i have a 06 with auto trans with 6,000 miles and would like to use synthetic oil for better protection an less heat to try and make the trans trouble free for as long as possible im not worried about the added expence an i plan to use the regular change schedule. my questions are will it void my warrenty my dealer does not know.also are there any possible draw backs to syn. oil in the trans. any replys would be appreciated.

The fluid put in at the factory is synthetic.

A friend of mine is a DC trans tech at a local dealer and he told me that the factory syn atf+4 is a extremely good oil and recommended staying with that particular oil and just changing or flushing on a regular basis.-Frog

Atf+4 Is Not A True Synthetic Oil

wrm

i was wondering about that because of the price it seamed awful cheap compared to the ones that say syn.on the bottle. now im getting confused again.

stick with the ATF+4, it's a good fluid. You can also use it in your power steering resevoir.

Its All Good

If you want to run synthetic ATF, then you could use AMSOIL, I use it and have had no problems.

does any one know a way to find out for sure if the factory fluid is syn. from reading tonight im still not sure. my dealer wants 90 dollars to flush my fluid an i furinsh the amsoil.that would end up costing me a couple hundred dollars for nothing thats why i am trying to find positive proof that the factory fluid is really syn.also i still dont no about the warrenty

contact a local amsoil dealer an ask him he will tell you that atf+4 is a good fluid but not full synthetic Why do you want to go to full synthetic anyway.

able to stand more heat before break down less ware at cold temps,better flow, personal peace of mind.

I have used Amsoil ATF fluid in 3 different Dodge products and it has held up very well in them and gave me no problems from its use. In fact I asked my local Dodge Service Manager and he is a by the book person and said that if I use Amsoil fluid in my 2006 it would be Ok to use and he said that is some very good fluid and he would not question it going in to my truck. Then today when I took the wife's car in to be serviced, a 06 Sebring, the SM said (with a smile on his face) that's some very good oil you put in your wife's car and all I could do is and say yes sir it is and he went on to say he is glad that I will take as good of care with her car as I do my truck

So my self I can't see why your dealer should say anything if you use it in your truck as it is a better fluid then what Dodge puts in it IMHO.

good to hear that thanks.
