Trans cooler install on 07 GT

Why would I route the lines to the drivers side when the factory lines are on the passenger side?

Also, I wanted the lines going to the factory lines to be as short as possible. The longer you make them the less effecient the cooler is. I also wanted the cooler mounted to where it would get direct airflow. The only way to get that put me in a position that limited basically everything.

I was on limited time as well. In order to properly mount the cooler I was going to have to remove the radiator, fans, and hoses.
 


The trans lines hook to the radiator on the passenger side on my car. I can go take a picture in the morning if you would like.
 
Better yet, here is a photo from a website selling one

In order for an efficient install I wanted a few key things.

1. Airflow over the cooler. The only way to get sufficient airflow is to mount the cooler all the way at the top of the condenser. Due to the size of the cooler some of it was even blocked by the center bar running in front of the condenser, but I could have dealt with that.

2. Clean install with lines as short as possible. Running all that extra line is not efficient at all. Not only that, but you don't want the transmission pump to have to work against gravity to get fluid back to the trans.

So basically with where the cooler had to be mounted, and how the lines needed to be ran, it wasn't going to work without cutting and/or drilling. Also, I wasn't in the mood, nor did I have the time to go removing the radiator and all that other crap today.

1. You dont remove the radiator at all.
2.The lines of every 4T65-E come out on the transmission on the driver side.
3. The cooler is easily mounted in the horizontal position
4.Working driverside to front bumper is the shortest routing period.
5. The cooler will get more air being in its own unit and mounted low in the bumper as described .
 
1. The install kit that came with the cooler required access to the back of the condenser. Access to the back of the condenser requires removal of the radiator.

2. Yes the lines may come out of the drivers side of the trans, but the lines come out the passenger side of the radiator. My plan was to cut the metal line, flare it, and install the hose.

3. I don't know what cooler you have, but the 1404 is rather large for the area it has to be mounted.

4. See number 2.

5. The cooler will get almost no air at the bottom. In order to get the most air it needs to be up top, behind a grill.
 
Save yourself the trouble and get a Dex III/VI equivalent. I work at a Valvoline and we preform fluid exchanges (not flushes) on people's trannys all the time, but I will not service GM vehicles with our universal fluid. I've only heard of one person's car having trouble after using it, but I play it safe and just don't.

I honestly did two pan drops with Walmart's Super tech Dex VI fluid with a shift kit and filter a few months ago, and my tranny has been solid ever since.

1. You don't need to access the back of the condenser, the plastic pins go through the rad too.
2. "Yes the lines may come out of the drivers side of the trans" Stop there, you cut and flare them THERE. "My plan was to cut the metal line, flare it, and install the hose." that's right, right by the trans. More efficient, the lines are shorter like you wanted. No need to run them to the stock rad when you don't use the stock rad. (or shouldn't use)
3. the 1404 has to be mounted long ways horizontally. There's a good pic on the "what did you do to your car today" forum recently.
4. See number 2.
5. The cooler will get the most amount of air at the very bottom. The car is designed to trap air at the bottom, and send it up to the coolers. That's why it's called an air dam. All of the car's cooling air couldn't come from those two tiny grills, could it?
