Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
That could be an internal valve problem, however, you may want to try the input speed sensor, as there has been a service bulletin on them with an updated part. Here is what it states.
DATE: Jun. 30, 1995
SYMPTOM/CONDITION:Transaxle in limp-in condition due to intermittent transaxle input speed sensor signal.
DIAGNOSIS:Using the Mopar Diagnostic System (MDS) or the Scan Tool (DRB III) with the appropriate Diagnostic Procedure Manual, verify all engine/transmission systems are functioning as designed. Test drive the vehicle throughout the transaxle operating temperature range. With the DRB III in the RPM Display Mode under Transmission Systems, monitor the Input (Turbine) Speed Sensor Signal. If the Input (Turbine) Speed Sensor Signal drops to 0 RPM and is accompanied by any of the following Diagnostic Trouble Codes (DTC's) 36, 50, 51, 52, 53, 54, 55, or 56 perform the Repair Procedure of this bulletin.

FAILURE CODE: PS - New Part
Yes that is for a 96 T&C. The input speed sensor is the one onthe left in the picture. Front of the vehicle on the left side of the trans.
I don't know about the got paid twice thing, I see $23 on this end. The valve body should come right out. Let me give you the steps that I have.
Push Park Rollers From Guide Bracket
NOTE: To ease installation of the valve body, turn the manual valve lever fully clockwise.
Installation To install valve body, reverse removal procedure.CAUTION: The valve body manual shaft pilot may distort and bind the manual valve if the valve body is mishandled or dropped.NOTE: To ease installation of the valve body, turn the manual valve lever fully clockwise.Guide park rod rollers into guide bracket, while shifting manual lever assembly out of the installation position.
That's all the information that I have on it. Let me opt out and we can relist the case to see if there may be another expert who may have more about it. Thank you for your patience.
