    My tcase is making noise. Thinking about just rebuilding but i want lower gears i have 4.56s and a TH400 that i built and it just seems i have to give it alot of thottle to get up an opstical maybe it becuase the auto but i was thinking it be easier to change gears in the tcase. any one know of any one that makes a 4 to 1 for the 203 if tried researching it and i just can find doublers sooo im guessing probley not but ne help would be nice. I was thinking about going with Trans star for my rebuild kit ne others that you guys like????

    Wagoner Machine Shop makes a 3:1 for the 203. It requires machining the case for the larger gears and costs around a grand (including the machine work)

    How big are your tires?....just rebuild your case to stock and see if that helps, if not, then do the diff gears.
