4r70w Rebuild Question

[chirpinsecond]

I wanted to get my 4r70w rebuilt locally if possible. I live in Southern Maryland and was looking for a rebuilder that has had some proven success building a "tough" 4r70w. The trans needs to hold up to some power and I have not found a reasonably local shop to rebuild it for me. I will ship it out if needed, but wanted to stay local if possible. I am about 45 minutes south of DC.

If I can not find one local, who would be the best company to send it away to?

Thanks
