i know its metric, just like everything else on a VW, just dont know the size.

why are you replacing the drain plug? is the head of it stripped out? that should be the only reason to replace it.

just order a drain plug for a mid 90s chevy 1500 truck (NV3550 5 spd trans) and that will work. ive used a drain plug from a 94 chevy 1500 V6/5spd in a VW trans before, without issue.

because if its npt i would replace it with any plug i want. so i dont need a stupid tool or to make up a tool. ill probably end up making a tool.

if thats the only reason, then just make the tool..

FWIW, VW is not the only company that used plugs like that on transmissions.. so the tool will be useful on other vehicles also, as was mentioned..

you can take a bolt with a 17mm head, and weld a nut on the threaded part, and you have an instant tool. or weld a handle to the bolt.

that plug is low profile so it doesnt catch on anything.. if you had a plug with a nice big head on it, something could rip it right out of the transmission..

if you work on VWs very often, the tool will be better, because most older VWs use that style of plug..

rather than just replacing the plug with something you can get a wrench on..

if you have a welder, or a buddy with a welder, then a tool is EASY to make.. took me 5 mins..

have a welder. they do make plugs that size with smaller allen heads in them which would be easier. ill just weld a nut to an old wrench and be done with it.

dont work on many vws just this one. only dodges.

i really think its npt.. its a taper thread...

smaller not such a good idea.. and honestly.. welded bolt trick never seems to work for me..

one thing to rember.. this is biggy... do not make tight tight when the tranny is warm/hot.. you will fight it big time to get it out ever again..

just visit a snap on guy.. send the ~$20 on the 17mm allen socket.. i suggest 1/2" drive.. yes ive had them that tight...

Since I used the TDI 12pt crank bolt I needed a 12pt socket. Well the 6pt socket 19mm I have wasn't being used so I took an old wheel bolt and burnt it into my socket. Now I have a 1/2" drive trans tool socket. Works real slick.

I bought a set of Allens on 1/2 inch drive for less than 10 bucks.  Works great, and less filling.

i was gonna use some thread tape and soft setting pipe dope so that it would be easier to get out next time. they probably used something different from the factory that makes it a pita
