id also ask the shop youre going to what kind of fluid theyre using
called a reputable shop in my area and got quoted 300$ less than the dealer only to find out they were going to use Wolf's head fluid which costs about 3$/qt..they also offered a 90 day warranty
I asked if they could use my fluid and filter which is ZF lifetime 6 fluid and superior in every way to the wolfs head and they said yeah but no warranty..im like what you gotta be kidding me!
So they drop whatever oil that "works" in every tranny in this world but with more expensive oil that is the correct one for my type of tranny they wont cover in case of damage..i decided to take my business elsewhere,...
