The 68RFE pump was the first problematic area that we addressed. Our engineers were able to determine the amount of clamping force needed to make the clutches hold. Unfortunately, the factory configuration is not capable of achieving this. Let's take a quick look at some key issues addressed:

From the factory, the 68RFE transmission pump is incapable of exceeding line pressures of 170 PSI. Many times, we see tuners request from the transmissions lines pressures in excess of 200psi, which the factory pump is unable to achieve. In all forward gears, the factory pump bleeds off pressure at 165 PSI. This is done by design. When a vehicle is heavily modified (i.e. larger wheels and tires, aftermarket turbos, tuners) the line pressure becomes critical to keep the transmission alive.

The 68-SCP from SunCoast addresses this issue. When combined with our custom 68RFE separator plate and our Custom PR Valve, this pump half will allow you to achieve pressures in excess of 250 PSI. Another issue plaguing the 68RFE is the torque converter circuit within the pump. This issue often leads to the ballooning of the torque converter. Here at SunCoast, we address this issue by modifying the release oil circuit within the pump.

Furthermore, each 68-SCP is vacuum-tested to ensure no cross leaks are present. This modified pump half fits all 68RFE transmissions.
