torque converter solution

I see that you live in Montreal. Your best bet, and the most knowledgeable company I know of to contact in your area would be SMR transmissions in Brantford Ont. Their toll free number is 1-888-846-6603. Pat Storey is the owner and a good guy to deal with. When I worked in the industry, I sold him lots of High Performance parts and had the chance to meet with him personally at a major car show in Toronto. Very nice guy and very knowledgeable. Just tell them what you need and they'll fix you up I'm sure.
