98 T&C Transmission Code advice

[Gazer]

We were driving our T&C on the free way. Tapped the brakes to see if the roads were ice and the engine reved up. It was as if the engine was not connected to the transmission. Long story short it went into limp home mode. OBD codes are as follows:

P1765 Switched Battery Failure
P1732 UD Pressure Switch Circuit
P1727 4C Hydraulic Pressure Switch CKT

LR Clutch 51
OD Clutch 89
24 Clutch 53
UD Clutch 59


Any suggestions? Can you tell me what these mean? Any help greatly appreciated!

okay the 1765 code means. an open or shorted condition is detected in the trans relay control circut, this relay supplies power to the TCC. no codes in my book for the others sorry

I have tried different relays, but didn't change anything. If the weather warms up I may start to try to go through the wiring. Thanks for your thoughts!

I have tried to find definitions for these, mainly 1732 and 1727 but no luck, will probably call dealer tomorrow and ask. I am wondering if 1765 may have set 1732, and 1727, off being it is a 12 volt circuit error.

I checked the continuity between the wiring harness plug at the transmission and the plug at the TCM. Every thing checked out ok. It has 196000 miles on it. So I am ready to give up on it. My wife loves this van and is begging me to go ahead and put a transmission and a engine in it. Oh the things we do for love. Maybe when spring comes I will tackle it.
