I have a 03 dodge grand caravan 3.3L i hit a puddle of water a few days ago 2 days later when slowing down from 3rd to 2nd gear around 35-20mph the car jerks other than that it shifts fine what could do this? i cleaned out the plug going to the transmission computer even unhooking the battery for 1 day no difference.

 

anyone ?

 

Are you saying that the van had always been shifting perfectly all the time, then you hit the puddle, and 2 days later the downshift jerking started? If so, I can't make a connection between those 2 things. How many miles on it? Any towing or mountain driving? Have you ever put transmission additives in, used any fluid other than ATF+4, or had a power flush done. Any drips from underneath, and have you checked the fluid level and quality?

 

Yes after i hit the water 2 days later it started it always shifted perfectly just hit 80k no towing or mountain driving no transmission additives and i have only changed the transmission fluid once and that was a few years ago and yes it was atf4 the fluid does not look or smell burnt it just randomly started happening.

 

anyone else? called the dealer they have no idea what i am talking about doesn't surprise me...

 

how big was this puddle? Have you checked the fluid since to make sure it wasn't contaminated with water?

 

it was about 2 inches deep and yes fluid looks fine i see some people calling this Bump Shift? but no real answer on how to fix it also there is no engine or warning lights.

 

honestly 2 in. of water isnt really that significant. The issue starting after the puddle may be a coincidence. If it happened right after the water then maybe, but 2 days later, I'm not entirely sure it's related.

 

I've read a few different accounts of "jerking" in the 4 gens, mainly during downshifting. But most of those were describing a chronic condiditon, and none of them mentioned a specific event causing it to begin. I remember some of these guys doing LOTS of things trying to fix it, including one guy who installed a new tranmission (with no success). So IDK how much you're going to be able to do about this. But if the water splashing around really did cause it, then I think it could only be electrical in nature. The things that come to mind are the input/output sensor and solenoid connections. Can't tell you why or how water could get into one of those units, but likely could cause a problem like this if it did.

 

Ok even if its not the water that caused this and it is a coincidence What else would do this? I saw 1 person who changed the whole module but it it came back a week later I just dont get how this randomly started happening it only has 80,000 miles on it.I just dont want to damage the transmission if it is going to keep doing this.
