I have a few question for you fellow Chrysler Enthusiasts... I have a '89 New Yorker with a 3.0 and a Overdrive tranny. I recently purchased a Class II Hitch for towing around my trailer and bike. The trailer weights about 250lbs and the bike is about 600lbs. Can I successfully tow my bike and trailer with my vehicle or will I burn out the tranny? Should I install an oil cooler? Any other recommendations?? Thank you, Jesse
