Rich, is that paint or is your case broken? Hard to tell from the picture.

Okay, the sprag in the converter is what the stator shaft is locked to. So the shock of the stator shaft breaking is applied to the converter, and as such, the sprag. Is it broken now? Maybe. Is it possible that it may break later because of that? Yes.


To me, the best solution for this problem is to have a race pump built, with a TH stator as opposed to the metric stator, and upgrade the input shaft at the same time, to the larger TH spline. That gets you a better stator and a better input shaft, which will be less likely to fail this way later. It also allows you to use a TH style converter. Yes, it is more expensive. But broken parts cost money, and usually a race.

Even if the converter doesn't get damaged, it will be full of debris. Needs to come apart either way.

Yea, my thoughts as well. 7 passes on the converter, oh well.

Alan, you make a good point. I'm gonna give a lot of thought to it.

Good question...I had not noticed that. I'll let Arnett look at that when I hand if off. ;)

The metric input shaft is rarely an issue. If anything, it's the connection of the shaft to the forward drum that fails.

There are pumps that have an upgraded metric stator support installed to solve this problem. Like a 200-4R, a stator upgrade goes a long way to making a durable long-life pump.

I'm late with a reply, but I broke a stator support one year and I could hold the throttle to the floor with out the 2step and the engine would only go to 2000. I thought the engine was broken. No tq mutiplication to the rear wheels at all. Also when my stator support broke it trashed the converter, and I ended up throwing it in the garbage. Trans and converter in one shot.

I would never run a metric without a turbo input and a billet stator support. The whole pump assmembly can be bought from Leo at Remac ready to install. Then you have interchangeable converters between the backup and the front line trans.
