• A typical 700R4/2004R installation costs between $1000 to $2500, requires many hours of labor, skinned knuckles and no small amount of thought, ingenuity and fabrication skills. We find a very large percentage of people who have installed these overdrives have no idea how they should behave or what they're actually capable of doing. With that thought in mind, let us offer you the following:
  ______________________

• Up shift at the appropriate time when using light throttle.
• Shift with a moderate firmness at light throttle.
• Shift firmness and delay should increase proportionally to the amount of throttle applied.
• Under specific conditions, all Th-700R4 and Th-2004R transmissions should perform the following downshifts:
  • Fourth gear to third gear
  • Fourth gear to second gear
  • Fourth gear to first gear
  • Third gear to second gear
  • Third gear to first gear
• They shouldn't shuttle back and forth from 4th (overdrive to third) while just trying to maintain the appropriate highway speed.
• Wide open Throttle upshift points should feel firm and occur at the correct RPM.
