Trans cooler routing C6
Fitting a new more compact trans cooler in my 82 F100 4X4 with C6 auto like this
New cooler has a fan mounted to it & I intend to run it through a thermostatic switch. This time round with the new cooler I was intending to utilise the radiators cooler as well.
In my head I had decided I was going to go to the cooler first & radiator last reasoning being that during warm up the radiator might help warm the trans oil slightly without losing that heat into the cooler & the reverse if the oil exiting the cooler is still hotter that the radiator. In my head I thought this would keep the pan temp the most stable.
Then I received the cooler & read the instructions & they very clearly state to go radiator first cooler last.
is this all a bit six of one & half a dozen the other or is there a reason for their proposed correct way.
Thanks in advance

Thats the way mine is set up on my F250, it goes through my cooler in the radiator, and then into a larger cooler that I installed and then into the factory secondary cooler so I have a total of 3 coolers on my truck

This is where I ended up mounting mine. No need to go back thru the radiator, I don't believe in heating up the cooling water just before it goes back into the engine. Besides, the cooling lines have to go way across the other side of the car to get to the cooler in the radiator. I've got a temp sender in the pan so I can keep an eye on the temp. The fan's hooked up to the oil cooler thermostat, I've got a telltale light in the cab and it's never even turned on.

Nice job.
You make a very good point about heating the coolant just prior to re entering the engine, I was concerned about the trans staying to cool for longer with the extra coolers. I guess thats hardly going to be an issue in a faeries.
How long does it take your trans to get to 80/90deg C of a morning ? ......verse engine warm up

I've got one of these Remote Oil Thermostats which is supposed to recirc the fluid until it gets up to temp. Even with this it still takes its time to get to 180 (all my gauges are US) so I'm wondering if I hooked it up right or if its faulty. Doesn't overheat so I'm not overly worried at the moment.
I'd suggest that plumbing it thru the radiator would only be beneficial in winter when you might want to heat the trans fluid up a bit quicker. Depends on how vicious winter is where you are I suppose. I certainly wouldn't want it plumbed into the radiator when I'm towing in the middle of summer.

The radiator cooler does cool the tranny fluid. It also keeps it at a stable temperature. The aux tranny cooler instructions warn not to bypass the radiator cooler when installing a aux cooler.

I've got an auxiliary cooler (Ford Option) on my Falcon which is still plumbed into the radiator. It's less than 1/4 the size of the one I have for the F100, which was sized to be a complete replacement, not 'auxiliary'

Thought I'd better mention how I ended up hooking it up, I went to the cooler first, then put the fan temp switch in the cooler exit, then to the trucks own radiator cooler/heater & then back to trans.

ATF and transmissions are designed to perform best at stable temperatures, neither too hot or too cold, just like the engine. De facto hookup is to the original radiator cooler first. You could have had an extra cooler installed on your truck at the dealership when it was new. If you wanted. The instructions with Fords kit stated three times and in no uncertain terms that the lines were to be plumbed first through the radiator. And in the case of factory installed "tow package" coolers, all you have to do is look at one and see that's how they came off the assembly line. I don't presume to know more about it than Ford. And if anyone cares, Chrysler and GM happen to recommend and do this the exact same way.
If you think the little cooler inside the radiator is pushing your cooling system over the limit, IMHO you have cooling problems that need to be addressed that have nothing to do with the transmission.

You's convinced me, switched the hosing around tonight.
Its not that I have heating issues with the trans but I do long stints in low 4X4 with a heavy load, the firewall gets to 175deg I have no trans temp gauge but I'm guessing its not necessarily happy about it.
