Many years back we (circa 2014) RevMax began using billet valve bodies in their 68RFE 1000 series transmissions. These units featured on demand lockup and the rigidity of a billet channel casting. These were offered for a short time by us but the market was not yet open to paying for what was thought to be an unneeded and expensive item. We stopped selling this an option in 2015 and mothballed the project.
When we began to make big power without 68RFE we began to use the billet lockup valve body again. This unit was installed in our 2017 and 2018 UCC race truck and was the center point of our 10.29 ET and one of the reasons we were able to complete all weekend and drive to and from the event over 800 miles without ever touching the transmission at over 1200hp!
Sometime after the 2018 UCC other companies began marketing a billet channel plate for sale. Initially, we dismissed the idea of re-releasing our billet valve body but customers have demanded that we bring it back. This valve body is available with or without the on-demand manual lockup option! Unlike other designs, we have full depth worm tracks in crucial circuits. The other designs we have seen have only a .190” deep worm track in a very critical circuit. This circuit is responsible for venting of the critical SSV valve and should not have been restricted. With the other design, they decided to shallow out ALL of the worm tracks so that it would work with a factory pan. While this made it more appealing to the masses, it meant that they were unable to keep the factory worm track depth in these critical areas. Due to our superior design, which made no compromises to appeal to the masses, the use of our deep pan or others is required. The stock pan simply is not deep enough.
We have tested our ZeroFlex valve body with the following aftermarket pans and this is what we have found in regards to fitment. Be sure to check your pan closely for clearance as this information is just a guide.
AFE Power: Due to the shallow depth of this pan you must remove the tall filter support fin in the pan and use a stock 2WD filter. Transtar part #A72010B
BD Diesel: Fits with the stock 4×4 filter as is, no modifications required.
Mag-Hytec: Due to the shallow depth of this pan you must remove the tall filter support fin in the pan and use a stock 2WD filter. Transtar part #A72010B
ATS Diesel: Does not fit due to the excessively thick sidewalls of the pan.
PML: Fits with the stock 4×4 filter as is, no modifications required.
Revmax: Fits with the stock 4×4 filter as is, no modifications required.
We highly recommend using one of our bonded separator plates in conjunction with this channel plate. The bonded plate will allow the user to run up to 250psi of pressure without any pump modifications! These can be purchased from Transtar, WIT, NatPro and many other local transmission part suppliers.
