Description

2007.5-2018 Ram 2500 & 3500 6.7L Cummins RevMax 68RFE Zero Flex Billet Transmission Pump Body Features:

RevMax has always wondered why so much attention has been paid to the warpage of the valve body on the 68RFE and none to the pump! Transmission builders across the country (those that have access to surface plates) have known for years that the 68RFE pump is prone to warpage. Just like the valve body, the pump too doesn’t have a gasket and relies on perfectly flat mating surfaces to seal properly. When the pump is new these surfaces seal pretty good but after hundreds or thousands of heat cycles warpage becomes a huge issue. RevMax has seen used pump bodies with up to .020” warpage and nearly every pump we inspect has a moderate amount.

Warped pump bodies can give a wide range of failures or complaints including:

Erratic actual line pressure, especially on trucks running additional line pressure.
Unexplained Overdrive Clutch failure
Unexplained Underdrive Clutch failure
Increased transmission operating temperatures
Gauling of the pump separator plate
Excessive pump gear wear
Damaged pump body at the gear face location
Pump seal failure
P0868, P0933,P0934 loss of transmission prime, low line pressure or high line pressure
P0740, Converter dragging or staying engaged when coming to a stop

Some builders have thought they had a solution to this issue. They have attempted to resurface the pump body by flat sanding or stoning it. This absolutely will make it flat again but it causes another bigger issue. By sanding down the pump body you also decrease the clearance from the pump separator plate to the top of the pump gears. A new factory pump has .002-.003” clearance in this area. Considering that most pump bodies have over .005” warpage this means that by the time the resurfacing has taken place the gears are now in constant contact if not binding against the separator plate. This decreases pump life and will contribute to previously undiagnosed transmission failure. The good news is the stator half of the pump can be conventionally resurfaced and be reused so long as the valve train has been inspected to make sure excess wear isn’t observed. RevMax's pump body will work with any new, used or rebuild pump stator assembly. This body can be used on stock 68RFE’s and with any brand aftermarket 68RFE. It is also highly advised to replace your used pump separator plate with our coated version or a new OEM plate.

The RevMax 68RFE ZeroFlex Billet Transmission Oil Pump Body should be deemed an essential minimum part on even a stock 68RFE rebuild. It has many features that the factory part even when new does not.
