OK, so I pumped out the ATF and replaced with SAE 15W/40. No change to the result: reverse engages instantly but forward is slow, in fact it won't engage unless I dethrottle, wait, listen for the engagement, then throttle ahead. I'm going with your advice and that of Ceejay to redrain and refill to improve the quality. Can't get my head around why reverse would work but forward not with the same oil.
By the way PaulRainbow, is there a difference between diesel SAE 15W/40 and other types of SAE 15W/40?
