Q: Need tips on preventative maintenance for my transmission

asked by on May 13, 2016

My car has 135,000 miles on it. As far as I know, the transmission is in good working order. The owner's manual doesn't have any recommended maintenance for the transmission. It says that it is optional to change the oil after 100,000 miles. I like to do maintenance/repair on my car for fun, and for peace of mind. Would it be worth it to buy some high quality transmission oil? What else could I do for the transmission (as preventative maintenance)?
