Transmission Cooler - Yes or No?

[bcomo]

I was wondering how many of you have an external Transmission Cooler.

If you do have one, did you do it "just in case", or because your transmission overheated?

If you don't have one, has your transmission ever overheated?

[FeFranco]

I do not have a transmission cooler and since I don't have a trans temp gauge, I do not know how hot it gets. If you have one you should install it. You may be adding another quart of oil to your capacity which never hurts and can be beneficial.

How can you tell if the trammy is overheating

[bcomo]

That's a good question.

From a post that Husky35 did -- there's an overflow tube at the top of the tranny that goes down the right side. When the fluid gets really hot, it overflows out the tube, usually onto the exhaust pipe and smokes.

Unless you have a tranny temp gauge (and I wouldn't know how it would hook up) I don't think you would know.

So, anyone else have one -- and why? Or, why not?

Thanks

I don't have one YET, but they are affordable, and cheep insurance IMO. I think B&M makes a small one which comes with a small electric fan too. One could do away with the OE internal radiator trans cooler, and run this one alone I would imagine. Just plug those fittings closed on the radiator, and reroute the OE trans lines to the B&M external cooler. It would help keep the coolant in the radiator somewhat cooler....

So, in your case, you would put it on for insurance, not because you've had a bad experience with tranny overheat. And you're in the hot country, like me.

I was thinking that with A/C, there's already a large condensor (almost as big as the radiator) in front of the radiator that resitricts air flow. Adding another, even small cooler, in front of those two would restrict the air flow to the radiator even more. And, getting to that cooler if there's a problem is a real bear.

The B&M unit with a fan would help with that issue though.

A trans cooler is probably a good idea. You want to run it in conjunction with the internal (radiator) cooler. If you don't, when sitting still in traffic (Aw c'mon that never happens) with no air passing thru the extn'l cooler is pretty much useless and the fluid will get too hot.
You run the inlet line to the radiator, then out to the extn'l cooler,then back to the trans.
Hayden makes a small one (aprox 12" x 3"). It can be mounted right to the side of the rad/supt (out of sight) On our generator equipped Bird's an aux cooling fan (even a small one) is almost out of the question (too much power draw)

John -- Do have one on your car now?

Have you ever had any tranny overheat (fluid blow-by) problems?

Thanks

Summit auto

Summit Auto sells one that mounts under your car next to the frame. that would mount right nice next to the tyranny where the sub frame is attached to the front frame.

They are aluminum so they are good heat conductors.

about 3" square with fins and different lengths for your
ride.

This is the way I was going to go if mine runs to hot, but I have not yet had a heat issue.

as for the temp gage it would go in the fluid out line from the tyranny to give you the proper temp reading the gage usually comes with the tee to install the sender in the line.

The frame mount sounds good. That would be easier to get to.

Thanks
