I have a 94 Taurus GL that's been babied all its life--oil changes every 3K, no hard accelerations to the point where my wife screams at me for driving like a grandmother. It now has 136K on it; I've had it since 97K, the previous owners were meticulous. At 100K, I had the tranny fluid changed and what I, as I recall, was standard preventative maintenance. About 7K ago, it was low on fluid and required, as I recall, less than a quart--it wasn't very much in the scheme of things. Recently, when the car is cold, it sometimes makes a hard "thunk" when I shift from Park into Drive or Reverse. This is VERY sporadic, and doesn't happen at all when the car is warm. Performance-wise, the shifting is as good as it ever was. This in mind, is there any SOP on tranny maintenance that I should be aware of? I'm taking it in for an oil change soon and will have them check the tranny fluid level. Just want to know if there's anything else I should bear in mind. Thanks.

You can do a tranny service which is dropping the pan, changing the fluids and putting in new fluids. Your care requires Mercon, but you can use Mercon V.

The other option is to do a tranny flash. The car would be hooked up to a machine which pumps out old fluids and puts in new fluids. This is a 100% fluid replacement while the service is 60% as I recall.

Please,please dont do a machine tranny flush unless you want the tranny to fail soon after :( The reason is because the machine will force fluid out and they dont even change the filter and dont use Mercon V; use the replacement or equivalent to mercon III.
The safest way to do a tranny flush is at home and change the filter at the same time. I have done it in my 97 with over 195k more than 5 times and still running like new with the original tranny.
My only advise on top of DIY tranny flush and filter will be to install an aftermarket cooler or gen 2 sho tranny cooler.

Ford upgraded the specification from Mercon to Mercon V as I recall. Can someone confirm this?

Approx. 1996- 1998 and up Mercon V is TO BE USED. Merc/DeX III. No moe.
Use that ol'e DEX III in your P/S Pump.
the Encyclopedia states that Dexron III/Mercon ATF for AXOD-E (AX4S) 1991-1998

Now Are those Early Transaxles compatiable with Mercon V? IDK.

You are supposed to use mercon V on 1998 and newer models, use it in earlier trannys and get ready for a 2000+ rebuild. (don't beleive me Try it) :rolleyes:

I did. I had no problems. I started having problems now because of a Transmission range sensor and a screwed up solenoid.

Mercon V is a higher refined version of MERCON

I found this TSB.

ISSUE
MERCON® Automatic Transmission Fluid is being replaced by MERCON® V as a service fluid.

ACTION
Beginning immediately all automatic transmission / transaxle applications requiring MERCON® can now be serviced using MERCON® V or MERCON® Automatic Transmission Fluid or dual usage fluids labeled MERCON® / MERCON® V. After July 1, 2007, MERCON® Automatic Transmission Fluid will no longer be manufactured, therefore, availability of this fluid will only continue for however long it takes to deplete what remains in inventory.

SERVICE PROCEDURE

Service automatic transmissions requiring MERCON® with MERCON® V or MERCON® Automatic Transmission Fluid or dual usage fluids labeled MERCON® / MERCON® V

For proper fluid application on current and past model vehicles equipped with automatic transmissions I transaxles refer to the fluid usage chart. (Figure 1)
CAUTION AUTOMATIC TRANSMISSIONS / TRANSAXLES THAT REQUIRE MERCON® V SHOULD STILL ONLY USE MERCON® V OR DUAL USAGE FLUID LABELED MERCON® / MERCON® V.

CAUTION MERCON® SP, MOTORCRAFT PREMIUM AUTOMATIC TRANSMISSION FLUID AND MOTORCRAFT M5 ATFS ARE UNIQUE FLUIDS AND MUST BE USED IN APPLICATIONS RECOMMENDING THAT PARTICULAR FLUID.

USE OF ANY OTHER FLUID MAY CAUSE REDUCED FUNCTIONALITY OR TRANSMISSION DAMAGE.
CAUTION THE FUNCTIONAL CHARACTERISTICS OF FLUIDS FOR CVT TRANSMISSIONS ARE VERY DIFFERENT THAN THOSE OF OTHER AUTOMATIC TRANSMISSION FLUIDS (ATFS).

USE OF A FLUID OTHER THAN MOTORCRAFT CONTINUOUSLY VARIABLE CHAIN TYPE TRANSMISSION FLUID OR ONE LABELED AS MEETING MERCON® C WILL CAUSE FUNCTIONALITY CONCERNS AND INTERNAL TRANSMISSION DAMAGE.
CAUTION DO NOT USE AUTOMATIC TRANSMISSION FLUID SUPPLEMENTS, ADDITIVES, TREATMENTS OR CLEANING AGENTS.

Yes, all earlier tranaxles using Mercon can use Mercon V. The Wiki needs to be updated.

Ford announces a replacement for Mercon automatic transmission fluid


placed Sun, Jul 1st, 2007

QUOTE
Dearborn, Mich.--Ford Customer Service Division (FCSD) has announced Mercon V as the replacement for Mercon Automatic Transmission Fluid (ATF). Automatic transmissions, power steering systems, and manual transmissions previously requiring Mercon must, as of July 1, be serviced with Mercon V. "All transmissions that 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 that 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 that customers receive a better fluid." 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.[/b]
