How do you check the transmission fluid on a 1999 Chevy Malibu?

For the answer to this question, look in your owner's manual. Don't have one then get one. You need an owner's manual for the maintenance schedule and for questions just like this. Sources for a manual are: Dealer, Salvage Yard, E-Bay, and many on-line sites. Here is one site. http://www.samarins.com/maintenance/manual.html
