Here are some pics of autostick oil pumps, belhousings,and trans. I will try and explain how they adapt to a bus trans. A few of you have PMed me and asked for pics of how they are used.
Pic of autostick oil pump
Break away of oil pump---notice the three layers---- two pumps stacked together with a plate that has seals to keep two types of fluid apart from each other.
This one shows the front section of belhousing where torque convertor goes---a full automatic trans would have a pump located here instead of on front of eng oil pump.
Here you can see the inner flywheel. It is bolted to a shaft, supported by a bearing and goes into the torque convertor. The inside of the convertor looks like the fins of a turbo or jet eng. Those blades in a fluid bath is what drives everything. Depending on how much throttle, depends on how much slippage you have in the convertor up to a certain rpm. When you reach that rpm it becomes [locked up] and no longer slips.
Then the clutch, pressure plate and throw out bearing are seen inplace.
This last pic shows the top of a complete auto stick w/ servor that pulled the clutch arm in when you would put your hand on the shifter through an interupt switch. The convertor, belhousing,flywheel, clutch, pressure plate, throw out bear, clutch arm and an adapter are needed to make this work. I hope these pics will help! Don't mind the barn dirt.
