Our All Inclusive Bundle Features The Most Commonly Needed Items For This Repair !

Our Kit Features the most up to date solenoid pack / block available on the market today !
This is the updated white connector design with the included detent plate this allows our kit to fit all models.
Black Connector models are 1999 - 2003 models and Must Be Updated with the white connector solenoid asm.

This Kit Features a Neoprene Rubber pan gasket which insures a more effective seal free of leaks.
This gasket's bolt holes are also designed to hold the pan bolts in place during re-assembly.
Also we have found unlike the factory using only RTV for the pan seal.
A fixed gasket creates a much better seal over RTV only.
You Can still also use RTV in some points if needed / preferred.
This is an Easy replacement with the transmission still in the truck.
     Requires removal of transmission pan and the valve body.

Tech Tip:
Besure to unplug the main solenoid connector before dropping the valve body down.
This is retained by two flip latches, one outer edge and one inside edge.
Don't forget to plug this back in after the repair is complete.

The external connector repair kit is not yet available.
Solenoid is mounted on the Top side of the Valve Body Assembly.
These solenoids ALWAYS come charged with residual fluid left from the dyno testing process.
The manufacturer Always dyno tests these to make sure they work correctly before releasing to the distribution market.

Excellent Kit
Willard Miller (Nottingham, PA) 6/22/2017 2:08 PM
This kit fixed my 2004 Jeep Grand Cherokee 4.7HO that was kicking out a Shift Solenoid A fail code. Easy install, Video's were good, ability to print step by step instructions with Pics and Torque values would be better.
