So searched the forums but get different views on what to use for transmission fluid....Mercon or Mercon V. What are you guys using? Thinking of using just regular supertech from Walmart but still don't know which one to use. Thanks in advance.

 

 

They still make Mercon rated fluid, I get it all of the time.

 

Ford hasn't issued a license since 2006. So anyone selling Mercon fluid is using their own recipe and standard and not Ford approved. Mercon V is the current spec.

 

I get it all the time at Walmart, it says on the jug for use in vehicles sevicable by Dextron 2, 3 or Mercon atf, and it specificly says not to use it in transmissions requiring Mercon V. I currently have about 3 gallons in the garage. They have it at most auto parts stores as well.

 

NOBODY makes a licensed MERCON fluid because there hasn't been a valid license to produce MERCON since 2006.

Once again, it's not licensed so who knows what specs it really meets? It might be the same as MERCON was, or it could be repackaged Type F. It could be ANYTHING because nobody is monitoring it. When Ford issued a license to produce MERCON the manufacturer had to submit fluids to Ford for testing. Ford determined if the fluid met the spec or not and only issued a license to the fluids that met the specs.

I recommend using MERCON V.

 

This is what I was referring to
https://www.walmart.com/ip/Super-Tec...allon/20573820
and you can get this just about anywhere that sells atf. https://www.valvoline.com/our-produc...s/dex-merc-atf

 

FWIW, BTS recommends Schaeffer All-Trans Supreme in the 4R100s they build.

 

Neither is licensed fluid and both varieties are different look at the viscosity of both on the PI sheets. They are both blended to their respective companies standards. They are not a licensed product. The only thing they are paying is a fee to use the Mercon Trademark.

Ford Announces New Replacement Specs for Mercon ATF

DEARBORN, MI – Ford Customer Service Division (FCSD) has announced MERCON V as the replacement for MERCON Automatic Transmission Fluid (ATF).

Effective July 1, the production and licensing for MERCON will cease. Automatic transmissions, power steering systems and manual transmissions previously requiring MERCON must, as of July 1, be serviced with MERCON V.

“All transmissions which recommended using MERCON ATF can now be serviced with MERCON V,” said Ron Romano, FCSD Service Lubricants Technical Expert. “MERCON V is a tighter specification which delivers better anti-oxidation, anti-wear and anti-shudder properties. It also provides increased protection against deposits, rust and corrosion. All of this helps ensure customers receive a better fluid,” said Romano.

All automotive repair professionals are encouraged to make the necessary preparations with customers to ensure a seamless transition to the appropriate fluids once MERCON is discontinued. FCSD does not recommend the use of any products that claim to be the equivalent of MERCON.

 

Whether it is or isn't actual Mercon spec I have used it in several transmissions, transfer cases, and power steering systems that spec Mercon and it has never caused any problems.

 

Schaeffer All-Trans excellent pricing on Amazon free shipping with prime ...
Used Valvoline transfer case lube that covered Ford XL-12 spec for xfer case lube.

 

When flushing my transmission the cheapest Mercon V I could find was Supertech from Walmart.

 

 

Yea.. Going cheap on a several thousand $$ device that could strand you in the icy cold or blazing heat is always the right choice!!
