Question 1
Anyone have a truly synthetic Mercon V? Want to stay away from dual rated.

Question 2
Anyone have a good method for Tranny flush? Dropping pan does not change fluid in TC. How about removing the cooler return line? Works on my SuperDuty. Which line is the return?

 

back to top. BTW that should be truly SYNTHETIC Mercon V

 

True Mercon V is a synthetic blend. You are correct, stay away from anything else!!!

no one has any help on Synthetic Mecron V?? I believe FOMOCO has a part number for synthetic Mercon V but need help

 

I looked at Motorcrafts web site and it didn't have anything about it being 100% synthetic.

 

As I have previously posted, true Mercon V is a synthetic blend....Motorcraft, Castrol, etc. ......

Full synthetic ATF is only rated for Dexron III / Mercon, NOT Mercon V

 

As noted, there currently is no such thing as 100% synthetic Mercon V ATF.

However, Mercon V (any brand) is a synthetic blend.

Mercon (not Mercon V) does have a 100% synthetic version.
