Okay,I am going to replace my radiator,and noticed my transmission cooler is just as bad of shape. Where would I find another being that this is not standard equipment on all jeeps. Also do the cooler really work? Because,I don't know how long mine hasn't worked but the fluid is burnt. Are they worth replacing or just go without?

 

in my opinion, it's in what you use your jeep for. I use one, and picked up one from the local parts store, but I got one of a grand cherokee at the JY and it works perfect. it helps extend the life your tranny, i think every 15-20 degree drop in fluid temp helps add years to the life, while at it you might as well pick up a tranny oil temp to keep track it

 

Yes, by all means replace it. AW4 is a stout transmission, but heat is it's weakness- and it generates a fair amount of it.
Most auto parts places have aftermarket trans coolers, most any of them will work fine. Or yank one at the scrapyard (flush it out well before use)

 

Grab one off an early 90's explorer at the junkyard. Bolts in really easily and greatly increases your cooling over the optional factory cooler. And costs under $15 normally.
