Follow this thread and the threads it links to:

(if you race you want to change all your fluid, see near the bottom of post #10 of that thread).

 

I will change it prior to race season.

 

your wont see any metal shavings unless you drop your pan and look at the magnet.

 

If you have alot of money in the converter and trans, and the car is raced alot, the reason you should be into it once a month is to make sure the trans is not leaving metal, brass, or aluminum deposits in the pan. I'm into mine once a month. If you catch it early, you can save big bucks. With all of the hard launches and firm shifting metal is being pounded like a hammer on a nail. Something can give at any moment. I agree with Matt. $20.00 and a little time is all you need to save thousands.

Once a year for street/track car that sees about 5K miles/year.
