Yes, and if you are going stand alone I would think you would need two of the fittings as not to cut the original lines. Everything I read with the exception of what you quoted never mentions any positive or negatives to which lines go where, don't really see how it could help or hurt which ever way the lines were installed or the direction of the cooler in and out lines . Be careful with that magnetic filter also, some reviews said the nipples break easy. Its plastic, I am keeping a close eye on mine. I also have 2 magnets in mines as well, one installed right around my drain plug and the other I attached to the filter. It is hard to find clearance inside the pan for the second magnet. I also have the 2 strong ones still attached to the outside of the pan.
I had just placed my order before you replied; seconds really. I included the extra hose just in case.
Also, I plan on running it inline and not standalone.

One more thing to mention, when I did this it was still very cool. The weather this last week has been in the high 80's , I have seen a high of 182 degrees on the gauge and it cools down to about 174 or so after i get on the highway and home. Its a good improvement, and I wasn't expecting miracles but I thought it may be lower based on some others findings from the board. I really think stand alone is the way to go in warm weather climates, our winters seem to last longer lately so that wasn't an option and I'm good with that.

One thing about the extra hose I received it was bigger outside diameter for some odd reason, inside diameter was the same. The fuel injection clamps I bought wouldn't fit over it. The kit comes with clamps but I have had good luck with those in the past so I used them in the area that was harder to get at. Set it all up on the bench after you figure how you will be installing to save some grief working in a small area. I mounted mine the way I did as I had to finish up quickly after losing so much time dicking with trying to remove the plastic splash shield. Its mounted solid but not how I planned. I really think you would benefit more from a stand alone installation being in Florida, I'm sure the temps I'm seeing now will increase even more once it gets really hot and humid. It's ridiculous we even have to deal with this nonsense to fix GM's screw up.

Well the OEM design is that way (bottom in, top out) and Tommy231 makes a decent point:
Having it top to bottom also makes fluid flow more efficient through the cooler so the trans pump works less and has less pressure drop.
living in a place where it hits 120 degrees in the desert and not seeing over 187 degrees yet on my temp gauge means there's some merit to not following oem design

Correct. And that bottom line does not look fun to get at either although I really didn't look at it all that much as that was not my plan. I only mentioned this as I would hate to see you go thru all this work twice if the results will not be what you hope for. Everyone's transmissions may be the same, but how they are holding up inside could be different due to abuse or service intervals. Some could have converters that are more worn causing more heat, some could have more clutch wear. I'm just saying what works on mine may not show the same results and visa versa for yours in comparison . I like my car, hate this transmission. Almost wish I didn't have a gauge because now I'm obsessed with monitoring it .

You can not use 2 of the fittings I suggested, I was confusing myself overhinking that install.

Good to know. Thank you. As 91parkave has also stated the fittings for the stand alone installation will be different then the ones I used. I think these should be the ones for the stand alone, someone who has done it that way hopefully will confirm. Amazon.com: Hayden Automotive 392 Transmission Line Fitting Kit: Automotive

Don't you mean these fittings since the stock ones are threaded?

Cooler is well worth it.
The shop ran the lines from the trans to the cooler to the radiator and back to the trans (I personally think cooler only or trans to radiator to cooler ould make more sense).
The cooler has a fan that comes on at 180 F (After the car heat soaks it's on full time in the city).
I also did the dorman pan and a shift kit.
Huge difference in the trans and it doesn't feel "fatigued" after hours of driving and lots of stop and go.
Not to hi-jack, just encouraging everyone!
