There was talk about a transmission cooler

[Geo-TH,In]

I was flipping through the information screen on my car and noticed the water temp was 195F and the transmission was 145F.
I thought how can the transmission be 50 degrees cooler than the water temp?
I recently bought the one year old XT5 car a few months ago.
When I parked the car I opened the hood. There are two lines going to the radiator and one line appears go a transmission cooler
in front of the AC coil. Who would have thunk you can get a luxury Caddy with a tow package. No way would I ever think of towing anything with a car.
Do you have a car with a transmission cooler?

In the old days we towed everything with our cars. Those were bigger cars though. Have you seen the Lucille Ball movie The Long Long Trailer? If not you should, very funny movie.

A couple years ago I saw my neighbor go by pulling his 12 row corn head with his Escalade. I just thought, Well OK, if he wants to, it's his Caddy.

@Geo-TH,In
Does it have a hitch? You might not see it. Some have a small panel that you take out of the plastic cover below the bumper.

Or, what you think is a tranny cooler is a tranny warmer upper.
To make the tranny operate at the optimum temperature sooner and more efficiently.

Yes it was.

Maybe GM doesn't think the transmission in that vehicle will stand up without the extra cooling capacity...it's not like the newer model vehicles never have transmission problems. It seem to be we hear about that more and more in recent years, albeit more so about pickups.

It's just a government motors outfit. So probably some gadget just to make it cost more to work on. And more work to work around it. Built so cheaply that without it the transmission will not last for long like most auto trans are.

While traveling through Canada a few years ago I was surprised at how many small, sub-compact, front wheel drive cars had frame hitches mounted on the back.

One use for a receiver hitch on a compact car that wouldn't be able to pull much of a trailer is to allow bike racks to be mounted.

Not only funny, but VERY ACCURATE. Even though it was made in the fifties, pretty much everything in the movie is true about camping today.

I watched a Video about servicing the AC on a BMW it did not have a AC condenser out front of the radiator. The system uses glycol to cool a small condenser just above the compressor. It looked like a small package unit. They are going to get these systems so small with no interior evaporator in the passengers compartment they will be able to use cooled glycol to cool the passengers. The refrigerant will be propane its going to be a small amount so small it would flash off before anything could burn. Its coming soon.

Agreed. Most of these little econoboxes can haul up to 1000 lbs. which would be a jon boat or maybe a utility trailer for a lawn mower.

Pretty much every vehicle with an automatic transmission built in AT LEAST the last 25 years has an auxiliary transmission cooler. If you don't think yours has one, go look. You'll be surprised.

 

[TerryfromSWIowa]

Is it really a towing package or so much stuff blocking air flow to the trans that the rad is not enough to cool it.

We left North Dakota in ‘66 in a VW bug pulling a home built trailer. Dad used it for years. He was a very gentle driver.

Transmission cooler - I may be wrong - it was a long time ago, but I think that the '56 Mercury that I owned had an air scoop off to the side of the automatic transmission.

@Geo-TH,In

Since you have a GM product, you can go to the website below and enter your VIN.

It will then give you a savable/printable rundown of everything it was built with. Pretty much a decoder for all those codes on the big glovebox door sticker then some.

Maybe I'm reading this wrong, but to the best of my knowledge every automatic transmission I've ever seen has had some sort of cooler, most were internal in the radiator, perhaps an external cooler was now a less expensive to manufacture, I don't know.

 

[TheBartman47]

My brother has a 2016 Cadillac CTS putting out over 700 hp and has a transmission cooler... not because he's going to be towing with it but because it's a high performance car.

My 1975 Monte Carlo came factory stock with the transmission lines going through the radiator, but several years ago I swapped that over to a separate external trans cooler. I too am not pulling trailers with it (though I could) but is because it's got a 406 engine at 532 HP and a "bullet proof" TH350 transmission that needs more cooling than what stock radiator cooling would provide.

Must be a CTS-V with LS V8 and rear wheel drive.

SWEET (I have been shopping for one)
