545rfe filter and trans fluid

Like Tinmannz says, watch off brands. I worked in the industry, and go for an oem brand, not something off shore.
Filterteck, and Sealed Power are two OEM brands that come to mind. Also, why not check with your local dealer and see what they want for one.
Don't let price be your only guide, ' cause you only get what you pay for.
I know times are tough for all of us, but spending a hundred bucks for a quality filter and quality oil is a whole lot cheaper than redoing you transmission.
