Tranny cooler installation

[Egan]

Step 1: remove the old cooler. I unbolted it and the cut the lines with a tubing cutter. The line that runs to the driver?s side was cut far out on that end to reduce the amount of hose I would need for the new cooler:



To make my life easier, I removed the airbox tube between the throttle body and filter. I also removed the passenger side fender liner.

Step 2: Break apart the line that runs inside the radiator. I had to use my sawzall because I couldn’t get the tubing cutter to spin due to space restrictions. The circles are for the black tube at the top and the silver tube at the bottom.



Here’s where I cut the lower one. Just turn it up to keep the fluid from running out:



The other end of the cut will run to the cooler. The black tranny line you see runs straight to the driver’s side of the stock cooler and was cut in Step 1:



No pictures of the cut at the top, but it should be straight forward. I connected the two radiator cuts together with some of the hose that came with the new cooler. This step is not really necessary, but others had done it and it provides a clean installation.

Step 3: Prep the new cooler by installing the NPTxbarb fittings:



Next, route the tubing to the new cooler location. The tube on the passenger side came from the lower cut shown in Step 2 and the tube on the driver?s side is connected to the end of the tubing that was cut in Step 1:

Step 4: Pop the cooler in place and secure it to the body. I had it pushed all the way over until it hit the mount for the power steering cooler. I used a sheet metal screw on the driver?s side because the cooler bracket fit flush, but I had to use one of the included straps on the passenger side:

Step 5: Close the hood and realize it won?t close! The cooler had to slide over towards the driver?s side by ? an inch or so. So I had to ?trim? the ps cooler bracket (thank you Mr. Dremel) to make it work. Fortunately, I didn?t have to redrill the hole on the driver?s side ? the bracket has 3 holes so I just used the one on the left instead of the one in the middle. For the passenger side, I added another hole and tweaked the bracket (it is what was hitting the hood):





Lastly, run the engine (after putting the airbox back together) and check for leaks.

Nice wright up...

Dude I warned in one of the recent threads the very issue you had. The hood not closing due to tight fit. Luckily I caught mine before things were bolted down. Sorry you didn't see it

For the power steering I just relocated the bottom mount (swung bottom towards driver side) and used a nut and bolt that came with the Trans cooler to secure it.

I saw your post, but everything looked like it lined up perfectly. It wasn't off much so it was no big deal to fix. You can see where the hood was hitting if you look to the lower right of the last picture. Just above the bolt you'll see two small parallel scratches. It was really modifying the bracket that fixed it more than sliding the whole cooler towards the driver's side.

so here is the thing...

the viscosity of the fluid is going to warm up to whatever it is going to warm up at splashing around in the tranny and cycling through it.

Is that 60 degrees? 70, 80 or 90 degrees? not sure.

your cooler is going to cool at most to the ambient air temp outside.
there is no way it can go lower than that unless you have something else that is actively cooling.. I.E refrigerant type..

so the magical numbers are..
what is the oprating range the tranny needs ?
and ambient temps outside.


at most, the pump is the only thing that should really be affected by cooler fluid as it has to work a little bit harder.. but honestly, it will have minimum inpact
