This TransGo 722.6-A SHIFT KIT® Valve Body Repair Kit fits 1996 and newer Mercedes, Dodge, Chrysler, Sprinter, Jaguar, Porsche and Jeep vehicles with the 722.6, W5A-330, W5A-580 and NAG1 automatic transmission. Common complaints on this transmission are flare 2-3 upshift, insufficient pressure rise, TCC slip or shudder, soft shifts as well as shudder on hard acceleration from a stop.
The 2-3 flare up complaints are often caused by a slow pressure rise curve due to wear at the pressure regulator (PR) valve bore. Additionally, if any of the overlap regulator valve bushings are worn, this too can cause flare up complaints on any of the up or downshifts. The lube pressure regulator valve is another area of concern that has a two-fold effect when wear occurs. The first one is a loss of lubrication pressure and secondly it causes a loss in torque converter apply pressure. Also, the springs for the 2-3 shift pressure regulator and the control pressure regulator valve are prone to breaking.
Features & Benefits:
The kit includes a drop-in USA made hardened PR valve featuring longer lands which restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore. Similarly, the new drop-in lube regulator pressure valve system comprising of a bushing, valve, spring and sleeve will restore the system function using the existing worn bore. Additionally, the kit includes three new overlap valve bushings as well as a replacement springs for the two springs that often break in the valve body.

TransGo Shift Kit vs. Reprogramming Kit
Shift Kit® -- DESIGNED FOR DURABILITY
TransGo Shift Kit® valve body repair kits correct, prevent and reduce multiple transmission problems such as shift irregularities and durability issues. These kits are designed for normal everyday use and light duty towing.
Reprogramming Kit -- ENGINEERED FOR PERFORMANCE
TransGo Reprogramming Kit™ valve body performance kits are made for Heavy Duty and/or Performance applications, and include additional features such as:
Gear Command™: Allows full control of downshifting and will hold any gear to any RPM. Retains automatic up shifts in the drive position. Certain units allow manual up shifts on driver command.
Manual Shift Control: This feature fully converts the valve body to manual/stick shift operation – no automatic shifts. Most Manual Shift Control kits also allow you the ability to easily convert back to automatic.
Tuneless: Patent-pending internal calibration technology “tuneless” allows install without the need for additional transmission tuning software or programmers.
Was ist ein Schaltungssatz?
TransGo Shift Kit® Ventilkörper-Reparatursätze sind eine Kombination aus neuen und überarbeiteten Komponenten, die hauptsächlich im Ventilkörper, manchmal aber auch in der Pumpe oder sogar im Getriebe selbst eingebaut werden. Diese Kits beheben eine Vielzahl von typischen Problemen und Schwachstellen, die sich je nach Getriebemodell unterscheiden, wie z. B. die üblichen Verformungen und Abnutzungserscheinungen, und ermöglichen oft, dass ein Getriebe mit höherer Laufleistung besser funktioniert als ein neues. Typische Bestandteile eines Ventilkörper-Reparatursatzes sind Federn, Ventile, Rückschlagkugeln, Dichtungen, Trennplatten, etc..
