Engine/Transmission (1994 - 1998) survey/ oil change

[JWaters]

My dealer has offered me a free oil change for the service servey that DC sent me to fill out about service on my 03 Hemi, well I the service manager today about changeing my fluid in my trans and rear of my 96 dually instead of the free oil change because I do that myself. He told me sure bring it in saturday and they will change the trans fluid and rear fuild free just for giving them a good servey. Now the question is what came in my truck from the factory? Syn or regular 90w, I know the trans has syntorque, but what about the rear end Dana 80? what does it have from the factory in 96? It is limited slip. I think I am getting off way better than a oil change with this deal!...



thanks for the help.

It probably has regular 85w-90 in it, but they will probably add 85-140 syn if you ask and really think you need it.

They buy their oils in bulk, even the Syntorx is cheap for them.



Hope you trust your dealer. I don't and have always felt that the freebie oil changes they offer is just a way they use to get unknowledgeable folks in so as to find something else to charge them to fix whether it needs it or not.
