Glitch with auto
Hey guys, i have a little problem that someone here may know how to fix.
I have a BA XR6 turbo, with a modified auto. The auto is rock solid and coping well with 280rwkw's.
Tonight at Calder i tried a new way of driving down the 1/4 mile, this resulted in my quickest time aswell as discovering a slight problem. I launch in performance mode and let the car self shift 1-2, i then shift manually 2-3 at about 5600-5700rpm. So far its all good. Out of 5 runs tonight all except one had the following problem, after being in 3rd for a little while the car would then change into 4th at about 5000rpm (not sure on exact rpm). This has a real bad effect on my times.
I was hoping someone might have some idea why this is happening and ways to rectify it. Its possible that its a cpu glitch or something. As it only happens over 160kmph its a bit hard to show the service department or other people. I'll be asking my service manager, Amberly auto and also my transmission place (Kewish Automotive), what they think at the first oportunity. I was hoping you guys might have ideas in the mean time.
Any ideas would be great.
