Engine/Tranny Compatability

Just curious of some engine and transmission compatabilities between different years of Dodge Caravans/Voyageurs.

Can a 1990 3.0 L engine and tranny fit a 1991?

Can the 3 speed Caravan tranny replace a 4 speed?

Can a 3.3 L Caravan engine replace a 3.0 L?

Thanks to anyone who can answer even one Q.

Yes........

Maybe.....dependant on electronics....

Yes, physically, but electronics and harnesses are VERY different...And usually not even close to worth the aggravation or expense..

I've been told that some auto recyclers have books that tell them what & if different years are compatible ? Might be worth a call ?

Yes it does fit

Can the 3 speed Caravan tranny replace a 4 speed?
No, it will not work, the 3speed has different bell housing (mounting to engine is totally different, also 4 speed is computer controlled and 3 speed is not.

Can a 3.3 L Caravan engine replace a 3.0 L?
No, two totally different engines.

Has mentioned before, salvage yards have books and software info that can tell you what years fit what.

Good luck,

Fred.

Wow thanks for the details guys.

See, I'm asking these Q's because we have a few Caravans of varying years and are trying to figure out what to do with them.

Actually we have a 1994 Dodge Caravan with the 3.0 L V6 Mitsubishi and the infamous A604 Ultradrive 4 speed tranny.
