Hi there,

My car is a 97 SL600 w/722.6 , Transmission fluid looks like oil (i.e. honey colored). Is this the "early" fluid or just typical mercedes synthetic?

Before you think I've lost my mind, yes, I am checking the transmission. Had to break the red seal and use the special dipstick.

The car has developed a "slight" harsh shifting condition from 3rd to 4th It has about 54,000 mi and I was thinking fluid change may help. When I change the fluid and filter I plan on having a peek at the solenoid pressure regulator valve spring as I know these can be an issue with the early 722.6's. Anything else I should look at while I'm in there that could be causing this. the problem seems worse when its cold.

If none of this helps should I take it in for an adaptation tweak? How is the adaptation stored? can a transmission loose its adaptation changes if the battery is disconnected for a while?


Thanks for any help
