The Pressure Control Solenoid Valve regulates transmission line pressure. The PCM controls the PC solenoid valve based upon various inputs including throttle position, fluid temperature, MAP sensor, and gear state.

The transmissiom case side cover has to be removed to gain access to the PC solenoid valve, this is a labor intensive job.

I would tend to think not, it is a labor intensive job. Why do you question the PC solenoid valve, is there a DTC set?

The reason I question it is because kcusscam and I have been talking about it.
When I described the problem in my post he said he'd had the same problem and he believed that was what was wrong.

Is it something I can get by without doing for awhile??

I normally fix whatever is wrong with my car when it goes wrong but the 4 bills repair charge he spoke of scares me.

My car is driving fine, it just tweaks my melon that something is wrong with it.
My car is the other woman in my life

Anyhow thanks alot for your help Mark

Tim

Oh yeah there is no DTC set.

...
To loosen the bolts mentioned in 16 & 17 one has to remove the lower front splash shield.

Also nothing is said about the transmission to body frame mount. The two parts are held together by a single nut & gravity. Three bolts secure the transmission half to the side cover. One would think that that needs to be removed before unbolting the side cover.
