Question about 2005 Dodge Neon

2003 Dodge Neon SE the car acted like it was in neutal

The transmission cooler blew up and put the transmission fluid in the engine cooling system and engine coolant in the transmission fluid. This is a Dodge Neon 2003 SE. What happen was the car started to smoke then I turned a corner and the car acted like it was in neutal. Now the dealership is quoting me some ungodly amount. They want to change to cooler and completely rebuild the transmission. Does this sound right?

As detrimental as coolant is in the engine oil, it has a much worse affect in the transmission fluid as its a thinner fluid and does not have the additive package that a motor oil does.

Here's how I would approach this:

To replace the cooler (its probably in the radiator) means they will likely have to replace the radiator and then the rebuild of the transmission is going to be up there as well. So all this is going to be considerably expensive.

You could go that route if you wish, but you could also take a chance and have an after market transmission cooler installed (by-pass the one in the radiator completely so you dont have the risk of coolant in your transmission again) and then have a thorough transmission flush done with a new filter installed.

Now, you are likely looking at a few hundred dollars minimum if you have the dealership do this but Im thinking that the reason the car acted like it was in neutral was due to the lack of transmission fluid because of the cooler line busting.

If you can do this work yourself you could probably do it all for less than $200 and if everything works out and the transmission is not damaged and works properly, you've saved yourself a good chunk of change. If it doesnt work and continues to have problems, then you can decide if the repair bill will be worth it to rebuild the transmission.

The key think here will be doing a very thorough transmission flush to get any traces of coolant out of the system and a new filter. Hope this helps.

Try having a radiator shop look at the transmission cooler inside the radiator to see if it can be repaired. If not, then a new radiator is needed.

I have a 2003 Dodge neon car gave me no indication it just quit pulling all of a sudden. Noticed radiator fluid in my transmission by looking at the dipstick. So I was toled my trans cooler has gone bad....

This is the best way to proceed. You can only hope that nothing was damaged in the transmission. The only way to tell is to drive it and see, unless you want to take it to a transmission shop and let them tear it open and have a look. It's quite possible that you did no damage to the transmission, just had the wrong fliud to keep pressures where they need to be for driving. No one can tell you for sure what will happen next, keep your fingers crossed and hope for the best. I would probably do at least 2 fluishes to make sure nothing got left behind and while you at it change the filter.

Would the engine over heating on my 2002 dodge neon cause my transmition to slip?

No, this is not related. You just happen to lucky enough to have two problems at the same time. If the engine got to a point where is was glowing hot, it could transfer the heat to the cooling lines causing air bubbles in the fluid and henceforth a slipping tranny. However, your engine would seize solid forever given those circumstances.
