I am planning on putting an automatic in my 65 F-100 with 240 I-6. I will eventually be putting 3.00 gears in it, and have been told automatics are the best for my situation. I have tracked down both FMX and C 4 automatics at a local wrecking yard for reasonable prices. Which does everyone recommend. I have been told both are good, but don't really know much about automatics. Any opinions, facts and info about these two trannys would be great.

Thanks

Tim, if your just buying a core to have rebuilt I'd go with the C-4. It's lighter, more recent, and easier to get parts for. Rebuilt with good quality parts it will last a long time. A properly built C-4 will handle tons of power.The FMX is a good tranny too, but the aftermarket supports just not there. Good luck
