I recently made a surprising discovery. Direct Scan data indicated my 87 GN was going 96 mph (in 3rd gear) and the engine was turning 5225 rpm. If I did the calculations correctly (3.42 rear gears, 1:1 3rd gear ratio, 26 in. tires), at 100% torque converter efficiecy my speed should have been 118 mph. I expected to see a loss of approximately 7-8% instead of approximately 18%. Am doing something wrong or is my converter very ineffecient? BTW, my transmission is newly rebuilt.
