Just bought an '03 CTS. First thing I'm doing is changing all fluids. Want to purchase a new transmission filter but I'm confused. If I look up a replacement on a site such as rock auto it shows that there are a couple of different part numbers for the same brand (mainly looking at AC delco).
AC Delco part # 96042545 or # 96041844 show that they are both compatible with my '03. Which one is accurate? I would consider other brands as well. Want to get this ordered now so I can get it done. Can anyone give me an exact part number for my '03? Thanks!
I bought mine from oreillys they only have one style I think but pretty much all kits come with the neoprene gaskets unless ordered online. Cadillac told me there is a number above the pan that will tell you which style you need. Guess they made 2 different kinds in 03. Mine wasn't the shallow mount. So see what numbers you have then call Cadillac to see which one you need.
They cannot tell you which one you need by the VIN or RPO. There is a tag on the driver's side of the transmission that will tell you. It should read either 3GAG or 3GBG. The 3GAG is the cheap one, which I believe O'reilly's carries. The 3GBG is the more expensive one and I believe it is dealer only for that filter.
