i tried to change mine once and couldnt break the pan free fro mthe block with all the rtv they used. i suppose i could have if it were up on a lift and i had more elbow room. i bought a galloon of the atf+4 for 20.00 at dodge dealership. they parts guy sd that was enough. but then later on i was told it was not enough at a local shop, that i needed like closer to 12 quarts. im still not sure. i ended up taking to dealer for full flush and had pan pulled and filter change. 213.00 + tax - northtown dodge in amherst ny......
one interesting thing i noticed on my bill is they had fluid + additive listed on the invoice. i dont know if that is just a generic computer write up that goes on the invoice, or if they really put some additive like an antifoam in there. ive heard that all it needs is atf+4, but the dealer couldnt be wrong....yea right....
i couldnt tell a difference afterwards. then again my old fluid looked fine and may have only been in there 15,000 miles.
