I finished up the transmission cooler install yesterday and wanted to give you guys a little summary of the install. For one, it was very easy. On a scale of 1-10, I would give this job a 2. The posts I used for the install are linked below:

Project SportRunner - Transmission Cooler

Items I purchased for the install:

1) B&M 70268 cooler
2) 4 feet of 3/8" trans hose (not enough if you are not using the supplied lines)
3) 4 feet of 3/4" heater hose (too much - only need a foot)
4) 1 quart Castrol long life ATF fluid (didn't use)
5) Zip ties
6) Hose clamps

Some thoughts on the install and how I went about it:

1) I left the truck sit for about 3 hours before starting so I wouldn't burn myself on any of the hard lines
2) I mounted the cooler exactly like BigFishAllDay did - on the radiator with the supplied mounted zip ties with the barbs facing the passenger side.
3) Ran the new cooler lines through the hole where the A/C lines run. SUGGESTION: wrap the edges of the hole before you run the lines, that way you have more room to work with.
4) When removing the stock rubber lines from the transmission hard lines, I just sliced the instead of trying to pull them off. Way easier and you won't end up with battle wounds like BFAD did.
5) I bought 4 feet of 3/8" trans lines thinking it was enough but how we ran the lines, it wasn't long enough. What I did was I used both the line that that I bought from AutoZone and the supplied line from the kit. SUGGESTION: If you don't want to use the line supplied in the kit, I suggest buying 8 feet of 3/8" trans hose. Only use trans hose btw, don't let someone talking you into using P/S or heater hoses. The lines supplied with the kit and 4 feet of 3/8" trans hose is plenty of line but one or the other isn't enough.
6) I lost maybe a half cup of fluid when I did the swap.
7) I twisted off 2 of the three bolt heads that hold the pan that's under the engine. Make sure you have a drill/tap incase this happens. It was only a 5 minutes hang up but if we didn't have a drill and bits, we wouldn't have been able to remove the pan.

That's all I can think of. The install was easy and I recommend everyone do this mod!

Thanks and happy install :frog:

I did mine the same way, only I put the In/out trans lines in a much larger hose to shield them from any possible abrasions when they ran up by the frame and through the radiator support. I havent had a problem in over a year

I can take some pictures later tonight
 
I will probably buy some thicker ID hose so I can protect them some more but for now I think they are good. Going to drive the rig for a few day then check it all
