Those are your trans cooler lines. 3/8" gas hose from AutoZone or CarQuest will do the trick nicely and you will want to replace the tension-style hose clamps with screw-type hose clamps. Just let your friendly counter-man know what you're up to and he will steer you in the right direction. Even better if you drive the VX there and he can take a peek...Best-o-luck, it's an easy fix but you'll want to top off the trans when you're done!
