Question:
Good Morning 2022 Lexus GX460 Derale 9000 series trans cooler. Towing a 5000 lb boat Vehicle is 6000 lb so GVW is 11000lbs Is the Derale 13612 enough cooler or do I need to step up to the 13613 ? Space is critical behind the grille Thank You

Expert Reply:
Hey Jeff! The best option is typically the largest one you can fit in your engine compartment. What did you mean when you said space is critical behind the grille? If you have room for the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets - Class IV # D13613 then I would get that over the Class II # D13613. If you don't have the space for it then the decision is made for you with the # D13612 as the best option. The Class IV # D13613 is only a couple inches taller so it will probably fit but it is best to double check.

Hey Jeff, how did things turn out with the Derale transmission cooler for your GX460? Were you able to make the larger Class IV model fit behind the grille? Your results could really help others working with tight space limits.
