Start with the basics. The FMX is very sensitive to fluid level. Check the transmission fluid.

Smoke is never a good sign but it could simply be the result of a leak which goes back to my first point.

73 conv. 460, D0VE large valve heads, Performer RPM manifold, Voodoo 227/233 cam, Holley 950 HP carb, C6 trans, 3.25 trak-loc.

^ agree with the above, check your fluid levels. I had a trans rebuilt a few years ago, the shop did not refill the torque converter and it gave the exact same symptoms until they finally checked the fluid level and topped it off.

Good luck
Tom

It should be Type F -- not the modern fluids

And, check it with the engine running and the transmission In Park. If the transmission is cold the level should be at the add line, or a little less.
