Anyone using this ATF in their Excursion? I was considering the use of this fluid when I service my tranny. Just thought I would ask and see what experiences people may have had. Thanks.

 

I have used Mobil 1 ATF in several transmissions. It's great stuff!

 

Thanks for the reply. I read that you are an expert on auto transmissions, are there any special concerns with this stuff in the 4R100 trans in the Excursion? Thanks again.

 

Would a Ford Dealership put Mobil 1 ATF fluid in if you requested? What is it that the dealer uses if not. I am going to have the transmission service in about 5,000 miles and I would be interested in going to Mobil 1. I want them to pull all the fluid through and then refill it though. That is how it was explained to me at the dealership.

No. Just flush out the old and install the Mobil 1.

 

Thanks again for the reply. What about using it in the power steering system also? It calls for Mercon ATF, any experience with that application? Thanks again...Ken.

 

If it calls for MERCON ATF, Mobil 1 is a good choice. It's an excellent MERCON rated ATF.

So would a Ford Dealership use the Mobil 1 if you requested it or do I have to go somewehere else to have it done? Guess I could do it myself, but I am not too confident in being able to get out all the old fluid first. I suppose a typical transmission shop would have the equipment to pull out all the fluid like is done at the dealership.

 

My dealership will put in Mobil 1. You gotta supply it to them.

Shop around. Swappin' fluid isn't too difficult so long as they got the machine. But the prices vary drastically (at least here in my area)

 

O.K. I got it done today. I drained the tranny and torque converter, installed a new filter, and filled her up with Mobil 1 ATF. Also drained the transfer case and power steering system and filled both of those with Mobil 1 also. All total it took almost 24 quarts of fluid, had to waste a little on the flush. Let you guys know later on what differences I may notice...Ken.

 

What type of fluid does the dealership typically use? Is it a synthetic blend or dino? Thanks.

 

[updated:LAST EDITED ON 28-Oct-02 AT 09:06 PM (EST)]The factory specifies Mercon fluid for my Excursion, so the dealership would probably install a Group II fluid. I don't think it would be a synthetic or a blend unless you specified one and paid the extra cost of the fluid. If I am wrong on this, please, someone let me know...Ken.

 

OK I have often wondered about special oils for the tranny. In a motor reduced friction is a great think but your AT uses friction as the main drive. If you reduce friction you induce slip and increase heat which is the greatest enemy to an auto. How would a synthic help? Arn't they mainly designed to reduce friction or do they add friction additives for the trany?
I have always stuck with what was reconended and never had problems and I am to chicken to switch. I do run Mobil 1 in the engine of all my cars and trucks though.

 

Mobil 1 synthetic ATF *IS* a recommended fluid for the Excursion automatic. Ford recommends MERCON fluid, and Mobil 1 is a MERCON fluid.

Synthetic MERCON fluid has EXACTLY the same "slipperyness" as non synthetic MERCON.

MERCON is a specification for properties of automatic transmission fluid. For a fluid to be licensed by Ford to have a MERCON label it MUST meet the specification. Coefficient of friction, or "slipperyness," is tightly controlled.

As long as you use a fluid that meets the MERCON specs, but is NOT dual MERCON and MERCON V rated, you will be fine. Ford requires that the E4OD and the 4R100 use only MERCON, not MERCON V or a fluid that has both MERCON and MERCON V ratings.

 

What is Ford MERCON®V and how is it different from MERCON®?

Ford introduced a new ATF specification for service fill called MERCON®V. MERCON®V ATF addresses anti-wear and anti-shudder protection above the existing MERCON® fluid specification. MERCON®V is designed for optimum performance in Ford’s newer automatic transmissions with electronically controlled and modulated torque converter clutches. The first transmission models to convert are found in some 1997 Ford trucks. The 1998 model year has seen the conversion of many more transmission models. Refer to the Pennzoil Lubricant Recommendations and Capacities Guide or the owner’s manual for exact applications. Not all MERCON®V and MERCON® ATF’s are interchangeable. These are two separate specifications licensed by Ford. Pennzoil® MERCON® V ATF does meet both specifications and is licensed as such. There are currently fluids on the market that meet one specification but not the other.

Problem: AMSOIL INC. has been informed that some AMSOIL Dealers and their customers have experienced problems with their local Ford Dealership service department when bringing in the new AMSOIL Universal ATF for installation in their Ford vehicle transmission. They have been told that: A) You cannot put a Mercon V labeled transmission fluid in a Mercon application. B) That you cannot put a Mercon labeled transmission fluid in a Mercon V application (this is true). C) That you cannot put a dual usage labeled ATF product in the Mercon application or the Mercon V application. Since the new AMSOIL Universal Transmission Fluid is labeled dual usage, recommended for both Mercon and Mercon V applications, some Ford Dealership service managers are telling their customers that if they put the AMSOIL Universal ATF product in their transmission it will void their transmission warranty.
Answer: At least one oil company’s ATF product with a Mercon V rating does not also meet Mercon performance requirements. This has apparently caused a great deal of confusion about allowing Mercon V ATF to be back serviceable in Mercon applications. The AMSOIL Universal ATF has been formulated to meet or exceed both the Mercon and Mercon V specification, as well as G.M. Dexron III and Chrysler ATF+4. It is fully supported through documented testing. It is recommended for and can be used in ALL of the applications listed on the label. PERIOD.

I found the same thing listed on many sites, there are some fluids that meet both specs, these can be interchanged w/ no problems, there are some that do not meet both specs and these can not be interchanged.
As for mobil 1 on it's site is says mercon not mercon V? I do not know if it meets both or not, as stated I use their motor oil b/c I feel it makes a dif by reducing friction, in an ATF I do not see how a synthetic is any better than a petro based. Remember oils problems come more from being dirty than anything else so change intervals should never be increased just because it is a syn oil, the oil is still dirty and contaminants are still present.
