Hello all,
My 73 Gran Torino has a 351C. Pretty sure I have a flat spot in my ring gear. It grinds when I try to start the motor occasionally. When I pull the transmission should I press on a new ring gear or replace the flywheel that will have a new ring gear? I understand money plays heavily into this decision. I am leaning toward a new fly wheel and a new starter and rear main seal while I have it out. However, there are many choices for flywheel replacement. Any advice would be great. Thanks in advance for the guidance and wisdom. Mark

Well, it is a 3 speed automatic, I guess that would help. Silly me. It is the stock transmission.

then you'll need a complete flexplate, and the exact engine / transmission combo to get the correct flex. the ring gears are welded onto the flexplate not press fit like on a manual trans flywheel. i'd do some shopping around as the prices for the same part vary wildly, like up to $100 or more sometimes. SFI flexplates are stronger but tend to crack and fail sooner than OEM quality because they're thicker metal and resist flexing more than their thinner more cost effective cousins. check with Bulkpart to see if they can supply your flex, they traditionally show low prices http://www.transmissionpartsusa.com/searchresults.asp?Submit=Go&Search=flexplates if you get confused as to which is correct

Thanks,
I really appreciate the help. There is a auto mechanic shop at the Navy base near me that I can use that has a lift and such. I work alone so getting this done will be tricky. I plan to replace the rear main seal while I have the trans mission out. I hope to get it done in a day. Is that realistic? I may be able to get help from a friend of mine for a second set of hands. I will call the people in the link you sent. Thanks again. You are a great American. Mark

if you have a leak i'd make sure it's really the rear main before diving into it. valve covers and intake manifold rear china wall seals can be mistaken for rear main leaks. |

and that leaky if you're planning to do the rear main as a preventive measure skip it, you're more likely to cause a problem than to fix one that doesn't exist if it ever does leak just pull the motor and reseal the whole thing. you have to let the crank drop down to get the old seal out and a new seal in, it's harry in the car. |
