Title Page:
The used TH350 transmission is secured in the holding fixture and is mounted on the workbench. I have cleaned off a work area and rounded up the tools needed to take the unit apart for inspection. Disassembly begins with removing the pan and filter.

Top:
TH350 transmissions use a cable-operated downshift or “detent” valve located in the valve body. This valve provides forced downshifts with heavy- or full-throttle application for improved vehicle acceleration. The transmission still upshifts on the governor when the downshift valve is applied.
Middle Left:
Using a slide hammer, shock the pump loose from the case. It is best to use two slide hammers and work back and forth between them. Then, lift the entire assembly off the case and set it in a safe place for rebuilding later.
Middle Right:
Before bolting the pump halves together, measure them with a feeler gauge to make sure that the pump gears have some clearance. This should not be a problem unless a service replacement set of gears are used, or gears were taken from another oil pump.
Bottom:
The intermediate servo is located in the case under the separator plate. You do not have to remove it to install the shift kit. You must be careful, because it may fall out if the kit is being installed with the transmission in the vehicle.
