" RFE " Remanufactured Transmission Valve Body
Complete Unit Solenoid Without Solenoid Block Fits 1999 To 2008

High Quality Updated, Assured, Tested & Lifetime Warranty Product !

The Most Common Reason A Valve Body Is Needed On These Trucks
Chrysler transmissions cause bore wear as they oscillate and stroke during operation.
This wear allows pressure loss and cross-leakage, and often permits the plugs to cock and hang up in the bore.
This can result in failsafe ( Safe Mode ), various codes, bind-ups, and burnt overdrive or 4th clutches.
* Solenoid Switch Valve Is Binding & Valve Body Bore Is Worn Out, Requires Oversize Valve & Machining Process *

** Keep In Mind The Updated Solenoid Block Should Be Installed In ALL These Trucks **

I Am Mechanically Inclined And I Do My Own Maintenance
I Love My Truck & Plan To Keep It More Than 6 To 8 Months
I Don't Have The Special Tools, Reamers, Or Knowledge To Oversize The Bores My Self

This Fits All Below Automatic Applications Within This Year Range

Specific Details About How & Why These Need Replacement

As these models accumulate more and more miles, the internal aluminum castings begin to show signs of wear.
The valve inside the casting stroke hundred of times a day during driving.
This movement and heat causes the aluminum casting bore that supports valves to weaken.
This scoring in the valve bore causes pressure loss, soft shifts, at times even shift related check engine codes.
The repair on these entails maching the bores larger and installing oversized valves.

With these special rebuilding steps, and tooling this wear can be corrected.
These steps can help all the shift functions; allowing the vehicle to perform like new again.
