Hey Guys,
Was pulling into work today and transmission went caput. Ran my codes and got P0700, P0876, & P0944. Just got home and doing my research. So, far I'm hearing it might be my Pressure Solenoid, Pressure Sensor, and whatever "Loss of Prime" means.
Any insight is greatly appreciated. Thanks in advance!
Loss of prime means, either you have a leak and the fluid is too low to engage. Or the transmission front pump has failed. Do you know if the transmission is a 42RLE?
First thing I would do, is hook up a 300 psi gauge into the line pressure port and post the readings. That will let you know if you have line pressure.
