Chrysler's RFE family of rear wheel drive transmissions do not offer a tap to check main line pressure.  To remedy this, we offer our RFE Gauge kit to allow you to tap into the port where the main line pressure sensor sits while keeping the sensor in the circuit.  Our tool allows you to position the adaptor block in multiple locations to clear whatever obstructions (exhaust, heat shields, etc.) may be in your way.

​

The RFE Gauge kit contains everything (minus basic hand tools) necessary to connect an 1/8" NPT gauge to an RFE style transmission.  The RFE Gauge kit does not belong to any series, as it is not a servo bore kit.
