Many times, we see tuners request from the transmissions lines pressures in excess of 200psi, which the factory pump is unable to achieve. Pressure Related ATF Leaks occur when the engine is running and fluid pressure is built up inside the transmission. The modern Mini Cooper has a low pressure fuel pump in the fuel tank that moves the fuel to the motor, but it is the high pressure fuel pump (HPFP) under the bonnet which delivers the pressure the fuel injection system needs. This causes the unloading spool valve to shift to the right, allowing the constant flow of oil to be dumped to the reservoir at a relative low pressure value. L here is the abbreviation for Low. The transmission oil pressure switch is unique in that its sole purpose is to collect data about the pressure found inside the transmission case, which impacts the timing and operation of shifting a vehicle to a higher or lower gear if needed. All Cat water pumps are easy to maintain, and cat pumps are designed to be user-friendly and to make regular maintenance as easy as possible. Often, the refrigeration equipment is still running, but the product temperature is suffering about 7 to 10°F. You can be methodical and cover all the bases during a rebuild and still things can go wrong. Pump sizes The automatic transmission models have been test fit with 17 GPM rated size single pumps and tandem 11 GPM rated pumps. This is for your Dodge Cummins Turbo diesel truck with a Bosch VP44 injection pump. Our specialty is in diesel transfer as well as heavier liquids like oils and motor oils.
