Hi All,

My XK8, after putting in a used transmission shifts kind of wonky-

In sport it almost feels normal

In "D" it shifts (pretty) smooth, sometimes long.

When accelerating, I would expect a downshift at 1/4-1/2 throttle but it stays in the same gear and is slow... Is there anything I can do to reset it so that it downshifts earlier and more often?

Thanks!

D
