1962 - 1965 Mopar Mail List Clubhouse - http://www.geocities.com/MotorCity/3306/ shift kit/shift improver are the same thing... in a 904/727, the same valve body is used.. the kits entail removing the valve body, drilling an extra bypass with included template, enlarging the 2 main supplies, inserting a backflow restristor, changing kick down and gear entry settings, a few springs here + there... and its done!! in my experience, you feel a great improvement, though u dont feel the full benefits unless you use a better converter.. for more stall, in addition, i highly recommend the TCI rtf, for all applications, it is a [green] synthetic trans fluid, compatible with all types of fluid ,[not to mix, but with all types of trans requirements i should say] i have even used it in a fluid drive '47 dodge.. while i have the tailshaft off, i also file a groove in the yoke bushing for improved oil delivery out back.. but i dont think u r planning on removing the trans... but with out installing the hi-pressure spring in th front pump, [trans needs to be out] dont even bother doing the rest of the mods.. u need increased pressure to benefit from increased valve body flow, thats about it.. if you have any more ques, i will try to help jim ______________________________________________________________________ To unsubscribe, write to -unsubscribe@xxxxxxxxxxx Start Your Own FREE Email List at http://www.listbot.com/ |
