I'm having trouble with my car and wanted to see if anyone could help. The car displayed the code p0746 which is for the pressure control solenoid so I ordered the solenoid and replaced it on the valve body. When putting the valve body back in the transmission I made sure that the ratio control valve was connected the right way on the stepper motor and the pin that is at the top of the transmission. I put the valve body back together and added fluid but when I go to put the car into drive or reverse it does nothing but the rpms start spiking out of control when I press the gas, the car does not move anymore. Before I removed the valve body and replaced the solenoid the car would jerk when I accelerated but still drove. If anybody could help that would be great. Is there something that I have to reset after removing the valve body.

This could be a solenoid issue but more than likely this is a TCM issue.

However, we want to check and make sure the code is still the same.

Here is a guide that will help with this:

I am attaching the info below on the testing that we need to run through and the way to perform the line pressure test.

Please run through this and let us know what questions you have on this, and we can go from there. Thanks
