Steve Mutter Posted April 19, 2007 Share Posted April 19, 2007 what kind of fliud does a 6 speed take,the tag is missing off the trans and the book said mercon 3 BUT I don't think that right? Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted April 19, 2007 Share Posted April 19, 2007 Mercon 3 is correct. I strongly advise mercon synthetic though. It discipates heat alot better and flows better in the cold weather. Seven litre capacity. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 19, 2007 Share Posted April 19, 2007 I thought I remembered that diesel applications required synthetic mercon so went a lookin. The older transmissions did according to the manual but all I can find on the 6-speed is: MERCON® Multi-Purpose Automatic Transmission Fluid XT-2-QDX (US); XT-2-LM12 (Canada) I also agree that synthetic might be the better choice for the diesel applications due to the higher torque values.

DwayneGorniak Posted April 20, 2007 Share Posted April 20, 2007 If you look in the workshop manuals in specifications for manual transmission, you will find that the ZF-5 speed took mercon synthetic in diesel applications. The ZF-6 has a pump and cooler which is the reason they downgraded the fluid. But as I said before, the synthetic discipates heat alot more and up here it doesn't gell in the cold weather. We use the synthic in power sterring systems as well. It was a fix that hotline came out with in 1995 for the Windstars mostly, but also for all ford vehicles blowing the return lines off due to gelling. 4R100's: same thing. They would gell and self destruct. We flush 4R100's up to fully synthetic, and the people who have installed trans temp guages cannot believe the reduction in temperature when towing. Just a little education based on experience. Quote Link to comment Share on other sites More sharing options...
SteveS Posted April 20, 2007 Share Posted April 20, 2007 When I owned a ZF6 I changed the fluid with synthetic (was probably Amsoil) and notice a considerable improvment in the shifting ease and smoothness. Quote Link to comment Share on other sites More sharing options...

DwayneGorniak Posted April 20, 2007 Share Posted April 20, 2007 I run synthetic in my ZF-6, T'case and power sterring system as well. My ZF shifts beautifully. Quote Link to comment Share on other sites More sharing options...
