Claims
- 1. In a transmission system having a casing defining transmission oil passages to various apply units (clutch plates and clutch bands) and having a valve body with passages including shift valves interconnecting certain ones of said passages, and wherein there is provided a separator plate between said valve body and casing for routing oil between various ones of said passages to provide hydraulic oil pressure to various given ones of said apply units as a result of movement of said shift valve in response to changes in oil pressure resulting from changes in the transmission shaft speed and shaft torque to thereby automatically shift gears in said transmission, the combination of said valve body and casing with a laminated separator plate means for substitution in place of said separator plate to recalibrate the operation of said valve body, said laminated separator plate means comprising:
- (a) a first plate having various openings of given dimensions and positions;
- (b) a second plate; and
- (c) a third plate having various openings of given dimensions and positions similar to those on said first plate sandwiching said second plate between itself and said first plate, said second plate having some openings of given dimensions and positions similar to those on said first plate and including one other opening of a diameter such as to change the oil flow rate between at least one passage in said casing and valve body whereby the time period between the start of a given shift and its completion is recalibrated to a different time by said separator plate means.
- 2. The subject matter of claim 1, in which said second plate additionally includes a channel positioned to connect two of said transmission oil passages in said casing together to thereby result in application of oil pressure on two areas of at least one of said apply units simultaneously whereby the time period between the start of a given shift and its completion is recalibrated to a shorter time by said separator plate means.
- 3. In a transmission system having a casing defining transmission oil passages to various apply units (clutch plates and clutch bands) and having a valve body with passages including shift valves intercepting certain ones of said passages, and wherein there is provided a separator plate between said valve body and casing for routing oil between various ones of said passages to provide hydraulic oil pressure to various given apply units as a result of movements of said shift valves in response to changes in oil pressure resulting in changes in the transmission shaft speed and shaft torque to thereby automatically shift gears in said transmission, a combination of said valve body and casing with a laminated separator plate means for substitution in place of said separator plate to recalibrate the operation of said valve body, said laminated separator plate means comprising:
- (a) a first plate having various openings of given dimensions and positions;
- (b) a second plate; and
- (c) a third plate having various openings of given dimensions and positions similar to those of said first plate sandwiching said second plate between itself and said first plate, said second plate having some openings of given dimensions and positions similar to those on said first plate and including a channel positioned to connect two of said transmission oil passages in said casing together to thereby result in application of oil pressure on two areas of at least one of said apply units simultaneously
- whereby the time period between the start of a given shift and its completion is recalibrated to a shorter time by said separator plate means.
