Towing long distance / Tranny cooler

[FunRunr]

Hello all, my previous screen name was locked out for some reason while i was in Texas for 7 months. Anyway, the Air Force is moving me from South Carolina to Denver, CO at the end of Sept. I will be towing a double axle uhaul trailer behind my '10 SR5 4x4 V6 with some tools and furniture in it. The 4Runner is rated for 5k lbs towing. Do the '10 4runners come with a tranny cooler installed? Will towing that long of a distance have a negative impact on the 4runner? Thanks.

Don't believe there is a specific Tranny cooler - just the lines that run from the tranny to the radiator to cool the tranny.

I just pulled a trailer 750 miles in one day yesterday to pickup some furniture (DE to NC and back) - it was a 6x12 with a sectional sofa. granted it was not the heaviest load (that will be tested today when I go get a couple tons of pellets to stock in the garage). It performed well on the drive, just don't expect the best gas mileage.

I don't think you'll have anything to worry about as long as you keep the tires aired up correct, especially if you are going to be pushing max weight capacity.

Awesome, how did the trailer handle behind the runner? any swaying? what about stopping? Did you have any problems? How fast did you go? Thanks

I can't imagine "some tools and furniture" are going to cause you any problem.

Be sure you load the trailer such that you have adequate tongue weight - 10% of the trailer's weight is a good estimate. This is important for happy trailering. And, as stated air up your tires. Me, I'd go to the max that is stated on the tire sidewall.

You may want to move the tranny over to "4" for inclines, especially if you find it hunting back and forth.

Don't know how you'll load the 4R, but the more weight toward the centerline the better. And be aware that your stopping distances will increase dramatically.

.......And be careful out there.

I did not experience any swaying at all - although it could be because of the type of trailer I have (older heavy duty, single axle, not a long tongue distance from hitch to trailer). Stopping was not a problem, but there was not a lot of weight on the trailer, the heavier the load the more distance you need to leave to stop safely (unless you have trailer breaks, which help, but are still no help to allow driving like a sportscar)- fastest I went while pulling was around 80.

The fish tailing experience can be minimized with propper weight distribution - if one side is heavier than the other you will get more swaying. for example, heavier items should be placed centered over the axle, etc.

Slow and easy, just remember its not a race to the final destination (and disregard the speed I mentioned, if I were pulling a heavier load it would be 65-70ish). And always check, and periodically recheck, tire pressure.

Considering you will be towing a 2,000 lb trailer, plus whatever you put in it - cross country and through the mountains, I'd definitely recommend installing a transmission cooler. It's cheap insurance.

All 5ths already come with a transmission cooler.The kind that's built into the radiator.
In the factory repair manual see -Drivetrain-Automatic Transmission/Transaxle-Oil Cooler

Thats what i was wondering about the most. I'm figuring a queen size bed, a tool box, chop saw, air compressor, two bikes, a large chair, and some miscellaneous items cant be more then 4k. Does anyone have any experience pulling a uhaul 6x12 with trailer brakes? Thats what im using and im pretty sure they come with trailer brakes.

I dont have access to the repair manual, but when it is integrated into the radiator, like most regular vehicles, any serious towing should be supplemented by an aux cooler.

The uhaul will have surge brakes (these are passive and automatic). It will probably have a 4 pin electrical connection for brake lights and turn signals.

You should be fine.

Drove one of those around for 2 days last month with about 600kg in the back. Didn't have any problems except the ball on my hitch came loose. Looks like I should have used thread lock or something.
