Hey, so my boyfriend's SuperAir Nautique is having transmission problems. At times, it's making some "clunking" noises so we think the tranny is going to go out soon. However, there are no other symptoms. BUT, are we able to still use it until that happens? Will it cause anything else to get messed up if we do this? We want to go to the lake this weekend but don't want to cause any further damage. PLEASE HELP!
