    Kim have you run a transbrake before.
    I am told that when the brake is on and the motor is on the converter hard, that the fluid temp rises something like 50 degrees per second. It is very easy to get the fluid too hot and it will expand
    and possibly burp or overflow in some situations.

    I just put 1 in last summer. Had it for a few drives and it seems good. My buddy has a Cope tranny with brake. I refreshed it. A few years ago. It does not have the front drum drilled or the pump plugged. I will be checking it over later this month so I’ll try to remember to take pics. It had over 400 runs on it. Some with nos. Kim

      I cleaned up the rusty input shaft best I could. Do you think this pitted area warrants swapping shafts with the other one I've got??? Will this hold up to 600-650 hp? Keep in mind the hub on the clean shaft has the messed up clutch splines. Is it worth swapping the good shaft with the good hub?

        That rusted shaft looks like it has a manufacturing flaw to me and it looks twisted.
        I would not use it. Ideally another shaft would be best but if the choice is one of the two, I would use the one with the slight wear on the spline. It's not ideal but it probable will run fine. You could probably use a smooth honing stone and smooth down the marks or any burrs. IMHO

          How strong is the press fit on those input shaft/hub assemblies? Is it something I can get done with a 12 ton press?

              Yeah, I tend to over-analyze stuff.

              I did start cleaning up all of the parts today and started removing the old bushings. Any tips or tricks for removing the input shaft pilot bushing? What about the reaction shaft bushing? Those are the two I'm having trouble with without the proper tools.

              I usually take them to a tranny shop. They don’t charge much for it. Kim

                An improperly installed bushing is worse than a worn bushing.

                  I hear ya. Most of them were worn pretty bad, so I just bought the bushing kit. I'll probably take the stator and input shaft to the shop to have those ones done, since I can;t figure out an easy way to removing those particular bushings. The others are pretty straight forward.

                  Any preference on Kevlar vs. Red-lined for the rear band?

                  Kevlar is supposed to be better. It both will do a good job. More importantly is to have a solid front band when building for performance. Kim

                    Stupid question - Any idea what the small ball at rear end of the input shaft is for - the end for the output shaft pilot?
