So how do the brakes and clutches move to change gears? Well, the torque converter is also in charge of driving the transmission fluid pump. The fluid pressure is what activates clutches and brakes in the planetary gearset. The pump is often a (a gear pump) meaning that a rotor spins in a pump housing and as it spins, it "meshes" with the housing. This "meshing" creates chambers that change in volume. When the volume increases, a vacuum is created- this is the pump inlet. When the volume decreases, the fluid is compressed or pumped by the meshing of the gears- this is the pump exit. A hydraulic control unit sends hydraulic signals to change gears (via band brakes and clutches) and to lock the torque converter.
Every so often, I am getting a P2797 check-engine error code, which indicates something with the Auxiliary Transmission Fluid Pump.
Any idea on where/how to check the fluid level?
Sometimes when the Hybrid is wanting to kick into completely electric mode, the car feels like it "stalls" (vehicle slows way down as I'm pressing on the gas) and then the gas engine kicks in and it moves forward just fine...so guessing that the hybrid/electrical transmission didn't quite "get in gear" (so guessing code = check fluid for that tranny)...
Anyone have counsel??
