. Adjust with the selective snap ring.

Do I need a relearn after replacing it?

Yes. Reset the adaptive tables with a scan tool after refilling with MERCON LV, then drive through several full upshift and downshift cycles.
