Sonnax Valve Body Reaming Fixtures

In certain applications there is no way to pilot a reamer to repair a worn valve body, forcing rebuilders to purchase new ones. This patented self-aligning fixture with specially designed tool kits allows these valve bodies to be repaired. The fixture provides an external rigid pilot bore for the reamer and guide pin. The self-aligning feature allows the fixture to be used on multiple valve bodies and valve bores. The fixture base is large enough to provide ample support for the valve body. Various transmissions locate some valve bores in the pump body rather than the valve body. These larger pump bodies do not readily fit onto the standard VB-FIX base plate. Sonnax offers an oversized pump base plate, VB-06, that allows large passenger vehicle pump bodies to be easily mounted and clamped to the VB-FIX for repair. Additional notes: * Patented, unique self-aligning device produces consistent, reliable results and eliminates the potential for reaming failures * Special tool kits have been designed to service a specific valve train bore, and must be used in conjunction with the valve body reaming fixture VB-FIX. Part numbers for these kits begin with an "F-" to distinguish them from the traditional Sonnax tool kits that can be used as standalone tools. * Contents: -- Base plate standard -- Clamp mounting plate -- Clamp plate round -- Outer races (2) -- Inner race -- Studs (3) threaded -- Washers (3) flat -- Wing nuts (3) -- Socket cap screws (4)

TransGo Automatic Transmission Solenoid Kits

TransGo Performance offers solenoid repair kits for nearly a dozen automatic transmission applications, including models from Mopar and GM. Transmissions often come with contaminated governor pressure solenoids. This results in complaints of wrong gear starts, as well as governor solenoid and sensor performance codes. The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older 'RH' series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure. Simultaneously, it monitors the feedback from the governor pressure sensor to confirm that the governor pressure is doing what it is commanded to do. When the solenoid sticks or is restricted, the computer notices that the pressure reading from the sensor does not match the desired governor pressure and sets a code which puts the unit in limp-in mode, resulting in 3rd gear start and no shift. These TransGo governor pressure solenoid repair kits contain everything you need to take apart the original equipment solenoids, restore the valve bore, then replace the spool valve, spring and cap with new ones. The repair kits include enough parts to rebuild multiple solenoids. The repair kits are available with or without tools. Order the model recommended for your transmission. * Corrects/Prevents/Reduces: -- Wrong gear start -- No upshift -- Governor pressure solenoid and sensor performance codes -- Limp-in mode
