offroadfrnce asked the same question and I checked the exact size and pitch and posted it. I have tried to find the thread, but cant.

It was during his time when he was making a trans dip stick kit to sell on ebay.

Good luck

 

it must have been a PM where he asked me, here is his response after thinking my measurement was wrong:

"There has been a minor setback, firstly Abran Abeyta was spot on [img]images/smilies/bowdown.gif[/img], the D2 autobox fill/level thread is defo M16 and not M17 that I've been working on. Secondly, the freight company I use have deferred for another week so the clips and brackets won't arrive for another couple of weeks. "

 

Ahhhhh... M16x1.5 ... same as the TD5 oil drain plug. cheers Abran!
