I have heard that there was a T2 Bus that came stock with a full automatic transaxle. If it does exist, would it be possible to put one of these into a Bug or Ghia? I know off roaders like the Bus trannys because they are more durable. I have often thought it would be nice to have a fully automatic tranny in my Ghia. Any thoughts?  Huh

Hi! Mando headbang Smiley ,
Yup,there was a fully automatic trans for the type II,but of a completely different configuration than you might think:








from
http://www.cwgsy.net/private/ramva/fiche/ft2.htm
The very reason Type II manual Wink trannies are preferred for offroading is for their stout/solid/simple build Cool ,the A/T's were on the complicated/delicate side meant mainly to appeal to the lazy Amelican Cheesy

Well I found where I heard about the auto trans. It is in the Haynes manual and it turns out that they did manufacture a fully automatic transaxle for the 72' - 79' Type II Transporter. From what I can see in the book it looks like it might be possible with a little custom fabrication to fit one into a Ghia. Has anybody tried this?

Stick with it  Grin. These toys were designed for easy maintenance and repair by the owner (mandated by Hitler believe it or not!). They really are pretty easy to work on once you get into them. The first thing to remember is "don't over complicate anything". The simple way is usually the right way!

Yeah, I found it about the same time you were posting your reply. It is a different setup to be sure but it still looks like it might be possible. I was just hoping to find someone that had attempted it. My Ghia is a 71' with a 1915cc motor w/dual ICT 34's. I'm guessing about 90 to 100hp. That shouldn't be too much for the auto trans to handle especially with the lower weight of the Ghia. I don't hotrod it around town much (no hole shots). I like highway cruising with a little high speed backroad fun. I need to find one and do some measuring and see if it is actually feasable. Thanks for the tech diagrams, they will come in handy for selecting which model will work the best.

Not really concerned with gas mileage at this point, just researching the possibility.  Thanks for the info. Grin

Late Ghias are actually relatively heavy compared to the space they take up Sad :

~700lbs,~180hp,~2100cc,~ Dontknow 28-29MPG even when I kept it floored offroad Tongue Cheesy

I'm just gonna keep throwin' stuff out there for you to consider Wink Smiley .

Thanks Buggyman  Smiley I appreciate the info. I found lots of different weights out there. My owners manual for the Ghia lists the unladen wt. at 1918 lbs. I had a 74' Toaster (thats what it looked like anyway) and I believe curb wt. could easily be in the 3000 to 3800 lb range. A Bug weighs in at roughly 2500 lbs. This being the case, the auto tranny should shift quicker and of course be able to handle the weight much easier.  The final drive ratio on the type 003 automatic is 1:4.36 with high gear being direct 1:1. It's a little low for highway cruising but I might be able to find a higher ratio R&P. Once the torque converter locks up, it is a 1:1 transfer of rpms. So all in all gearing would be only slightly lower than a stock type 1 manual trans. With my higher reving motor performance should be acceptable. Gas mileage should still be over 20 mpg which would be tolerable for me. It is really starting to sound like a viable project. Physical size is going to be the biggest obstacle. Transmission mounts can always be fabricated to taste. Flex plates can be modified to bolt up wherever needed. I grant you it would be a large undertaking but not impossible by any means. Keep throwing stuff at me, more info is always good!  Grin

Dayo Mando Smiley .
Ya,anything are possible Cheesy ,so to that end I've been surfin' around a little Wink ,definately not in the mainstream!
Multiple variations of this search:

Here's a couple of samples of what type of mount fabrication you're gonna have to go through:

Not A/T's but you get the idear Cheesy .
Then I ran across this
"Lee, (Ol'fogasaurus), is an excellent resource for this, and several other things.
I'd suggest, however, that you post this in the off road forum."
&
"Yup, there's a couple of guys using vanagon auto's over there. Chillinintheoc and CentralWabaja are who you want to look-up." Cool

Sooooo here's their offroad forum:
http://www.shoptalkforums.com/viewforum.php?f=28  Wink
Considering that this type of differential is pretty beefy & that you're gonna be running it mostly on the street just a little taller profile rear tires should solve the freeway flyer end of it Wink Cool .
http://www.gowesty.com/ has a couple of articles on how to beef up the A/T portion of the transaxle Wink .
