Car acting crazy after paint job, please help! Options

[trdproven]

I just got my car back from my paint job. I noticed there was alot of dust from the overspray and all. However, when I turned on my car, my overdrive light keeps blinking. What is that?

Second, my miles per hour arrow goes crazy. Even if I just turn on my car the miles per hour goes from 0 - 60 back down to 0 then up to 140 then back down and then it does not move at all. My odometer, the one that counts each mile is moving by itself. I know my cluster was in good working condition. It also affected my transmission. My car will rev up high and the car won't move even with the car rolling, almost like the tranny isnt catching. So i started with L then moved my way up to 2 then back to drive, then it starts moving. but it seems like my car is downshifting almost like someone is turning off my overdrive.

Do you guys think that my intake or injectors got dirty from sucking in all that dust? Can I use injector cleaner?

Overall, this is a bad experience for me especially when all these things were working before I dropped it off. Maybe the body men were messing around with my car. I just hope someone out here can assist me figure this out. I'd appreciate alot.

Lesson #1 dont let friends work on your car, because there are always problems and you dont want to be the bad guy by asking them to make it right.

I know what you mean, but at the same time, the biggest concern of having your car being worked on is by someone you trust. I know he wouldn't do anything to it, it may be a bad luck of something or weird coincidence.

Anyways, my car has been working normally for the most part. yupp, for the most part. the trans still feels like it cannot shift on its own. I believe it is an electrical problem, because the body shop was working on the underhood. Not a mechanical/tranny, because when it works it does really work for a good distances. Do you guys think it may be the moisture of when they were wetsanding and prepping the hood? Thats the only explainable reason for me to believe it is maybe a wire or sensor. Could it be throttle sensor, speed sensor, tubes? still trying to figure it out but I can't cus when my car works normal, I don't know what to check. Most importantly, I can't find a consistent factor or variable when the car starts messing up, its almost random. If I could find that then I'm sure it will be solved.
