    Question Transmission Cooler

    Does anybody know if all 2nd gen vans came with a tranny cooler? I was thinking about flushing out my a/c condenser and using it as an auxillary cooler, and it'd make it a lot easier if there is already a tranny cooler. In trucks a lot of the time they're inside the radiator, figured the vans wuld be the same way. If mine has a cooler already I figure i'll re-route the cooler lines into and out of the condenser and make a huge auxillary cooler for when I haul loads. I plan on starting a lawn care business this summer and I want the van's tranny to hold out. By then i'll have saved up enough money between that and my real job so I can buy a more reliable daily driver that uses less gas. I would like a van those, a 4th gen 3.8 AWD van though, the 2nd gen 3.3L FWD aint doing it for me.

    They all have coolers in the radiator. I'm guessing that an external auxillary cooler may have been optional like the later vans but I don't know for sure.

    You would probably enjoy the awd 4th gen with 215hp. a good 60 more hp than your van with some winter capabilities. But they come at a premium cost, even used. Getting a beater pickup may be a better option if you need something to beat around in for the winter that has awd.
    Candy the van. '98 Sport 3.8L 132,200 miles. Used trans at ~96k. Great piece of my life and a fine van.

    I don't know about all of the second gens, but they could be ordered with a towing package that included an auxilliary cooler that was in series with the cooler in the rad, and appears to be routed through the aux, then through the rad, and back to the trans., but any decent aftermarket cooler would be a help if you don't have one already.
    Look for a hose that makes a sharp bend toward the front of the van from the bottom left of the rad (left as viewed from the drivers seat) and connects to a small radiator looking item in front of the rad and air condensor that can be seen through the grille on the dodges, harder to see through the plymouth grille.

    I don't think mine has an external auxillary cooler, the condenser will be just as good as any aftermarket cooler anyways. I just need to find the cooler line going back to the tranny and re-route it back to the condenser than back to the tranny. I'll just need extra fluid line and i'll have to flush the condenser, other than that i'll be ok. It'll hold more fluid with the auxillary cooler and extra line too.

    I would encourage you to bypass the radiator cooler alltogether, since they tend to clog when the Torque converter fails and burn up the gears. If you get a sufficient size one with large diameter tubes that won't clog, it will be fine. You can also make one out of a 500 btu AC evaporator or condenser.

    It's running off the stock cooler now, the one inside the engine radiator and it's not clogged, cools just fine so I don't think extending the line and adding a second bigger cooler will hurt it.

    It is good that it is working now, but when your TC starts going, this cooler has fine holes that can be plugged with stuff as fine as coffee grounds, once it plugs your transmission will burn up in 70 miles or less. Happened to me with a brand new transmission that the cooler had not been cleaned out when they put the new one in. Of course, you can keep it, but If you install an aftermarket, it is superfluous and you will avoid one possible cause of tranny failure. That's my 2C from someone who has been dealt a few blows from these things.

    So it clogs because of how small the passeges inside are? I guess I could bypass it, I might not have to re-route the lines if I do, i'll take a look at it and see what I can do.

    Any transmission supply house will have a aerosol flushing cleaner for the cooler. The condensor is not likely to make a very good cooler. Just buy a large aftermarket one and mount it in front of the condensor.

    Can't argue with KOG because I don't know what kind exactly of condenser you have, but if it has the large tubes like my 05, it is likely good. I made one out of an evaporator from an 8k btu AC and it worked great. Had more tubes and surface area than any aftermarket type. I used one with about 3/8" tubes. You can buy a kit to install on the surface of your radiator at the parts store. But an aftermarket on that is adequate should be about $50 or so.
