i have had my new transmission in for a little while now and have started playing around with it a bit. i have noticed that when i really get on it the rpms will go up to redline really quick and stay there, when it shifts gears the rpms only drop about 100rpm. i believe the converter i have is a 15 blade that has a slightly lower stall than stock. if i use my lockup switch it takes about 3/4 of a second off my 0-60 time. im just wondering if that is normal?
thanks
