DUTCH:
There are some OBDII codes (PO codes) which will present themselves from the transmission in the engine control module, but on out test equipment the fault simply reads "see ETC", which means the fault is actually transmission related. I am unsure what the ramifications of these types of codes would be to a generic scan tool. I would assume a good enough generic scan tool would also allow access into the ETC for code readings. Or possibly a generic scan tool would give a fault description of the problem, rather than a reference code only. It's easy for us to simply switch from the engine control module and pick up the diagnosis at the ETC, maybe this works differently on a generic scanner.
On the condition of the fluid, you know I try to follow MB guidelines on things and I'm sure you know there is no replacement recommendation on the 722.6. If he bought it at 32,000 miles and is still under lets say 50,000, I really don't think the fluid is ready to be changed yet. i know we've had discussions about this and many will disagree with my view. I really think changing the fluid at anything much less than 100,000 miles really isn't helping that much.
