Is there a gas fitting at home depot that will thread in there or similiar?
gmcman said:What I'm looking to do is attach a hose barb to the output of the cooler. You can pull back the rubber sleeve and unscrew the fitting.
lint said:I think if you take that nut off the cooler will come loose in the tank, I could be wrong, hopefully someone will chime in and confirm You are talking about the nut in the pic. with the black clip around it My tranny cooler hook up with pics - Chevy TrailBlazer, TrailBlazer SS and GMC Envoy Forum ''there is a quick release fitting on it now''
gmcman said:Basically remove the entire fitting and insert a male threaded hose barb into the cooler.
By pulling back the rubber sleeve you an get a flare wrench on it and from what I have gathered you can rotate the fitting with the line still connected.
I just don't know what thread style works.

gmcman said:Yes, I want to remove the nut from the radiator, I didn't think the cooler inside the radiator would fall if I remove the nut, can't imagine it would.
No drain, just one inlet and one out at the bottom of the radiator. It's easier to slip a hose over a barb than the cooler line.

gmcman said:Thanks......glad I didn't find a fitting, I didn't know it would break a seal.
The other end will be attached to the cooler, the one I remove will just hang there since it draws suction. I will be refilling through the dipstick tube.
This is for a fluid exchange.
gmcman said:I appreciate all the input.
I plan on doing this a little different by flushing the cooler as well. I see a larger nut on the cooler, that's not the one I plan to remove, is that the one that can loosen the cooler or is it the smaller nut?
RedEnvoyDenal said:To just do a fluid exchange take off the PASSENGER side since that the "from transmission to radiator/cooler", attach a hose and drain into a large bucket (about 12-15 quarts worth). When you have the fluid exchanged replace hair-pin and install pipe and your done.
One other suggestion if you decide to change fluid (always a good idea) use synthetic (my opinion)
drop the pan and change the filter at the same time. (if you drop the pan put a bung in, so next time it is easier to drain.

That fitting will give you a leg up on installing an external tranny cooler.
And going a little off topic, that tranny cooler in the radiator is far more substantial than I thought it was.

Dad-O-Matic said:I'm not saying it has to be GM, it just has to meet the minimum requirements for Dexron VI. If it meets the Dex VI standard, that means GM has tested it and given it their "seal of approval", i.e. it won't violate your warranty. Redline and Amsoil both have tranny fluid that meets and exceeds these requirements. I personally will use Amsoil for my next fluid change.
The older TB/Envoys used Dex III, but GM no longer supports that standard, tests or provides oversight on the manufacturer of Dex III. If you buy Dex III for an older model, you have no idea if it's will even meet that old standard. Any one can slap a Dex III label on their tranny fluid, but without GM's stamp of approval it really is just another label. If it's made by a reputable company (Pennzoil, Valvoline, etc) it'll probably work just fine in the older tranny's but for only a couple of extra bucks a quart, why take the chance?
lint said:OK . if your trying to put a hose barb on the driver side,, You can you this. Fitting, 2000-up, some GM applications Fitting kits Makco Transmission Parts. but you would neat to cut the pipe then put a peace of hose on.
