Do they make external trans coolers for these? Will be pulling a cherokee on a car trailer a couple hours each way.
Thank you

I'm not sure I need it no... but the trans runs at 175 unloaded so I figure pulling a jeep on a trailer will get it up there.Just to be clear, the truck has a factory transmission cooler. If you put another one on it would be for auxilliary cooling. Are you sure it really needs extra cooling?
I don't know why you couldn't put on a universal cooler. Haven't researched this vehicle specifically, but many years ago all of the aftermarket coolers were universal fit.
Well, not necessarily. Not exactly how those systems work. Not much different than saying that your engine runs at 205 while driving empty so it will get a lot hotter towing a load....I'm not sure I need it no... but the trans runs at 175 unloaded so I figure pulling a jeep on a trailer will get it up there.
it has new RL fluid in it. just put it in 2 weeks ago.Your better of getting a custom tune with that POS 6 speed and throw in either R.L or Amsoil trans fluid.
well i know that. but i just feel like it will get hot. its the express package with the high gears. not ideal for towingWell, not necessarily. Not exactly how those systems work.

I believe there maybe a thermostat block that keeps the trans fluid warmer on these trucks. The make a bypass for the thermostat block that will keep the transmission cooler.I'm not sure I need it no... but the trans runs at 175 unloaded so I figure pulling a jeep on a trailer will get it up there.
Burla knows more about the RFE thermostat bypass then i do,i know they do make one for the RFE though.I believe there maybe a thermostat block that keeps the trans fluid warmer on these trucks. The make a bypass for the thermostat block that will keep the transmission cooler.
@Wild one knows which years have the thermostat block on the 66RFE
so who would i talk to about getting a bypass?Burla knows more about the RFE thermostat bypass then i do,i know they do make one for the RFE though.
Let's see if @Burla chimes in.so who would i talk to about getting a bypass?
Contrary to popular belief, I'm not sure where it is located on the 5.7, both the 5.7 and 6.4 have them, and yes if you do get it off asap. I'll punt to @Hemi395 , he knows for sure. Even if you are in cold plac e where you can argue in favor of them, eventually the clog and there goes the transmission. I do believe in this case they are all the same, diesel, 6.4 or 5.7. Look up rfe thermal bypass block threads, tons of info there as far as which ones are great, this is what one looks like they are plug and play.Do they make external trans coolers for these?

Awsome! Where do you get this bypass? Where do I buyhere is jeffs video... so if you see that valve or find that valve, it is this simple. Not sure but I think corey will tell you this is in a different location, up in the engine bay around your cooler. I would have done this but in 2010 we didnt get this garbage. This was the 6.4 location.

Look through the pass side of your grill,in the upper corner if you see an aluminium block roughly a couple inches square,with 4 good sized hard lines running to it,you have the thermostat block.That's where it was on my old 13 with the RFE transmission.I bypassed it with transmission cooler line,but that was long before you could buy plug-n-play bypasses,now they are the way to go,instead of doing it the old school way i did itso who would i talk to about getting a bypass?
Gotcha. Mine is a 17 6 speed. Canada truckThere is a link in that post amazon, first locate it so you know you have one.
WE dont know your truck, if it is a 2500 my guess is 99% you have one, the 1500's seam to be a mystery as most of post 2014 came with 8 speed, we do know those classics are out there but not a lot known about them.
