Mobil 1 synthetic Transmission Fluid

oldnavy · **Posted:** Mon Aug 21, 2006 11:32 am

Just checked with Mobil at the 1-800-Mobil25 (662-4525) number on website and was told the Mobil 1 was compatible and actually better then the Chrysler ATF+4 tranny fluid since it was a full synthetic oil. Still thanking about using the Valvoline synthetic someone mentioned on another thread.

For many GM, Ford and import vehicles. Approved for use in vehicles specifying:

Dexron III, Dexron IIIE, Dexron

Approved for H specification, the latest GM Dexron III performance level

Mercon, Mercon V

Recommended for Allison C-4 and Caterpillar TO-2 applications

Recommended for Chrysler automatic transmissions

I don't disagree, but why don't they list on the bottle that it meets or exceeds ATF+4 spec...instead of saying "recommended to chrysler vehicles". I guess because of the licensing issue on ATF+4.

Probably the $$$ D/C wants to allow the licensing. :wink:

According to this site:

http://www.imakenews.com/lng/e_article0 ... ?x=b11,0,w

Exxon/Mobil IS licensed as a blender. Why they do not offer a ATF+4 is beyond me. The article goes on to say:

"fluids meeting the ATF+4 specifications provide significantly improved wear protection, thermal stability and low-temperature fluidity while retaining the frictional properties required for Chrysler Group transmissions and torque converters....The ATF+4 specs require a specific additive system supplied by Lubrizol, and extra high viscosity index base oils. SK Corp., Petro-Canada and Motiva currently have base stocks approved for the fluids."

I remember a gentleman that was on the Dodge Cummins forums that rebuilt and modified the automatics behind the Cummins stating not to use anything other than ATF+4 in the Dodge trannies because of issues he saw with the failed units running other fluids. Personally with all the tranny issues I will continue using the ATF+4 products to avoid warranty problems.

So I guess I better get some ATF+4 tomorrow and change the transfer case fluid. Bummer, makes you wonder if anyone at these answer number ever knows squate about their product. I guess I could go with the Valvoline AFT+4 fluid and save about $4 a quart from dealer price.

Well, the thing that concerns me about using the M1 is warranty. The fact that M1 makes no mention of the ATF+4 spec on the bottle, and that they use a very general statement like "recommended for chrysler vehicles" should give some indication. Does that mean M1 recommends it for Chrysler vehicles, someone else, DC? When DC calls for ATF+4 spec for warranty coverage, and M1 makes no mention of this, and you consider all the issues these trannys have been experiencing, I wouldn't want to risk loosing warranty coverage for using what DC may consider improper ATF...even though it may be okay. We need someone to be a test bed to see if it really is better. I don't want to be that person though. Especially when the Valvoline ATF+4 product claims to be fully synthetic, does meet the proper spec, and is cheaper.

I wouldn't worry about M1 in the transfer case too much. For some reason I thought that the same transfer case in earlier models called for Dex III and I don't think any of the internals have changed. Again I could be wrong on that because I am suffering from CRS syndrom - Can't Remember S*** syndrom.

I've been running a syncromesh fluid in the t-case for about 30k now and not one single problem. If I remember correctly someone e-mailed New Venture (the t-case manufacturer) and confirmed that any quality ATF fluid will work. ATF4 is probably just specified for easy of service at the dealership-- one fluid does it all type of thing.

Yes with me also it is about the 7/70 warranty, so I will probably get some Valvoline ATF+4 here in a couple days and do a change out when we have a cool morning some Saturday.

If I am not mistaken ATF +4 is a synthetic so changing to mobile one would not be an upgrade.
