wat is a corvette servo
Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
thanks, so it basically just makes it shift harder
Some more info:
The 'servo' in 4L60(E) (the auto trans used in VN-VE) speak is a hydraulically actuated piston that is used to stop the clutch housing rotating inside the trans. case in gears 2 and 4. It does that by pushing on a pin that wraps a brake band attached to the gear case tighter around the clutch housing, locking the clutch housing to the gear case.
A 'Corvette' servo is one that is used in some of the US versions of the 4L60E used in Chevrolet Corvette models and is, in essence, a bigger piston = greater apply force. The effect is to apply the band tighter, allowing greater torque to be transmitted before slip of the clutch housing inside the band under power, and, unfortunately sometimes, a faster rate of apply. Unfortunately because in planetary geartrains, like those that are used in auto trans., the element from the previous gear not required in the next gear has to disengage before the new element is selected. Just applying one element faster without also disengaging faster may cause two gears to be selected at once, even if only for a very short time. The result is components slipping. If other changes (in addition to the servo) are made at the same time, it can be OK.
