Tranny cooler install question

So im looking at a 4runner that is around 600 miles from my home. It is a 99 sport with 200xxx miles and has never had the external cooler added or radiator replaced.

What im wondering is if this is something I could do in the parking lot if I had to tools and parts before I take the drive home. The truck is in AMAZING shape and this is the only thing Im worried about.

I have worked on cars nearly my whole life and am capable of doing anything from fluid changes to engine swaps ect. Im just wondering if anything special is needed that I wouldnt be able to fit in a tool kit on the plane.

Can I simply unplug the lines from the radiator, splice in a coupler into the soft rubber to the new lines and run to the cooler (I would run all new lines later on) or do I need to go all the way back to the transmission with new lines?

If I can splice into the old lines right out of the radiator, it seems like this would take no more than 30-45 minutes to pull the grill and skidplate, undo the old lines, plug the holes on the radiator, connect the old lines to the new ones with a coupler and zip tie (again temporarily) the cooler up.

Am I correct on this?

Also are their any auto parts stores that carry the coolers? I will be near seattle so Im sure somewhere would have one but just wondering input. I just dont want to have to buy and pack the cooler on a plane also and just incase I dont buy the 4runner.

Any input is appricated

Thanks guys

Edit: also if anyone knows the sizes of the couplers (either double sided barbed nipples with hose clamps or barbed nipple on one side with a fitting and the mate for the other side), I would appricate it.

You'll need any oil pan, don't want to spill any tranns fluid. The metal lines coming off the trans stop just behind the radiator, then rubber ones attach and run to the radiator. This can definitely be done in a parking lot.
 
Yup, the most time consuming part is taking the grille apart and then deciding how to route everything. If you splice and don't route all new lines, it won't take hardly any time at all.
 
great, thats what i needed to know.. I can buy a cheap oilpan and fluid at any auto parts store so...

now anyone know of nationwide chains who carry them so i can buy one while im there? also the size of the couplers/fittings

thanks guys
