i was wondering if u guys can help me, i have had my lude for a while and i recently rebuilt the engine, but for a while now after i fixed the car the cars first three gears seem heavier and they jump rpm's(auto tranny) i was wondering if i should replace the tranny, or change the car to manual, can u guys give me an estimate of around how much i would need to fix my car, its a necessary vehicle for me and ive invested too much money to just junk it...
