Converter has reached its limit

PTC, Coan, pro torque, FTI, yank. All good companies. I used Continental for all of mine as I had a friend working for them but unfortunately are now out of business. The best converter will be one built for your exact combo. If you have a company you trust just call em and have one built and you won’t regret it. The more data you give them the better it will be. Turbo cars like load so lock ups and low (relatively speaking like 4500) stall speeds are typical.
