How to replace the transmission oil
« on: 02 July 2019, 11:29 »
Hi, (tx for accepting me to this forum, thats my first post  ;))
I was wondering how to replace my 1971 auto stick transmission oil (which I don't think was ever replaced)
I looked for the drain plug but couldn't locate any.  :-\
Any tips and tricks please?
TX,
Eran

If yours is like mine, there should be a square pan underneath the transmission. You can buy a new gasket here https://www.evwparts.com/vwparts/AutostickTrans/001301139A.html

Fill plug should be on the left, part way up.

I suspected that myself I have this square pan with few small bolts but couldn't tell  ::).
beside that seal anything else I might require? is there a filter to replace?
I bought 3L of Castrol classic gear oil sae 90.
Is that a recommended one?

Yep, SAE 90 is the general, all weather gear oil. Here's a link to your year's manual for the transmission oil on TheSamba: https://www.thesamba.com/vw/archives/manuals/71bug/page57.jpg 

Page 67 has the fluid capacities, but just like a lot of transmissions, gear boxes, and differentials (when level of course), once it dribbles out the fill hole, it's full.

No filter to worry about. If it's never been changed just be sure to enjoy the aroma. It's delightful.

Earlier autosticks had a drain plug on the front bottom of the transmission, along with the larger square pan and gasket. Somehwere along the way VW redesigned the case to not have the drain plug and simply remove the drain pan to drain the fluid out.
Be sure you replace the pan (and gasket) before refilling the oil!  ;D Also, that fill plug is a nightmare to get at due to it being partially blocked by the frame fork (at least on mine.) It's a 17mm SOCKET head if you haven't already noticed, so you have to use a 17mm allen wrench or similar to remove it. Get ready to fill up the swear jar

Just be sure to fill with the correct amount, as it slowly goes around the gears etc, sometimes it seems to be full, but isn't really...  I'm lucky mine has a drain plug...  To fill Mine I use a litre bottle [castrol] which has a long nozzle I can put in the filler hole and squeeze the bottle to get the oil in... The OIL Has to Be HYPOID SAE 30    Make Sure Your oil is HYPOID OIL... VERY IMPORTANT.... You will never forget the smell....

Tx you all for the information, I was in the dark for too long on that one, and I guess I have a lot to learn about this unique transmission and I realized its a rare car in Israel.
I will update with my progress.
TX  ;)
