Hi guys I was wondering if anybody can help with this problem I keep having on the track. What happens is when I drive the car in 2nd no issues at all. If I collide with something the car drives like it's in first. Over revving and wheel spinning if I pull the car up and leave it it will select 2nd and be fine. We have changed the welded diff and box still does it. Changed the short shaft still the same. It does it at different tracks. Also when o started from a clutch start not a rolling start it did it as well. The clutch is a stage 2 Kevlar option so I haven't ruled it out but wasn't top of my list.
cheers
