We run this part on our own cars and it is a favourite with customers who want a simple, affordable improvement to gearchange precision without harshness. If you are feeling vagueness through the lever or noticing imprecise shifts, a worn front mount bush is a common culprit. This Powerflex solution tightens everything up while keeping NVH in check.
