I thought the XL-18 additive was now being discouraged because it might have long term harmful effects on the synchros. I would not mind trying it, the $23 is worth the experiment, but if it negatively affects the longevity of the synchros, then no way.

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?
