Hey,
So I'll be doing scheduled 20,000 mile Transmission fluid change in the sable soon. I'm Debating on what to use. I know chevron makes excellent products, How about there Dexron/Mercron Transmission Fluid Is it A group III Just asking for Some opinions and Facts.
Thanks

I would use either Mercon or Mercon5 type. Your tranny probably had regular Mercon in it from the factory, but Mercon5 has come out since and IS better. Havoline makes some that is semi-synthetic. Expect to pay $3+ a quart for it.
Hope this helps.
On edit: I would stay away from anything that claims both Dextron and Mercon capabilities. I personally just don't think it would work as good as Mercon5.

The tranny calls for Mercron. Can I use a Mercron V Rated in the transmission. Will it hurt.
You see the car has 120,858 miles on it. We had the transmission Replaced at 100,000 miles with on from the ford factory 24,000 warenty. So basically saying it's a new tranny and I want this one to last longer than the last one. So what would be My best bet a Regular mercron like chevron or a full synthetic Mercron like Mobile 1 or mercron V.

Horse puller were did you find this Info ( Just Intrested) and I can put Mercron V in a mercron Requiring Tranny right. So maybe a Brand Like Chevron or Castrol is that a good Idea.

1999 5.4 L ford expedition 4x4. with the 4R100 transmission. The dip stick says Mercon ATF. In the owner manual "Refer to the dipstick for the type of transmission fluid required. 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."
I am not an expert, just doing simple maintenance on the side. Please explain. Thanks.

And to add to the point that tradingden just raised, I'm not sure I agree with Havoline's broad statement regarding the advantage or even suitability of using Mercon V in an older tranny that was designed for Mercon.
Yes, Mercon V is recommended for use in the AODE/4R70W tranny (all years) due to "shudder" issues, and I'm sure that on a case-by-case basis some Techs might advise customers to use it in order to address a particular issue, but other than that, Ford says NOT to use Mercon V in '96 and earlier trannies.
As I understand it, there is a good reason not to use Mercon V in older ATs. The clutch material prior to '97 in FWD vehicles is not designed for this type of fluid nor its "special" additives. Throw in the already-finicky nature of the AXODE tranny in the '94 Sable and IMHO it's not worth straying from the original spec.
Stick with a good Mercon-rated fluid like Castrol Mercon. If you want synthetic, go with Mobil1 ATF, which is Mercon rated.
Just my .02.

So you guys are saying that transmission fluid is not backwards compatible? No argument here. I thought it was and the oil company data seems to indicate that. I guess "Always check your owners manual to determine the proper automatic transmission fluid for your transmission" is the disclaimer.
Is tradingden quoting out of his owner's manual? If so, I'm wondering how a manual printed in 1999 would know what specifications Mercon V would meet in 2003.

Ford does not recommend using Mercon V in transmissions prior to some 97 models. The reason given is an incompatability of this fluid with older clutch material. It is believed that this is not a problem with transmissions from 96 on and earlier transmissions that have been rebuilt with all new clutches in recent years.

ISSUE
A new automatic transmission fluid (MERCON V) was introduced in 1997 for use in some Ford, Lincoln and Mercury vehicles. This new MERCON V fluid is not used in all applications and is not interchangeable with others transmissions fluids that are currently used. Using the incorrect fluid may cause transmission or transaxle concerns...
....Ford Motor Company uses two automatic transmission fluids in the transmissions now being built. Either MERCON" or MERCON V automatic transmission fluid may be called for, depending on the type of transmission and the year the transmission was built. Although both fluids are excellent, they exhibit different properties and should be used only in the transmission for which they were designed. The vehicle owner and rebuilder should replace fluid with the type printed in the Owner's Guide and on the automatic transmission fluid level indicator. Refer to your Scheduled Maintenance Guide to determine the correct service interval. Failure to use the recommended fluid may affect transmission performanceand durability.

So the distinction between the two fluids is expressly acknowledged by Ford. That is one reason why I am not a fan of those "multi-application" formulas which supposedly cover Dexron, Mercon and Mercon V all in one bottle. Another reason can be found if you search the archives of this forum and locate a thread containing my post describing how I had a less-than-favorable exprerience using a muli-blend ATF product myself (my 5R55E Ranger tranny requires Mercon V).

Well if my Recitanly new reconditioned tranny I got From ford and had a ford dealership install it from 2001 should the material be alright or not.
Maybe just a full synthetic Mercron Like Mobil 1
