Sorry if this is a redundant thread but I can't seem to find an accurate answer from EPC or StarTekinfo.

I would like to change the ATF in the transmission with the newer, synthetic fluid. What is the current part number (or interchange number) for this synthetic fluid? I have the 5-speed automatic.

Also, I would like to change the transfer case fluid as well and I am having the same issue. Can anyone provide the current part or interchange number for this fluid?

It seems every part number I'm find on-line is obsolete and calling the dealer is of no help since they will not provide me with part numbers.

Any advice would be most appreciated.
Thank you!
