Reman vs. Rebuilt 6L80 Valve Body?
Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value.
Reman vs. Used 6L80 Valve Body?
Buying a used 6L80 is risky and many do not have any warranty so they have a much higher chance of failure and losing the fluid cost and labor time when reinstalled again.

6L80/90 Applications:

The 6L80 (and similar 6L90) was introduced in late 2005 and is a fully automatic, six-speed, clutch-to-clutch, rearwheel drive, electronic-controlled transmission. The transmission consists primarily of a four-element torque converter, an integral fluid pump and converter housing, a single and double planetary gear set, friction and mechanical clutch assemblies, and a hydraulic pressurization and control system. The four-element torque converter contains a pump, a turbine, a pressure plate splined to the turbine, and a stator assembly.

The torque converter acts as a fluid coupling to smoothly transmit power from the engine to the transmission. It also hydraulically provides additional torque multiplication when required. The pressure plate, when applied, provides a mechanical "direct drive" coupling of the engine to the transmission. The planetary gear sets provide the six forward gear ratios and reverse. Changing gear ratios is fully automatic and is accomplished through the use of a Transmission Control Module (TCM) located inside the transmission. The TCM receives and monitors various electronic sensor inputs and uses this information to shift the transmission at the optimum time. It features clutch to clutch shifting, eliminating the one-way clutches used on older transmission designs.

6L80/90 History:

There are many calibrations of the 6L80/6L90 valve body, we require your VIN# in order to calibrate.

Only certain valve bodies will interchange with others, which is why we ask for your 17-digit VIN# when you order so we are 100% sure it is the matching unit for your vehicle!
