Receint purchase of 97 SL-320 and found some xmission fluid around the hose from the radiator. Went to check fluid level and found "NO" dip stick. Owners manual confermed this model/year has no xmission dip stick?? How do you conferm the fluid level in xmission?? Is there a kit to install same. I'am an old DIY'er and can do most things this side of engine or xmission work. Thanks for any input...Ron
