Transmission Problems? Ask a Mechanic for Answers ASAP
Hello, I'm Chris. Welcome and thanks for asking your question!
Will the vehicle roll in all gears other than park and will it not roll in park?
Thanks this verifies the shift linkage is connected and is moving the parts inside the transaxle, also verifies the CV joints are good. This leaves the pump pressure to low or zero. We need to check this with a line pressure test. If the pressure is low or none then the pump shaft has broken, or the pump has failed or the drive inside the converter that drives the pump has stripped. The next step will be removing the trans to check the converter and pump shaft, then the pump inspection if needed.
Below are the line pressure specs from Ford.
