Transmission cooler for Grand Caravan 2003 with 3.3

It is very, very difficult to keep your transmission fluid too cool. Transmission fluid coolers are much less expensive than transmission repairs or overhauls. The transmission may (or may not, depending on whom you ask) have been "greatly improved" for '01, but it is still asked to haul around an enormous vehicle relative to its torque capacity. Buy and install a fluid cooler and consider it a cheap insurance policy.

My 01 tranny lasted all of 8 months. So far the 03 tranny is a year and (I think) ok. The tow package should be std. equipment.

Are you sure it wasn't just a sensor failure? Admittedly they should not fail but it still a lot less significant than a real AT failure.

The gears turned to mush - saw them.

Tom that's a classic sign of of that Hawaiian disease=lackalube. Coolers are cheap insurance. However, by now yer factory cooler might be restricted from the nuke down-so hooking a cooler up in series with it may not be prudent. Respectfully submitted,

Right. Not on a new vehicle unless the pump failed. Which it probably did. Chryco trannies are a POS (A604)

Van was destroyed in freak boating accident so it is no more.

I can't speak for the '03, but my '96 has a cooler integrated into the radiator. When you add a cooler, you can either "replace" the existing one, or "add" it inline with the other. The size of cooler you buy depends on which way you go. If you go to the parts store and read the packaging, hopefully there's a discussion of it's application to certain vehicles for both cases. You can buy these things starting at around $30 going up to $100 or so depending on the size and brand you get. Installing them is only hard to the extent that getting access to the front of your radiator is hard. I can't speak for the '03 though.

These transmissions aren't heavy duty and were originally designed for use on cars. It's a crap shoot even when you don't tow. If you do tow, I'd go easy while driving, get the extra cooler, check fluid level and condition regularly and be very diligent about changing the fluid/filter.

I found the brand called TRU-COOL and from wha tI read it is a LPD type that it is as per OEM, but but I am not sure if this can void my warranty. I rather put this product instead the Dodge one, from what I read it provides more flow , it is self regulating meaning the oil flows on top when it is cool and as it warms up it goes through the whole cooler. I can just see my dealer saying no good your unit, here in Canada the dealer part is 131 and the TRU-COOL is 75 . What I am not sure is who makes the Dodge part. The TRU-COOL is advertised as a OEM replacment. We might have no choice and go through the dealer

To add what David said above-consult yer owner's manual for recommended tow capacities and further see if towing in overdrive is permitted. I doubt it is and may not even be addressed in the manual. Lastly, it would be prudent to install a trans oil temp guage to further protect yer investment. Respectfully submitted,
