Some TF-2 Questions

Tracey is right about the check-ball in position "R". This is probably more often in later VBs. What the check-ball does is reduce the orifice size that feeds the Low/Reverse Servo piston, enabling a more "gentle" application of the rear band when selecting manual low or reverse. I also leave this check-ball out due to the fact that when manual low or reverse is selected, the vehicle is more than likely stationary. The check-ball at position "C" reduces the orifice size that feeds the Forward Clutch, enabling a smooth shift into any forward range. I always replace this check-ball unless the vehicle has a very loose converter.
Cheers. Gaz
