1999 plymouth voyager water in trani fluid

Hi and thank you for any help you may be. In short I was driving down the road when the car over heated. I found a water oil mix in the over flow reserve. I checked my oil it was fine ... I checked my tranifluid and found a mix of water in it.... could this be a seal or som thing like that? and where may I find a repair manuale to look at on line for free... Dillon

    99 voyager overheated coolant mixed with trans, trans fluid mixed with coolant and the water pump seems to be making a noise now too. Also my power steering fluid got forced out the unit.

    It is doubtful that there would be a mix of trani oil and water. I have read that there could be a leak of engine oil in the water cause by camshaft sensor. Anyone else know of this?

Your radiator has another little radiator inside the main radiator this is called transmission cooler seems to be than the cooler has a hole or is broken the main reason for this to happend is becasue the antifreeze or coolant is not been serviced at least every 50k miles or when you mix wo diferent coolants like diferent colors they get contaminated and create acids and start corrosion in the coolant system have the radiator replaced and flush the cooling system wiht lost of water then add only the designated antifreeze on greeen coolant 50/50 mix they sell it allready mix but if you but the one is not mix mix it with 50/50 coolant and destilated water but i recomend to buy 50/50/ green coolant

Mopar minivans have a habit of the tranny cooler in the radiator rupturing and letting coolant into the tranny. Sometimes tranny performance can be affected. A simple solution is an aftermarket tranny cooler. That is very quick and a lot less expensive than a new radiator.

My plymouth, voyager turns off while I'm driving it down the road..

Just an Idea. When it dies next time check the relay temperatures, if you can. Once I had a fan relay which would over heat and the radiator fan would not work. After relay cooled down it would work(This usually happened when I was stuck in traffic). Could be a fuel pump relay. If relay is a lot hotter than the other relay could be bad relay. My thought is it will not cost you anything to try it. I think it may be something electrical over heating. 30 years ago my thought would have been the coil, when the coil started going bad it would heat up and the car would die till it cooled off.

Stop driving it.
Have it diagnosed and properly repaired.
I tell you this having, owned a trans shop, and 50% of my work,sadly, was from your Mitsubishi Transaxles, all in caravans.
Don't have all night to get technical.
If you already had slipping,get your check book ready.
I don't want to be hurtful here, but I would sell it and any other van type vehicle. That way you won't have all the trans issues and If you ever get in an accident,you'll most likely ruin your quality of life
My last ride in one of those was 1998. I refuse the get in one. Look at the govt crash tests. Scared me for life,and I used to road test them a lot in my own business.
You have electrical/electronic control issues.

Slow Leak in Water Pump-1999 Plymouth Voyager

What's probably happening is the weep hole on the water pump is leaking water. The weep hole is a warning sign that the water pump needs replaced. You don't have any heat because the impeller in the water pump is no longer circulating water.
