More Details About This Item :

Chrysler RFE transmissions have a special and unique,
full range pressure transducer and real-time adaptive closed-loop pressure control system.
Because of this, it is not possible to raise pressure in an RFE the same way you would in other transmissions.
The typical method of installing a stronger pressure regulator spring or larger boost valve will not work because,
the RFE control module will simply adapt and return pressure to OE specification.
An electrical booster option is the only way to raise pressure on an RFE.

This should deliver about 10 PSI Increase at lower pressure range and 18-24 PSI Increase At Higher Pressure Ranges.

This is a simple and affordable plug in line and go solution with no special tools.
