This has been posted before, but I thought I'd go back and refresh my memory about the maintenance recommendations for the TKO trans. JCoop mentioned that the
oil in his tranny looked like new after 6,000 miles. Unless you track your car a lot, I'm guessing that you really don't need to worry about changing it for a long time.
"Maintenance
Recommended
oil change intervals should be based on specific usage.
In most cases a “fill for life” is adequate, while in severe applications such as drag racing, or road racing a more frequent fluid change should be prescribed. Excessive heat will cause most fluids to breakdown and ultimately cause damage to the transmission."
