I am about to have a converter built for my car from Edge Racing Converters. However, they tell me in the 21 years that they have been building converters, a "handful" of times there were 2 different auto trannies. He said over 95% have been the same..and but a few have been different. I trust Edge, since I have used them in the past with great success. So which tranny is likely in my 1994, and is there an ID plate, or serial number on the transmission itself I can confirm? Where do I look for this info? Any help is appreciated.
