I'm playing with an '89 Tl 3 spd. automatic behind a Tl 2.5L out of a LeBaron GTC moving a 2250lb Plymouth GT Scamp with 5X100 15s. What is the best top gear that Mother made for that transmission to keep the RPM's down? I'm looking for a highway gear, not a 1320' gear. Something that will make the 500 mile trip to Carlisle in under 8 hours even with a few stops and maybe even a stop for a fast driving award. Thanks for any information, Jer
