Sounds like you lost fluid pressure in the trans. Was there a code named "Loss Of Prime" Does it makes a whizzing noise while it slips?

 

no code for loss of prime, it does make a whizzzing sound when it slips.

 

what needs to be done if loss of prime?

 

code p0734 gear 4 incorrect ratio, p0732 gear 2 incorrect ratio, p1781 pressure switch circuit 0D, p1782 pressure switch circuit 2-4, p1784 pressure switch circuit LR, p0700 transmission control system MIL request.

what do i need to do with this problem ?

 

If you don't get an answer here head over to DodgeForum.com or The Chrysler Minivan Fan Club . There are several tranny techs on the forums.

 

The whizzing is usually indicative of torque converter malfunction from loss of fluid pressure. It means a rebuild....probably. First thing I would (that you can do yourself) is drop the pan and see if there is any metal in there. Then you will have no doubt.

 

where do I check manually the oil pressure on a 3.3 engine in a 2000 Chrysler town & country?

 

One assumes you've checked for loss of ATF fluid, i.e. correct on the dipstick under conditions as outlined?
