Six Speed Questions

[2002F3504X4]

Been reading posts on the 6 speed manual, and have some questions. My truck is an 02, F350, 6 speed manual, 4x4, 4:10 gears, dually. Does this transmission have a pump to circulate the fluid to a cooler? In heavy pulling conditions, does it need an auxillary cooler, or is the stock one good enough? Mine has 31K, on it and is working well, I am just trying to understand the truck a little better. Thanks in advance!

Your manual tranny should be air cooled, I have never seen a manual with a cooler before. You should be fine.

Thanks for the response. The transmission has metal tubing coming out of the case, that runs towards the front of the truck. I assumed that it some sort of cooling, maybe I am wrong? ...

The ZF6 does have a cooler and I haven't heard of anyone having heat issues with them. A manual tranny doesn't generated as much heat as an auto.

So it must have some sort of internal pump to circulate the fluid?

My bad, new to the ford tranny's my self, i am used to working on older models. You learn something new every day. Yes it should have some kind of internal pump for that i imagine.

Thanks to everyone for your quick answers. I can change a few parts, am no mechanic, but like to understand how things work.

I put larger cooler on my 2000 7.3, PSD with the ZF manual 6 speed.. Did not really effect trans. temp (lower) .... In my opinion the quality of fluid itself is more critical since its what carrys heat to the cooler which on my truck is mounted slightly in front of and below A/C condensor,, which in front of intecooler,,, which is in front of radiator,, which is front of me?? I think???

Yes there is a pump in the Zahn Fabrique 6 speed manual trans..

I have an '01 F350 with the ZF6, it does have an internal pump to route fluid to an external cooler. I've done several upgrades including an external full flow transmission filter and a temp gauge installed in the PTO plate. At first I thought the temp sensor was not operating as the gauge didn't read anything over 100 degrees until I had driven for 30 miles and the gauge finally showed about 110 degrees. I had drained and flushed the transmission and went back with Synthetic Mercon, keep in mind that it's about 20 degrees here and the windchill at speed will be well below zero. I installed the temp gauge only for when I tow, I have a 31' traveltrailer and want to watch my temps as well as my EGT's while towing.
