I've sent three emails to Kondolay over the last two months but I haven't gotten a reply. I live 40 miles west of Philadelphia Pa and I'm trying to locate the closest shop qualified to do a DTT rebuild on my trans. A friend of mine drove to Mass. but I don't have that much spare time. I originally heard of a guy near Pittsburgh Pa that had a big reputation. Would also consider a ATS trans, don't know if they handle the 500hp range as well as the DTT does. Would appreciate any replies. Thanks for your time Larry.
