so i am asking could this be a computer issue... how can i check it..
battery issue.. did not have time to check fluid in tranny... or is the tranny shot if so live in Ohio if you know a good place do get a tranny please list it. something beefed up would be good like to hit corners more than straights. thanks again

well, it seams like you did the right things about letting the car dry out. However I think that once wet, all the ground points have corroded and rusted over. I'd start with that first, and clean each and every one of them. You can look in the tech section in the electric problem sticky and they have a diagram of all the ground points on the car. I guess start with that, and let us know if anything changes

You make no mention of trying to actually take things apart and drying them out(fuse box,bcm etc) if you just left the car sit,you will now have never ending electrical problems.

agree Antonio... start checking the grounds. Chances are the PCM may have gotten wet internally. Check the passenger sidefoot well PCM also. My PCM got wet in there from that lovely A/C drain that GM never cut and mine did the same thing.

Drove fine, threw a bunch of codes. Turned the car off and BAM she was dead. What really sux is if you get a new PCM the dealership will have to flash it to match it to the BCM and they will put a stock 2000 tune in the car. So keep that in mind also, you will have to contact a tuner or purchase a tuning software to get a S/C tune back in the car.

Hello, Thanks for your help great place to start I will post how it goes as soon as I get some progress. Also C5kid when you say yours did the same did you mean the tranny acted up too? Thanks again!!!!!

C5kid

no I was takling about the PCM throwing all those codes and crap. Any water on those PCM's creates a nightmare.

Ok so I eneded up taking the car to a shop were they pulled apart the fuse box, and computer went over the wiring cleaned all the corrison said that's all good now but it will not shift in to 3rd or 4th still the said they are not tranny specialist but they think its internal and said to have it checked.could the wreck or water caused something to fail if so insurance will have to pay for it. But if not I will I can get a reman tranny for 1500 bucks.or do I have a shot of it being fixable if so any ideas what its doing or what could of caused it. Thanks
