Any advice on aftermarket large drain pans w/drain plug?

Mongo, we can use Mercon V now or even Mobil 1 ATF, which is what I'll be putting in next. The older TCs have a drain plug (I think they went away around '01). Just open the inspection plate and turn the engine manually until the plug shows up...

Otherwise, you can use the methond of draining the pan, refilling, pulling the fluid cooler return line, and running the engine for a minute or two until it starts to sputter, then refilling the pan, repeat running the engine/filling the pan until fresh fluid comes out the return line, then top off the pan with everything hooked up normally. This is described in greater detail elsewhere -- check the 7point3 site...

Filling transmission with ATF will pump the oil back into the TC automatically..when you start the engine.. keep checking the fluid level and filling until you measure full on the dip stick..

Thanks Izzy & Clint- I had my tranny rebuilt about 10,000 miles ago, but I did hit about 200 a couple of times. On synthetic I guess I could go 30,000 miles easy?

Depends how hot it got -- if 200* is as hot as your syn has been, then I wouldn't worry about going 30k.

I swear I dont have a drain plug on my TC but I could be wrong. I was under there looking when the Sonnax went in and you can turn the engine and never see the drain plug on the TC. By the way, how many quarts ATF

Those prices are cheap on the fans but will any of those mount on my truck?

We spent 3 months in Laughlin several winters ago, and both the grades out of there (back to US 95 in NV or over to Kingman AZ) are really tough on the old tranny. I found the biggest improvement in tranny temps for stop and go driving came from installing the updated Ford radiator with the built in tranny cooler. The Ford dealer in Lake Havasu was nice enough to do that for me in the fall of 2001 as free TSB just before my warranty expired. It's plumbed so that the ATF goes through the in-radiator cooler then through the air cooler. I've got a temp gauge in the return line from those coolers, and the heat transfer to the coolant is so good that I've never seen a tranny return temp higher than the lower radiator coolant temp of 165 F.

And as far as the fan, yes it would be better in get a cooler with a built in fan, just more money and probably more efficient too.. I already had a True Cool trans cooler mounted just behind the bumper/grill area so i just added the fan later. I had to attach some alum frame material to mount the fan..I have a pic if you want to see how it looks.. Like one of the other posts stated, your raditator is not plumbed for your trans oil. This is one reason why your oil runs hot in stop and go traffic.

Look under the front of the truck and find the lower radiator tank which has a large rubber coolant hose going to it on the passenger side. Next to and inboard of the large hose is a steel supply line from the tranny. The return from the radiator tank exits the tank on the drivers side and is routed under the tank and then up to the air to oil cooler and back to the tranny return. If you don't have it, you can get a kit from the dealer that includes a new radiator and the pre cut lines so that it's just a bolt in operation that looked pretty easy as I recall from watching mine being done.

I guess I am realy supposed to have a drain plug on the TC b/c my truck was built in jan of 2000 but the tranny in my truck was put in by the previous owner in 2005. (he had a ford remanufactured tranny put in) So does it stand to reason that ford would have replaced the TC w/ the new tranny?
