The 545 had a cable actuated plunger, but my replacement trans, (MT643), has a cylinder with what I assume is a diaphragm with a hose connection on it.I have a 95 F800 with the 429 gas, and my trans is shifting kinda harsh and seems to be getting to high rpm's before shifting.7 Optional: U60 Input Gear can be replaced by S68 Input Gear to obtain output speed 92% of speed shown. Check the engine for a rough and fluctuating idle speed. Past experience with this condition told me that there was something wrong with either the output speed sensor, the connection or the wiring. Shift valves control hydraulic flow to the reactionary devices (clutches and bands) that drive and hold members of the planetary gearset Our large inventory of OEM Allison transmission parts includes a large line of new and rebuilt Allison automatic transmissions, and Allison Automatic transmission cores.
