6R60 Shift Kit 2006-2014, new and ready to install. Fits the 6R60. Ships fast from the USA.
If you own a 2006-2008 Ford Explorer or Mercury Mountaineer with the 4.6L V8, the six-speed under it is a 6R60, and the complaints that bring owners to this part are predictable: a shake at light throttle between roughly 28 and 46 mph, upshifts that stretch out once the fluid is hot, and a thump as the SUV rolls to a stop. The kit in this listing is TransGo's SK 6R80-A, the GEN1 valve body repair kit. The 6R80 name on the box is just TransGo's family label; their own fitment line reads 6R60, 6R75 and 6R80 GEN1, 2006-14, which is where this title's year range comes from. It is new and goes in through the pan.
The 6R60 is Ford's licensed build of the ZF 6HP26 design, made at Livonia. All of its shifts are clutch-to-clutch, so shift quality depends on line pressure being steady at the moment one clutch releases and the next one applies. That pressure is set by a single pressure regulator (PR) valve. After a lot of heat cycles the valve and the aluminum bore it rides in wear, line pressure starts to wander, and the computer compensates by lengthening shifts until it runs out of room. TransGo's kit swaps the factory PR valve for a patented two-piece hardened steel valve with a new orange spring and an end cap without ID grooves, sized for the .495 in GEN1 bore. It also replaces the torque converter clutch (TCC) regulator valve with a steel valve and a small white spring, which is the part aimed at the converter quiver. Extra wire retainers are included because the originals often break when they come out.
Get the fluid right first. Ford's 2007 Explorer owner guide lists the six-speed on MERCON SP and the five-speed on MERCON V, so a wrong top-off is a real possibility on these trucks. TransGo also notes that shops installing this kit with a fresh fill of MERCON SP report the quiver usually goes away. Next, scan for codes. A solenoid circuit fault or speed sensor fault is an electrical repair and has to be fixed first; our shift solenoid symptoms guide explains how to test the solenoids this family shares. If the codes are only ratio or performance codes and the shudder appears when the converter clutch applies, the regulator circuits are the likely cause. Our 6R80 family common problems guide lays out the rest of the checklist.
Factory 6R60 applications are the 2006-2008 Explorer and Mountaineer with the 4.6L V8. For 2009-2010 the V8 Explorer and Mountaineer moved to the 6R80, which this same GEN1 kit also covers. Explorers of these years were also sold with a five-speed automatic, so check the transmission code on the door label before you order. Every 6R60 left the factory with a GEN1 valve body, but if yours has been replaced, measure the original PR valve land: .495 in takes this kit, .514 in is GEN2 and needs the 2015-2019 GEN2 version. When in doubt, send us your year and VIN, or browse the 6R60 and 6R80 parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 6R60 was used in the 2006-2008 Ford Explorer and Mercury Mountaineer with the 4.6L V8. The 2009-2010 V8 versions use the 6R80, which takes this same GEN1 kit. V6 Explorers of these years used a five-speed and this kit does not fit them.
TransGo sells one GEN1 kit, SK 6R80-A, for the whole 6R60, 6R75 and 6R80 family from 2006 to 2014. The 6R60 uses the same GEN1 pressure regulator valve size, .495 in, so the kit is correct for it.
That quiver is the main complaint the kit targets, through the new TCC regulator valve and the new PR valve. TransGo notes that if the problem has gone on for more than a month or two, the converter may also need replacing, although shops report fresh MERCON SP plus the kit usually cures it.
Ford's 2007 Explorer owner guide lists MERCON SP for the six-speed. Check the level hot at 190 F on a scan tool, at the top of the hash marks.
Yes. The valve body comes out through the pan, so the kit can be installed with the transmission in the vehicle. It is also commonly installed during a full rebuild.
On a high-mileage valve body TransGo recommends a fresh set of solenoids. A 2006-2008 6R60 uses the earlier 2006-2010 style solenoids, so match the part to your year.
