Yes it is mercon. Many people use synthetic. Ford says mercon only, do not use synthetic. You decide, I used mercon.

Manual Transmission Fluid Type:

ZF 6-Speed

MERCON (R) Multi-Purpose Automatic Transmission Fluid XT-2-QDX

ZF 5-Speed

Synthetic Motorcraft MERCON (R) Multi-Purpose Automatic Transmission Fluid XT-2-QDX or MERCON (R) Equivalent

CAUTION:
Using a transmission fluid that indicates a dual usage MERCON and MERCON V in a transmission application requiring MERCON, may cause internal transmission damage. The use of any fluid other than the recommended fluid may cause transmission damage. Some fluid labels may indicate dual usage such as MERCON and MERCON V. These dual-usage fluids are not to be used in transmissions that use only the MERCON type fluid. These dual-usage fluids may be used in transmissions that require MERCON V use

That would make you a 6 spd. I also use mercon, that's what the book says. Usually Ford is O.K. on that stuff, but don't hold them to anything higher.

That's not correct. Ford says to use MERCON. They don't say anything about synthetic. There are MERCON synthetic fluids available and they are fine to use.

Only use mercon v

This is an old thread. Ford has since discontinued Mercon and mercon III and replaced with mercon V. Any combination type dex/merc or merc/merc III or anything other then mercon v should not be used for any trans that used to require mercon.

Ford did not discontinue MERCON III. MERCON III never existed. MERCON V did replace MERCON in 2006.

Jeffcham82. Welcome. I see this is your first post and a doosie pulling up a 15ish year old post to correct. Please use your search function because this has been beaten like a dead 🐴 resurrected and beat again.

These guys are a wealth of knowledge. Mark,who chimmed in, literally was part of Ford team for the development of the 4R100 , correct me if I’m wrong.. We certainly welcome another member that is an enthusiast.
May I suggest you start by introducing yourself over in the morning coffee thread etc.
cheers.
