Overfilling them will cause the gears to run in oil like a propeller. I would never overfil a tranny! Trust me you are doing it a disservice. Think of how many millions of them are running around and a bunch of them are LOW on lubricant... They still work fine. The hard shifting can be temporary, caused by new bearings/gears or whatever. I would take the fil plug back out and let her drain to the hole again.

Another you will get h/p loss from spinning in the deeper oil. Many others on this forum have lowered trannys and have no problems you should not either. as for dirty oil... I would change it completely. Perhaps the case came dirty from the rebuilders.

Do as BJ said and drain and refill, then see if it burns it again.
