Referring more particularly to, the present invention red ices such shear loading on the bolts, by utilizing a wedge member or a tapered block, inserted and wedged into a spacebetween wedge surfacesand, and having oppositely facing outer surfacesandthereby placed into abutment with those surfaces, respectively, so as to exert a fore and aft directed force against those surface, denoted by arrows C, effectively acting to push those surfaces apart and counteracting the shear loads B. Such forces will also act in opposition to and reduce tensile loads acting on bolts. Tapered blockhas at least one passagetherethrough () for the passage of boltstherethrough, to allow insertion of those bolts into threaded holesand tightening those bolts to exert compressive forces against tapered block, denoted by arrows D, for holding that block in position. This may also be sufficient to apply a tensile load bolts, which are preferably at least generally longitudinally aligned therewith as shown. As a result, a force equilibrium condition can be achieved, which can significantly and predictably reduce and control shear forces acting against the bolts or other connectors for connecting axle housingto the side platesof chassis

An improved electronic control system for a vehicle transmission system having a plurality of sequential gear ratios allows the vehicle operator to selectively engage either a normal sequential gear ratio progression or a gear ratio progression that skips or omits certain low gear ratios from the gear ratio shift sequence. The transmission control system includes a microprocessor driven electronic control circuit that governs the transmission operation by selectively actuating, from a plurality of hydraulic clutch solenoid valves, a unique combination of solenoid valves for each gear ratio. Manually operable control means allows the vehicle operator to cause the microprocessor to select a software routine that omits certain solenoid valve combinations so as to progress through the transmission gear ratios during upshifts in the forward control mode at a faster rate, thus improving the acceleration of the vehicle in the low gear ratio range.
