about 2 weeks ago i was working on local ranch, we got 2 inches of rain over night and i had pull a stock trailer through canyons full of mud and running water. after that my 02 dura/allison chevy has been acting up. the shift indicator quit working, so u cant tell what gear you are in, i shift it into park and the door locks dont unlock, the automatic lights quit working. today i took my truck to the carwash and washed all of the mud off of it, got in and now the service engine soon light is staying on. Ne body got ne suggestions? i really hate to take it to the dealership, so ne help would be appreciated.

Sounds like maybe some water got into the nsbu switsh on the trans, this should control all the functions you are talking about! as for the check engine light it could be related or it could not be, its hard to say. Are there any other problems?

MAybe Mike L will chime in he would know better if this is the posiable cause?

well i ended up having to take it to the dealership, it got to where third gear was the highest gear it would go into. They put in what they called a prndL switch, i picked it up today and it is running good as new, even though it cost 200 bucks, im half tempted to sell it and keep the ole 97 stroke.
