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.
22. Install new Advance Adapter plate to the back of the engine using the original bolts that were used with stock bellhousing.
23. Install flywheel and check the alignment pin for correlation with flywheel marks.
24. Install starter motor after modifying to fit the Advance Adapter plate and double check engagement into flywheel assembly. The
shroud area of the starter motor will need to be modified for the new position in the steel plate.
25. Install clutch assembly using clutch alignment tool. The clutch disc must be a Chevrolet or Midway clutch No. 383303. This
clutch has a 1-1/8" 10 spline. The original Toyota clutch disc should not be used with the NV4500 transmission.
26. On the inside of the vehicle, cut a 5" diameter hole, 5-3/4" center to center, back from the original transmission tunnel hole for
the new shifter location.
27. Trim out the excess sheet metal at the rear of the tunnel area. This will provide extra height for the rear of the transfer case
assembly.
28. Install the new bellhousing assembly as illustrated in the diagram. A new clutch fork and clutch fork release bearing assembly
have been provided for the bellhousing.
29. A new GM backup switch, Part No. 12085485 can be installed into the top shift cover assembly of the new transmission. This
backup switch will be compatible with the original Toyota assembly.
30. Install the transmission and transfer case assembly onto the new bellhousing.
31. Install the clutch slave cylinder bracket No. 716288, to the driver's side of the bellhousing. You may have to move the slave cylinder
from the passenger's side to the driver's side which will require making a new slave cylinder hydraulic line.
32. Install the dust shield to the front face of the bellhousing. Modifications may be necessary for clearance.
33. Install the transmission shifter. You may want to heat up and reposition the shifter handle depending on driver's preference.
The original boot assembly should work if desired. The old tranny hole should be covered to keep heat and elements out of
the vehicle. A 5-1/2" square piece of sheet metal should work effectively.
34. The transfer case linkage can now be assembled at this time. Note that the shifter coming through the floor should be lengthened
if the original position is to be retained. The factory boot can also be reused.
35. Hook up the battery and starter cables.
36. The exhaust system may need rerouting due to the clutch linkage location.
37. Drive shafts should be measured and recut to the appropriate lengths.
38. Speedometer cable should be lengthened.
39. Emergency brake cable should also be lengthened. B.T.B. can supply new cables if necessary.
40. Fill transmission with the appropriate fluid.
