I need to get my timing belt/water pump replaced as I just bought the truck at 100K and it had yet to be done. I also want to add a transmission cooler as I will be towing occasionally fairly long distances ( Jacksonville to the Keys, 23 foot bay boat, faily light weight, 5500 lbs. total). How expensive is it to add the cooler and is there enough room for the cooler in the already cramped engine bay of the V8 4runner ? Is there a Toyota accessory transmission cooler or is this something I will need to order aftermarket and have the dealer install ? Has anyone found one with a separate transmission temperature gauge ? I found this very helpful with my old Yukon Denali. On a separate note, I was quoted $893 for changing timing belt, water pump and seals, does this sound reasonable from a dealer ? Thank you in advance.

I also interested in an auxillary cooler for towing. Oh and I'm sure any old aftermarket gauge can be fitted to your 4Tunner, however if the computer can monitor transmission temp then a blue tooth OBD2 scanner like the Rev app for iPhone can get you done. I used it in the past on my Audi to monitor fuel pressure and a/f ratios and such.

does it use the radiator or is it an external cooler?

Radiator, there's a second smaller radiator just in front or behind your main radiator which is the tranny cooler.
You'll be fine with the drive. I made a trip from Tallahassee to Fort Lauderdale with a fully loaded 6'x12' Uhaul trailer going 75mph and not once had heat or brake issues. You'll be fine, considering you aren't slamming on the gas/brakes constantly.
