Amsoil transmission fluid?

[buttugly]

Probably this has been argued many times. So I will ask, Is Amsoil good or bad to use in our 48ER's? :-{}

 

[DPKetchum]

Its used. Its advertised to exceed OEM specs. I've use and have used it in several G. M. ,Ford and Chrysler autos,just not a 48re.

Yes, you can use the Amsoil ATF in the 48RE's, as it meets the +4 spec.

Nothing against Amsoil but Mobil 1 is cheaper and the original there synthetic ATF is 5. 99/quart at autozone. I have run them all and Mobil 1 is the real deal. One to stay away from is redline I'm not sure what they are selling but it made 3 different transmission I tied it in shift horribly and cost more to boot. Mobil 1's product line can be used throughout or trucks systems and even carries the RIGHT ratings.

ttreibel is right mobil is cheap at the zone. but if you compare the price of Amsoils reg ATF. It is not much more. Now if you step up a grade to the Torque shift (which is based of the Allison/castro transsync oil. ) Which is rated the best oil for that transmission and worth a small fortune from the dealer. Amsoil is the only other oil that Allison will honor for warrenty work. Plus if Amsoil fails (due to oil failure)they will pay for replacement. MOBIL will not.

Buttug,

I don't know what oil you are running in the motor but again Amsoil is far superior. I once ran Mobil syn and ran a blackstone test for an extended drain and it come back with excessive metal wear and as soon as I saw that Amsoil went in. I have 37,000 on engine oil in a 7. 3 PS just changing filters. Oil is still clean as can be.

I do all my shopping by phone or online. The BIG BROWN delivers to my door. I like the Amsoil products,catalog and its delivered in 2 days.

 

[buttugly]

Thanks for the replies!!

I wasn't aware that Mobil 1 made an ATF that met the +4 specs... I looked for it for my T-case, but couldn't find it, nothing but Dexron / Mercon. So I used Amsoil throughout and couldn't be happier.

Considering Chrysler has never released the specs on their ATF+4 fluid, I would not put a lot of stock in what Amsoil claims.



Why would you want to use anything other then the ATF+4 from Chrysler as it is a full synthetic fluid.

 

[DPKetchum]

You sure ita a FULL synthetic and not a BLEND? Who's fliud is it? I happen to LIKE Amsoil products. I went from ATF+4 in another D. C. product and noticed from the get go smoother shifts and smoother lock of the torque convertor. Others HAVE posted a drop in trans temp over ATF+4.

 

[AK RAM]

Amsoil transmission fluid here for quite a while now. I beat on my transmission pretty hard and never a problem…. . yet.

 

[john3976]

Looks like Chrysler is being sued over the ATF+4 package, Chrysler refuses to release the formula.



Now I odn't know about you but I don't see how Amsoil can meet a spec that they don't have a clue as to what it is.



This link deals with Warranty issues as well involving the non use of ATF+4.

I agree with Ketchum. I changed my transmission fluid out with the amsoil. My truck(48 re) seems to shift smoother. coobie

Here is a TSB from Chrysler about ATF+4

Very good information on ATF Fluids from all the car makers, and a very good reason to stick with what the designers have speced the transmissions to use.



Makes you wonder how Amsoil can be a one oil fits all Automatic transmissions wonder. GM, Ford, Dodge, Toyota, Nissan and all the others have built and designed their products to work with a certain type of fluid.



As much as Amsoil wants you to believe, there oils are not a one size fits all as their dealers web pages would have you believe.

A little about Auto Trans Fluids from Chevron



Maintaining Your Transmission

These days there's no such thing as "normal" driving conditions. Heavy stop-and-go traffic, frequent short trips, trailer towing; they all put your engine to the supreme test and can take a toll on your transmission. Under these tough conditions, you can help your transmission run better and longer when you follow the vehicle manufacturer's severe service schedule and change the automatic transmission fluid at the recommended intervals (typically every 15,000 to 30,000 miles). Also, if you suspect that your ATF has oxidized or deteriorated between service intervals, you may want to consult with your local automotive service center.



Selecting the proper quality of ATF is not as easy as it once was. In the past, ATF came in two types: DEXRON®, MERCON® or ATF Type F. However, as transmissions have become more advanced, automobile manufacturers have introduced fluids specifically designed for their transmissions. Always check your owner's manual for the required type of ATF.



Here are the most commonly specified ATFs:



DEXRON® -III

This is a specification for General Motors vehicles, but many foreign manufactures specify a DEXRON approved ATF as well. DEXRON-III can be used in transmissions that call for DEXRON-IIE or DEXRON-II.

more info



MERCON®

Most Ford vehicles manufactured between 1980 and 1999 specify a MERCON ATF. ATFs that meet DEXRON-III requirements usually meet the MERCON requirements as well.

more info.



MERCON® V

Beginning with the 1997 model year, Ford introduced a higher performance level ATF with the MERCON V specification. Many Ford automatic transmissions from 1999 on will require a MERCON V fluid. The most notable exceptions are the E40D, 4R100, and CD4E transmissions, which still specify regular MERCON ATF.

more info



Type F

Type F is specifically designed for all pre-1977 Ford vehicles and some makes between 1977 and 1981. Effective March 1997, Ford discontinued administration of approvals for Type F fluids. However, there are still many vehicles on the road that use Type F. Type F and MERCON fluids are not interchangeable.

more info



ATF+3® /ATF+4®

DaimlerChrysler has had their own ATF specifications for many years, but as of 1997, Chrysler owners' manuals no longer list DEXRON as an acceptable replacement. ATF+3 is a readily available mineral oil-based ATF that is suitable in any application calling for ATF PLUS® , ATF+2® , or a Type 7176® fluid. Vehicles manufactured after 1999 require ATF+4® , a synthetic-based ATF only available through DaimlerChrysler.

Amsoil claims that you can go up to three times longer on their auto trans fluids then you can on OEM fluids:



Extended Drain Intervals:

AMSOIL ATF is formulated for extended drain intervals. Transmissions usually operate under severe service conditions. They are subjected to extensive idling, frequent short trips, cold temperature driving, sustained hot weather driving or trailer towing. When conventional transmission fluid is used, it should be changed every 15,000 to 30,000 miles. AMSOIL ATF should be changed at intervals up to three times longer than the recommendations of the vehicle manufacturer. [/B]
