Transmission Cooler Recommendation for 2007 Lexus GX 470

Question

Question:

I have a 2007 Lexus GX470. I will be towing a 3,300 lbs. camper trailer. Im worried that my factory transmission cooler will not be enough. I live in the south and will be pulling the camper throughout the summer. I just installed a ScanGauge to monitor temps, but have not seen what they are yet. I still would like to play it safe and get an additional cooler. Which additional cooler would you recommend? Theres not much listed for the GX, but the 4Runner V8 of the same era is a very similar vehicle. Thanks,

For a transmission cooler for your 2007 Lexus GX 470 the Derale transmission cooler part # D13503 would be a really great option that will keep your transmission fluid temperatures low so that you get the maximum life out of the transmission.

The reason that you cannot find a list of all load ranges and the weight capacity for each in regards to trailer tires is because it will be different for each size. For example, a 205/75-15 tire like part #AM10245 which has a load range D rating is…

The transmission fluid temperature you have of 210 degrees while towing up an incline is a little high but once you hit flat ground, the 185-195 degree range that you have is perfect. Therefore, I do recommend you install a supplemental transmission…

Yes, since there are 2 RCA connectors on the Custom Third Brake Light Camera System w/ Rear View Mirror #GCH74FR you can connect a second camera to this monitor provided it uses that RCA connector for the video feed.

Engine oil gets much hotter than power steering fluid so a power steering cooler such as #D13310 would not do much of anything to cool the oil on a motorcycle. Additional parts would also be needed so I do not recommend it. For an oil cooler…

The various coolers aren't vehicle specific. The most efficient spot to mount a cooler is directly behind the vehicle grille, in front of the radiator and the A/C condenser. Unless you continually run your vehicle in a very cold environment,…

Answer 9

The 2010 and 2006 Chevy Silverado are from different generations and would use different tailgates, so you wouldn't be able to swap the two. This being said, we do offer a camera system that would look pretty similar to the OEM systems. I'd…
