I have been doing some research on aux. tranny coolers and am trying to decide if I need one.
Maybe some of you saw my thread about the odd shifting into drive issues with my 05 rubi LJ auto, after changing over to amsoil. I will be switching back to atf+4 asap and hopefully that will be the best idea, unless someone recommends something else? It has 50k miles, fluid was clean before the amsoil too.
I know that it is a good idea to add a cooler for towing, and long heavy pulls on hilly roads, but still wondering if I need one. It is my DD, and now mostly around town and highway here and there. Then of course wheeling trips (driven to and from trails 1.5 hours away, and then a few trips per year out of state, 10-15 hours away) where I use it what it is made for. I know rock crawling puts more stress on the tranny and probably heats the fluid up quite a bit more, especially in 95+ degree florida heat. But will a cooler help this? It wouldn't have much air flowing through it at crawl speeds, but does the clutch fan solve that? Or would it need an aux fan attached to the cooler too? I was reading the thread about trans running too cool and that it is sometimes pointless to have a cooler (especially if a thermal bypass valve is used).
I am just lost on the whole cooler issue and if I should get one, which one is ideal and fits properly? Thanks for any advice! I want to get this settled before my next harlan KY trip in april. Thanks!!!
