**If you have the early model valvebody with the .420" bore, please see note at the bottom. **


Sonnax billet accumulators:  Replaces the plastic pistons, with upgraded billet pistons, moves the area of contact up and away from the original wear area. 


Transgo's Tuneless Shift kit:  Includes new thicker accumulator plate that will not flex, and new O/D tuff snap ring that will not break, HD O/D pressure plate for added clutches in the O/D pack (14 single sided clutches instead of 12), new steel self cleaning low/reverse switch valve, new thick valvebody gaskets, and triple layer separator plate, and springs and valves for the pump to allow for 200psi without a transmission tune.  **Removal of transmission is necessary for installation of this product**


DNJ billet channel casting:  The DNJ billet channel casting eliminates cross leaks by stopping the flex, and replaces the factory channel plate that is known to crack and cause premature O/D failure.  You have to stop the flex!

The bonded separator plate, or plate with gaskets, will not stop the factory channel casing from flexing, warping, and even cracking!


This plate is THE FIX for the 68RFE Transmission!




 We will refund you $50, for the .453" reamer kit, once the reamer is returned in good working condition.


**If your valvebody has a switch valve bore of .420", you must specify at checkout, because this kit will not work for you.  We can send you the .420" Transgo reamer kit, and you will also receive a refund of $50 when you return it in good working condition.
