Indeed. I wish you had invented them a couple years earlier, so my first transmission build could have had them. My current one has them, and so far, so good.

I guess I wasn't clear with how I phrased that. My old trans (which blew up from broken trim springs) didn't have the MikeL springs, because he hadn't invented them yet. My current trans does have the MikeL springs, and they are working great.

Can I ask what the C2 Hub is and does?

It connects the C2 clutches to the P2 planet. They are know to strip the splines because they are made of soft metal.

Is the stock Allison input hard enough, that it breaks clean enough, that it'll actually come out?

I know my brother's 4R100 builder tried and tried to get his broken input out, but it just wasn't having it. It was hard enough you couldn't drill / tap it, but apparently not so hard that the splines didn't deform just a touch inside the converter, effectively locking it in place.

Out of curiosity, what in the tuning causes the C2 hub to fail? A tie-up where the C2 is applying before C3 releases? Or just a harsh shift and resulting shock load?

A harsh shift is a tie up. Not knowing how to play with fuel tables will take out a P2 planet and C2 hub on the 3/4 shift.

Ok, transmission is ready and about to be installed. I was reading on here in another thread which I cant seem to find at the moment, about when you mate the Flexplate to the converter, extra precautions you take to ensure you don't do something wrong or risk a failure down the road.

Mike, can you give me any of your pointers on the reinstall of a built transmission please. I believe it was one of your posts I was referring to. ANy help would be greatly appreciated.

First, there is one square hole in your flex plate and it should be aligned with the starter opening. Turn the flywheel till it lines up. After you bolt the bell housing to the block, your converter must be free to turn easily. Draw the converter to the flex plate and install your bolt and tighten it. Then do the next 5 bolts.

Thanks bud. Any other secrets you wish to share? Also, just a thought. My flexplate is the stock one, has 150k miles on it... Should I be replacing it, upgrading it, worries about reusing it, things like that?
