10R80 Shift Kit, new and ready to install. Fits the 10R80. Ships fast from the USA.
Owners of 2017 and later F-150s, Expeditions, Navigators, Mustangs and Rangers with the 10R80 ten-speed tend to find this page after months of the same complaints: a harsh or late shift that comes and goes, a flare between gears, a converter that shudders on the highway, or a fresh rebuild that never felt right. Many of those trace back to wear inside the valve body rather than to the clutches. This is a new TransGo shift kit for the 10R80, shown in the photo as a boxed TransGo kit with valves, springs and retainers in separate labeled bags. It carries a 1-year warranty and ships from the USA.
The 10R80 makes ten speeds from six clutches, and each one is applied by its own solenoid-controlled regulator circuit in the valve body. The main pressure regulator sets line pressure for everything, latch valves hold each clutch circuit once it is applied, and a separate TCC regulator and priority valve control the converter clutch. When those aluminum bores and steel valves wear, line pressure wanders and a clutch can apply slowly or bleed off, which shows up as a bind, a flare or a missed shift. TransGo's current kit for this unit, SK 10RL80-G1, replaces those weak points with drop-in parts. Its published contents are a drop-in pressure regulator valve assembly, four drop-in latch valves with springs, a converter feed priority valve kit, an anti back-flow valve kit, a high-pressure TCC regulator valve kit, heavy-duty solenoid retainers and a cooler flow by-pass delete. TransGo states the TCC lineup raises apply pressure by 15 percent for more holding capacity.
Several 10R80 shift complaints are fixed by software, a relearn or a hard part instead. Ford service bulletins on the Expedition and F-150 call for a PCM reprogram and adaptive relearn first, and some trace harsh shifts to a leaking CDF clutch cylinder sleeve. Sonnax also warns that a weak or recently discharged battery can make a healthy unit shift erratically until it relearns. Work through our 10R80 harsh or delayed shifts walkthrough and the 10R80 shift solenoid symptoms guide before pulling the valve body. A shift kit makes sense once updates are done, the battery and fluid level are verified, and the complaint still points to pressure control.
TransGo lists SK 10RL80-G1 for all Ford 10R60, 10R80 and 10R100 units and GM Gen 1 10L80 and 10L90. On the Ford side that covers the 10R80 in the 2017-up F-150, 2018-up Expedition, Navigator and Mustang, and 2019-up Ranger. Confirm the kit number on the box against SK 10RL80-G1 when it arrives, and send us your year and VIN if you want us to check your application first.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a boxed TransGo kit for the 10R80. TransGo's current kit for this transmission is SK 10RL80-G1. Check the label on the box when it arrives, and contact us if you need the kit number confirmed before ordering.
TransGo lists SK 10RL80-G1 for all Ford 10R60, 10R80 and 10R100 units, which covers the 10R80 in 2017-up F-150, 2018-up Expedition, Navigator and Mustang, and 2019-up Ranger.
TransGo's instructions include a section for installation with the transmission still in the vehicle. You still need to drop the pan and remove the valve body, so plan on fresh MERCON ULV.
This kit is built to correct pressure regulation and valve wear, not to add a hard shift feel. TransGo describes the result as cleaner, more consistent shifts with more TCC holding capacity.
Use MERCON ULV only. Ford's specification for the 10R80 is about 12.5 quarts on a complete fill. Check the level hot, avoid overfilling, and complete the adaptive learning drive cycle.
