SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components will
void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly recommend
that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components. We recommend that a
service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are normally available at automotive
dealerships and parts stores.
CAUTION:
Due to variations in the original TH350 automatic transmission adapters, it may be necessary to grind additional clearance
for the TH400 governor gear housing. It is best to test fit the original TH350 cast iron housing into the back side of the
TH400 case. Inspect the area to make sure that the cast iron housing does not interfere with the TH400 case. The photos
below illustrate the modifications necessary to allow for proper clearance. Do not force the two adapters together without
first inspecting. Without proper clearance, damage to the transmission case will occur.
