Transmission shop recommendation

I just picked up a th400 that id like to have put on a tranny dyno to check the pressures and do the converter feed restrictor mod.

The mod is to prevent the converter pressure from pushing the converter forward into the engine taking out the thrust bearing.

Thanks

Competition transmission on Erie might be able to help
