hey...can you give a brief rundown of how to install a tranny cooler? I have the basic Idea, I just need details please
o One of the most important things is to use the proper line (return line in this case). For a 4L60E it's the line going into the top of the radiator cooler. The last pic that kirkrhughes posted shows this real well.
o Use brackets to mount it, don't use the thru-core style.
o Make sure you have the fittings/hose/clamps you'll need. My B&M kit had everything I needed. Assuming barb type fittings on the cooler, you'll definately need (assumimg 3/8" ID hose):
- 3/8" x 3/x8" NPT male tapered fitting for the radiator
- 3/8" x 3/8" NPT female fitting for the OE supply line
o Verify that the cooler has a bulit in low pressure drop bypass. If not you may want something like a thermostatic control valve.

Basically:
1) Figure out where to mount it.
2) Mount it.
3) Disconnect the supply line.
4) Roughly measure your hose lengths and determine routing.
5) Install male fitting on radiator cooler outlet, connect hose to fitting, connect other end to cooler. Don't forget the clamps and thread sealer.
6) Install female fitting on supply line, run second hose from cooler to supply line.
7) Start it up, check for leaks, top off AT fluid per OE procedure.

You can use a mounting location like kirkrhughes did or something like I did here:





Hope that helps some. Good luck
