The Adapter Plate kit will allow you to use Buick, Pontiac or Oldsmobile and Cadillac 200, 350 and 400 Turbo-Hydramatic Transmissions with a Chevrolet engine. No alterations are necessary and installation is easy and simple.
NOTE: On some Turbo 400 transmissions, the webbing located inside the bell housing may interfere with two of the adapter plate kit bolts. Webbing must be trimmed to clear these bolts.

Step 1 Position the adapter plate on the back of the engine with the attached nuts facing the engine. Align the “A” holes on the adapter plate over the engine dowel pins. (See Figure 1 for location).
Step 2 In the bolt holes marked “B” use the four (4) bolts supplied to secure the adapter to the engine. All engine bolts should be torqued to 35 foot pounds.
Step 3 Install converter and transmission using two (2) OEM bolts in location “D” on the adapter plate. Use OEM bolts in location “C”. All engine bolts are to be torqued to 35 foot pounds.
Step 4 Before bolting the converter to the flywheel, use a spacer between each converter bolt and the flexplate. Converter ‘pull-back’ to the flexplate should be between 1/8″-3/16″ with the spacers. Torque flexplate-converter bolts to 30 foot-pounds.
