I cant speak for the AOD but when I changed out my Tremec for a C4,my times got better,I ran a previous best of 12.40 with the Tremec and first pass with the C4 was a 12.21,and improved to 12.11,I have a TCI C4 with a 3800 stall 10" converter,I also thought my times would suffer going to Ao\uto but they didnt ,was a pleasant suprise,your situation may be different but I am very pleased with the auto conversion and my times have crunched up very consistently.( and before anyone says it,yes I can drive the hell out of a clutch)...LOL this is my FIRST race auto,I have been racing Jericho's for years. and Merry Christmas to everyone
