Epic's Transmission Swap List of Questions, please help me prepare... 200 1991

1. I don't know the exact answer to your question about the gasket between the transmission and bellhousing. In the conversions I have done, I have used the bellhousing from the donor car. The older bellhousings I have encountered have a knock-out for the crank sensor. I broke out the thin plug with a pair of pliers if I recall correctly. I'm not sure what the purpose of the gasket would be. There shouldn't be any fluid in the bellhousing.

2. Again, there shouldn't be any fluid or pressure in the bellhousing, so the gasket doesn't really seem to be that important to me. If you can find it, put it in. Putting it in dry would probably be fine.

3. I don't know anything about this ring. Are you talking about the pilot bearing? I'm confused. Sorry.

4. The correct flywheel will have holes around its perimeter. I believe there are 58 of them. There is a blank spot where there is space for additional holes, but none are drilled. When the crankshaft is positioned at TDC, this blank spot should line up with the bottom of the opening for the starter. This method is different than what is specified in the Bentley Manual. It is how I aligned my flywheel after doing a search of the BrickBoard.

5. They say you should replace them. I reused mine. Make sure you torque them to specification.

6. If you want to be sure that you have a smooth clutch engagement, replace them both at the same time. Have your flywheel resurfaced. You might get lucky, but you'll be kicking yourself every time you drive your car if your clutch judders after you tried to save a few hundred dollars. I've taken both routes. I've was lucky the first couple of times. Eventually, my luck ran out, and I will never cut these corners again. Are you a gambler? (If you haven't done so already, you would be well advised to replace your rear main seal while the flywheel is off. It's cheap and easy to do now.)

7. Yes, the crossmembers are different. They have a slightly different shape and the M47 crossmember has rubber mounts where the crossmember bolts to the car. However, the position and alignment of the holes is identical. In the last swap I did, the M47 crossmember was badly rusted. I used the automatic crossmember and it worked fine. I would do it again. In the older cars, the crossmembers for automatics and manuals was the same. In both cases, they bolt to the car using a different set of threaded holes, though.

8. Use some variety of high temperature grease.

Hope this helps.
