1994 Dodge Ram

SLUGGISH!! shifts fine but has too sluggish on the freeway. Not sure if it had anything to do with me changing plugs and cleaning throttle sensor or torque converter. 1995 dodge ram. Single cab 4x4 with solid axle up front. New diffs. New transfer case. New trans. Didn’t replace one tc and it gave… 5.9 GAS engine solid all new fluids. External trans cooler. Solid truck I use as a daily for work. AC blows very cold. Nice exhaust system. LED light bar on top and HID headlights. Ac good. power windows work good. major cons are paint (expected for a 30yr old truck) dash is cracked (same as every other 2nd gen ram) its on PNO Clean title pink slip in hand. Willing to trade
