So I recently bought one of Michaels trans filter kits, which I plan to install this summer. Right now the car is running fine, I just figured it was good insurance. After reading about some of the other issues people have had, I was wondering if it could be worthwhile to replace the trans computer (governor) as well? At $300 it's not cheap, but beats the price of a trans rebuild. Do these fail often enough with catastrophic results that it's worth the investment?
