I own a 2001 VRX and when I go from 3rd to 4th either via auto or by manual shifting it goes into 4th, back to 3rd then back into 4th. Anyone else had this issue? Yet to do a ecu reset but wondering what else it could be?

Mine sounds a bit similar, from second to third when it gets hot aka at a trackday, theres a jerk from second to third like it revs but doesnt go into gear. just trans getting hot but in normal driving no problems.

Anyone got a answer of any kind for me?

What colour is your Trans Fluid? Black/Brown/ Dirty or a nice healthy Red?
