Expands and resizes the rigid Teflon sealing rings on Ford 6R140 input, turbine and stator support shafts so they seat without cracking.
This seven-piece kit is for the shop that wants one set covering every shaft-mounted Teflon ring in a Ford 6R140 TorqShift: input shaft, turbine shaft, stator support and front stator support. It replaces the two OEM special service tools T-307653SAC and T-307657SAC, and it fits more than the pickups. Applications include 2011-up F-250 through F-550 Super Duty, 2012-up E-350 and E-450 vans and cutaways, and 2016-up F-650 and F-750 medium-duty trucks.
The 6R140 seals its rotating oil feeds with rigid scarf-cut Teflon rings. The rings at the stator support carry fluid from the pump body into the input and turbine shafts, feeding clutch circuits and the converter. A new ring is coiled larger than its groove, and once it is on the shaft it sits proud of the shaft diameter. The guided expanders spread a ring just enough to pass over the shaft and drop into its groove. Then the matching downsizing sleeve is pushed over the shaft to squeeze the ring back to bore size and hold it there while the Teflon takes a set. Slots in the sleeves let you see that the ring is actually seated in the groove while it is compressed.
In the box: four downsizing sleeves, two guided seal expanders and one drive handle. The sleeves are a hard wear-resistant polymer with a smooth bore, so they do not mark the shaft or the ring.
Before you pull the transmission for rings, prove the pump and controls are sound. Our 6R140 pump failure guide covers pressure testing and the filter intake seal that causes cold no-engagement, and the delayed engagement guide lays out the order of checks. ATRA also points to the pump stator sleeve, which can partially turn and block converter charge oil, as a cause of overheating, so inspect the sleeve whenever the stator support is out. With the unit on the bench, an air-check that hisses at the shaft journal rather than at the piston points to a ring.
Fits the Ford 6R140 in 2011-up Super Duty F-250, F-350, F-450 and F-550, 2012-up E-350 and E-450, and 2016-up F-650 and F-750. Other Ford six-speed and ten-speed units use different shaft sizes, so match the transmission code on your case tag before ordering. Send us your year and VIN if you need us to check. Shipping weight is about 11 ounces. The full range of 6R140 parts is on our 6R140 transmission page.
Refill with Mercon LV, then clear the adaptive tables with a scan tool and complete a relearn drive.

It replaces Ford special service tools T-307653SAC and T-307657SAC, covering the input shaft, turbine shaft, stator support and front stator support rings.
Yes. It is listed for 2012-up E-350 and E-450 and 2016-up F-650 and F-750 with the 6R140, as well as 2011-up F-250 through F-550.
Seven pieces: four downsizing sleeves, two guided seal expanders and one drive handle.
The downsizing sleeves have slots so you can see the ring in its groove while it is compressed. After removing the sleeve, the ring should spin freely with its scarf joint closed.
Use clean Mercon LV, the fluid the 6R140 is filled with.
