68RFE Transmission Valve Body Accumulator Upgrades Fundamentals 2019+

RevMax 68RFE Valve Body ZeroFlex Billet Channel Plate V2.0

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 as an option in 2015 and mothballed the project.

Our initial 1” solid version was a game changer. It gave the market what they asked for—a perfectly flat, rigid and smooth surface finish. As great as it was, it did have a drawback, as it could not be used with some aftermarket pans or with any stock pans. Customers have commented that they wanted a new design channel plate that incorporated all of the initial designs’ features yet allowed it to be used with a stock pan or with any aftermarket pan. After nearly 8 months and 6 revisions we now have the V2.0 available!

Our V2.0 still is 1” thick but this new version has precision cutouts that allow the use of a stock filter and pan. Unlike other designs, we still have full depth worm tracks in crucial circuits. The other designs we have seen have only a .190” deep worm track in several critical circuits. One restricted circuit is the combined vent track. This track is responsible for all venting operations and in particular the problematic SSV valve. The next restricted circuit is the torque converter clutch signal circuit. Restrictions in this circuit create all kinds of torque converter related concerns including: dragging when coming to a stop, overheating, soft or harsh TCC apply or release, and back feed issues resulting in P1776 and P0871 trouble codes. Both our original and V2.0 have nearly full depth worm tracks in these areas which eliminate these issues!

Our V2.0 plate will work with ANY aftermarket transmission pan as well as with stock transmission pans. There is no need to alter any part of the pan or use any special filters. Just install it like you would a stock channel plate and go!

Sonnax 44892-01K Accumulator Cover Plate Upgrade Kit

The accumulator plate in Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE units is weak and not held securely enough to withstand the impact of the accumulator pistons. The OE plate flexes, causing the screws to loosen and break.

Sonnax accumulator cover plate kit 44892-01K is an upgrade over the OE plate and allows salvage of valve bodies with damaged plates. The patented plate is made of thicker steel and has three additional screw holes to hold the plate more securely.

• Accumulator Plate
• Accumulator Shim
• Screws (6)
• Washers (6)
