Transmission coolers

[jacksum2]

Probably a very old subject to those who have been on the forum for awhile but I am new and don't know where to look yet. Has anyone had a transmission cooler installed by a dealer on a 2010 Tahoe/Yukon. What was the approximate cost? I have a lot of warranty left and would like to stick with a dealer if possible. Thanks , Jack

if you have the factory tow package, it already comes with a tranny cooler.
some do add an auxiliary tranny cooler. you can get one on Ebay for around $75.

if you don't have the factory tow package, you'll need more than just a tranny cooler.

Thanks bikendan, I have a factory tow package but not the heavy duty one. With the addition of a cooler, mine should be identical except for the rear end ratio which I probably won't change.

i'm a little confused. i have an '07 Avalanche, the same GM900 platform as the Tahoe/Yukon. in fact, it's the same as the Suburban, without the back seats.

my '07 Avy's factory tow package came with a tranny cooler, pre-wiring for a controller, 3.73 rear end, 7-pin connector and type III/IV hitch receiver.

did something change that they now offer two different factory tow packages?

Apparently so. My Tahoe said "Towing Package" and came with a factory 2 " hitch , 7 pin connector and pre-wire for brake controller which I have since added. According to a man who works for a chevy dealership and ran my vin number, My car does not have a trans cooler and has a 3.08 rear end. I think there is a heavy Duty towing package which has the exact same equipment as mine plus a trans cooler and a 3.42 rear end ratio.

Thank You DL but it apparently doesn't have 2010's in the database yet. I have not been able to find a site that has detailed vin info on a 2010 yet. I believe the info that I got from the other member is probably correct.

Thanks, Jack

I had a Suburban a couple of years ago, added a heavy duty transmission cooler installed by my local mechanic, around $150-200 installed. Hope this helps as the other responses did not address your original question. I didn't check with the local Chevy dealer, I don't trust them.

When we were buying our 2011 Acadia one dealer had quite a few without the tow package. While the slick saleman tried to tell us it would only cost a few hundred to add the tow package after; I asked him to talk to the service department. They said due to the Acadia's transmission putting one on after would be over $1000.

I hope yours is a lot less.

There are many different types and sizes of transmission coolers. Don't get ripped off from a dealer. It all depends on what you are pulling for weight etc. Take a look at B&M transmission coolers. If you go to their site you will see them rated by weight and BTU. I always used the largest I could get in my motorhomes and tow vehicles. While the factory one s are OK these are much better. You can even get a temp guage for them . Not a bunch of money, maybe $80 worst case. Install takes maybe 2 hours. If you are at all handy you can do it yourself. If you lived near me I'd do it for you
