My transmission mostly shifts fine but that 1 -> 2 nibble is there most of the time, weirdly, particularly when turning left.??? Makes me wonder if the transmission torques out of line with the shifter a bit during a left turn.

Deysha can you confirm whether use of XL-18 is now thought to be harmful or not?

Anyone know?
