Local five star dealer's service manager told me his master transmission mechanic said that using synthetic transmission fluid will cause me all sorts of problems. The only one I can imagine is slipping clutches and slipping lockup clutch. Am I missing something here? Should I wait on a valve body with increased pressures and a better TC before switching to synthetic? :confused:
 
Say what? If your dealer told you this I think I would find another one. Only reason they would tell you this cause there afraid of losing a sell of ATF fluid and services on you.
 
Pretty absurd statement. I second the "find a new dealer" comment. Synthetic would do nothing but good for your transmission, better low temp flow, better high temp resistance to burning. It isn't going to make anything slip that isn't already slipping. What kind of "master" is he... Jedi master :D Doesn't sound like he knows beans about transmissions to me. I would also like to know WHY, and what problems exactly it will cause?

I think about 99% of the people on here are running synthetic. I know that when I switched to sythetic my shifting seemed to be a lot better. Could tell a big difference in the shifting when towing too.
 
I run the Pennzoil stuff that meets the DC spec. I doubt very much that there's anything at all wrong with using synthetic.

Oh, man, sometimes being a doofus really sucks. Sorry about that, guys! But he's still al fool for saying synthetics are bad!

The owners manual says "USE ONLY ATF+4"

Why would you want to risk voiding the warranty by using something else?

Yes, ATF+4 is a synthetic.

But, the other synthetics are not ATF+4
 
I don't want to contribute to another "oil war", but Amsoil claims that their ATF is Recommended for applications requiring the following specifications: ... Chrysler ATF+ thru ATF+4®...



I'm not sure if that can be interperted as "meets the specification for... ", but I assume that Amsoil would have to back their product by paying for any damage that is determined to be caused by the fluid used. Getting something in writing from them might be a good idea though.



Here's the link: http://www.amsoil.com/products/atf.html
 
No one has ATF+4 except Mopar. If you think all fluid is the same, just see how it shifts when you put ATF+3 in it.

And I don't think +4 is 100% synthetic, I have a feeling it is a blend. If it was synthetic, it would be $20. 00/qt like the gear lube!
 
How would they know. They don't do any type of lab work etc. I ran Amsoil syn. when I worked in service at a D. C. dealer. It was like SO!
