Should I change my transmission oil?

So, would be very beneficial to 986 owners to have 1 sticky post that will state how often to change all the major items.

What do you think ?

I think it would precipitate another oil argument...........

Realistically, how and how much the vehicle is used plays into this; tracked cars and daily drivers need more attention than weekend toys. That said, in general, I would use the following:

• Coolant every five years, or when is shows signs of degradation (pH, freeze level, etc.)

• Engine oil and filter every 5 K miles
• Manual gear box every 30-40 K miles
• Tip fluid and filter every 40-50 K miles

And remembering to use the correct fluids, such as an engine oil with high film strength and ZDDP levels.
