How do I take the vavle body cover off a 2010 dodge caravan with a 41te Trans 3.8l engine .

Although the transmission may be siilar, the engine and supporting wiring harness, and control modules are not. This can be done, anything can, but it is probably more trouble than it's worth for a mini van. If this was a classic car then sure.

Check front stabilizer bar bushings.

The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.

The code is about the switch that monitors the hydraulic pressure for operating the low/reverse clutch of the transmission. That clutch is called into play for all forward gears as well as reverse, so it seems reasonable if that clutch were not working that the car wouldn't move in any gear. I would begin by making sure that there is sufficient trans fluid by inspecting its dipstick. If needed only use ATF +4 but don't overfill it. Also, just on a chance, take a look underneath to see if you see any motion of either the left or right half axles (or one moving, but one not) which would be another reason for no motion due to a drive shaft disconnection or some such anomaly. Other than that, your problem could be with the Low/Reverse solenoid switch in the solenoid pack portion of the transmission (the box on the driver's side of the trans) being stuck. That can be repaired without removing and rebuilding the transmission so let us hope that may be the cause. I would have the car towed to a good independent trans shop that has a reputation for knowing how to service the Chrysler electronic transmission.

Hope this helps.

Replace the transaxle or see if it can be rebuilt. Those transaxles have incorporated electronic solenoids that can fail causing the codes to appear as you described. One thing you might check prior to getting it rebuilt or replaced is have the computer checked and check all of your wiring connections. Anytime you have a wiring connector on the exterior of the vehicle you can get corrosion issues it may be simply cleaning the connectors, placing dielectric grease on them and reattaching. Before cleaning any connectors always disconnect the negative battery terminal.
