Hi everyone...first of all, let me tell everyone how excited I am that I finally have the 351C in my 1973 convertible running like a deer. I was having fits with hot starts, and after talking to people on this forum, etc, replaced the Holley street dominator single plane intake manifold with the Edelbrock performer (dual plane designed for idle to 5500rpm) along with a Holley street avenger 670cfm carb to replace the Edelbrock under series carb. The difference is impressive with how well it runs. But now I have another issue. The transmission is slipping. For quite some time the car will go into reverse when it is cold but not drive. You have to let the car warm up for about five minutes before it will go into gear. A local recommended trying some stop slip to see if it would help, and it did a little, but not much. The local shop thinks it is an FMX transmission, but I can't find the ID tag which would tell me. Would anyone mind letting me know where I could hunt it down?
Besides that, does anyone have strong feelings about rebuilding the transmission versus an alternative, such as putting in an AOD transmission. I talked to Broader transmission in Texas after seeing them mention in several places, and he made it sound like quite a bit of modification to make it fit. The local shop that I deal with seems to think a rebuild of the existing transmission (be it the FMX, C4 or C6) along with new gears in the rear end would be all I would need. I'm not building a race car. I want something that is fun to drive and will get up and run from a stop. As always, any input would be a great help! Thanks again, Tyson
