914World.com _ 914World Garage _ Vanagon transmission?

Posted by: Sean_S Oct 30 2004, 02:18 PM

Hi all,

Here comes my endless stream of mostly rehashed questions.

I think I'll start with this one...

Aren't T4 engines in both 914's and VW busses, and if so what are the differences between the 914 tran's and the 3 or 6 rib bus/vanagon trannys?

Just wondering because I thought some of these would interchange and it seems like a bus tranny would be beefier.

Thoughts?

The bus tranny might be beefier, but you would have to flip the ring and pinion on it. On a bus the engine is in the back, the 914 it is in the front. I have heard you can use an Audi 5000 tranny but I dont know of anyone that has.

Ugh....

5 speed replaced with 4 speed......

4000 rpm is 70mph.......

On top of that, there is a fatal design flaw where someone impersonated an engineer and put 3 rectangular notches into the gears. Seems there is no radius at the corners of the notches so the stresses are close to infinite at the corners.

This shows up as a gear going away. When you go in there, you find 1/3 of the missing gear laying in the bottom of the tranny and usually one or two of the other notches having a crack.

Ask me how I know..

I never designed crap like that! Musta been the same guy that put rivets in the GTI tranny...... another accident waiting to happen.....

Love my Vanagon tho....
