Hi,

On my Vanagon 1988, i cannot shift in third and fourth gear. I really don't know what's the problem is. ANY IDEAS. Thank you for your help :cry:

Good chance your 3-4 slider hub is broken. Only way to fix it is a transmission rebuild.

I would still go through proper diagnosis steps.

This explains that particular failure:

By all means rule out the simple stuff first including the linkage which contains some wear parts.

I very recently got a rebuild from AZ Transaxle. Bill was great to work with and gave me good guidance in selection of options. Also bailed me out when UPS lost the transaxle I was shipping to him.

My transmission was shifting fine and found the broken 3/4 hub while tackling something else in the transaxle. Its about as far into the transaxle as you can get. Hope its something simple and external.

Change your transaxle oil.
If 3rd/4th slider is broken there could be some metal chunks on the drain plug magnet.
Post a pic of the magnet's fuzzy hairdo.

And if no chunks, well at least you maintained your valuable transaxle.
Most people 'maintain it' after there are problems, or noise.
There is no oil available that can repair the damage done by non-maintenance.

Transaxle is out of sight, out of mind for most people, thus suffers very poor maintenance.

Sure, it could be the 3-4 slider, but it could also be the shift linkage, play in the shift ball, worn out shifter cup, etc, etc... Start simple first. Try shifting at the trans. Have someone else shift between gears while you watch the lever at the trans to see for play, etc.

Hi,

Effectively, it was the 3-4 slider hub broken in two pieces.

Thank you for your help.
