I have a 97 grand voyager. I blew the tranny about 3 years ago. I took it in for a flush & they replaced it with the wrong fluid. After replacing the tranny, the guys at the garage told me it took a special kind of fluid. Regular tranny fluid isn't good for it. Hopefully this helps.

Hey luocifer,
You blew the trans fluid cooler in the radiator, and now coolant has mixed w/ tranny fluid and it gets worse (sorry!) coolant will severely damage the internals of your transmission (ie friction discs etc .....) wish I had some better news for ya. You can try to get the trans flushed after you make the repairs, but its only a matter of time before the tranny completely fails .... I recommend replacing the radiator and a transmission rebuild. A used tranny is another option but I never recommend it ( had too many junkyard tranny nightmares)!

Suggested Repair

Replace the radiator, which contains the transmission cooler that failed and mixed coolant with transmission fluid. Flush the transmission after repairs, but plan on a transmission rebuild because coolant damages the friction discs and other internals. A used transmission is a less reliable option.

Conversation Summary

A 1997 Plymouth Voyager with about 122,500 miles and a transmission rebuilt in 2005 began refusing to shift, then overheated. The transmission fluid and coolant became the same color and smelled like chocolate milk. Another owner noted that this transmission needs a special fluid. The expert said the transmission cooler in the radiator failed, allowing coolant to mix with transmission fluid and damage the transmission. Recommended repairs are a new radiator and a transmission rebuild after flushing; a used transmission was not recommended.
