Product Description
Transmission Shift Kit® GEN1
Fits: 6R60, 6R75, 6R80 GEN1 2006-on
Also fits ZF6HP 19/26/32 GEN1 2003-on
Does Not Fit: ZF6HP 21/28/34 GEN2
This 6R80 Shift Kit fits 2006-14 Ford vehicles equipped with a GEN1 6R60, 6R75 and 6R80 transmission, as well as 2003-up BMW, Audi, VW, Aston Martin, Rolls-Royce Maserati, Hyundai, Kia and Jaguars vehicles equipped with ZF6HP19, ZF6HP26 and ZF6HP32 GEN1 valve body. This kit does not fit ZF6HP21, ZF6HP28 or ZF6HP34 with a GEN2 valve body.
Common concerns with this transmission are TCC shudder, rough coast down shifts, gear ratio error and solenoid performance codes. Firstly, these complaints are the result of the wear in the pressure regulator (PR) valve bore and the pressure regulator valve balance bushing. Secondly, the torque converter clutch regulator valve design and calibration were in dire need of an upgrade to address the TCC shudder complaint.
Features and Benefits
This TransGo Shift Kit includes a hardened steel drop-in two-piece pressure regulator and a redesigned TCC regulator valves for a quick no-hassle install. Our drop in valves require no reaming or tooling.
Both the redesigned drop-in steel PR valve and TCC regulator valve, feature longer lands which restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore. Furthermore, the longer lands increase bore longevity by redistributing the load over a greater surface area. The kit also includes new rubber dampener inserts that flatten out over time and new wire retainer clips to replace the occasional broken one.

For High Mileage Vehicles
If you have a valve body with a lot of miles on it, you may still get a persistent coast-down clunk or slip-sliding shifts when hot. Those valve bodies will need to have the solenoid regulator and lube regulator bores reamed in order to fully restore the hydraulic integrity of the circuits. Consequently, TransGo offers two kits to do it, one with tools and one without. The kit with tools includes two guides and a reamer that can be used on both bores, if you already have the tools, you can buy just the valves and springs.
