Thanks DC. I put a Magnefine filter on the power steering. I had thought about putting one on the transmission if I could not find a better in pan filter. The car has 118,000 miles and seems to be in great shape. The transmission was "serviced" whatever that means by the dealer at 15,000 miles. Not sure why it would need anything at 15,000 miles?? The fluid looks good. I plan to change all the fluid in addition to just draining the pan. I also am a fan of frequent fluid changes for the transmission. (cheap insurance).
Is the factory transmission pan gasked re-useable or will I need a new one? Can I just back flush the filter when I have the pan off?
Don't take the pan off unless there needs to be further service, Don't overthink this . Never reuse a gasket.
The reason I asked about the gasket is some gaskets now are designed to be re-used according to the manufacturers service manual.
I don't understand why not to clean or change the filter. A filter will only hold so much stuff and then they restrict the flow causing low pressure and damage to the transmission. I don't want to do unnecessary work but transmission repair is not cheap.
