Don't quote me, but I believe that the 5 ribs have the mounting ears on the bell housing. Then again you can always change the bell housing. right?

Yes it should have the top mounting bosses on the bell housing for Buses in the USA.
When the engine changed from a type I to a type IV in the USA they added the extra mounting place to carry the heavier weight of the engine.
Should not be a problem with any interference with the body that I can remember.

One differences you will have is a 1971 and later 002 uses a throw out bearing that uses a guide sleeve and no donut on pressure plate. You could always switch out the bell housing and use the old style throw out bearing that on the early trans and keep the pressure plate you have.


I was wondering if the R&P difference would between the 3 rib and 5 rib would be ok for the stock 1600 in my '71 Bus? Not exactly a freeway flyer, but, maybe an in-betweener for a lower rpm while cruising at 60-65. At 60, my rpm's are right under 4k.
A lot of people get the freeway flyer and a lot of people say the rpm's are too low for cooling 1600. I was wanting an in-betweener, if there is one. Would a 5 rib fit the bill?

Canes,
I would use the Weddle Industries gear ratio chart to figure out what you need/want to do.
The height of the rear tires can make a difference too.
How much does your Bus weigh also has to be taken into consideration. Is it only you driving it, or carry other people or cargo?
When you say stock 1600cc engine, is it stock carburation, stock exhaust, and other stock parts?

Where is the chart showing bus and vanagon automatic gear ratios? I'm trying to find which one had the lowest gearing.

So. I just went through all 26 pages and am now dumber than I was. No offense. I mean I don't understand a lot.
I have a baja with 1835(someday will have a larger stroked motor). I would like to keep a type 1 trans. (Don't want the expense and fabbing need to install a bus one.
That being said, what would be the best type one to have or have built? Definitely want a LSD. I do a lot of sand dunes with 13.5x15 paddles and am running 31.5 baja claws in the street and mud. As it is now I'm about 85% 1st and 15% 2nd in the sand. Never third. Streets not too bad. I can do 55-65 somewhat steady but it will slow down from 65-70 to 55-60 in forth if there is good headwind or really mild hills.
Also not sure if there is a stronger reverse or something that could be done to make it stronger. Seems like if you ever have any torque or higher wheel spin that they like to give out.
Is there an easy math formula for calculating Mph at RPM? With R&P and gear ratios.
Also what does "close ratio" gearing do for you? And "Welded gears"
Any help or ideas would be great. I have (5) bad type one trannys laying around from several different years. Also is there a "holy grail" type one transaxle year/code that is best to use?? Thanks again. Just trying to understand and learn. Thanks.

You're cutting into that range where a bus 002 would really benefit you.

Here is a list of stock gearing: http://www.ratwell.com/mirror/sandlizrd.baja.com/gears.htm

Here is a calculator for tire size vs transmission gearing: http://johnmaherracing.com/calculators/gear-ratio-calculator/

From what I get, a SSC is the good T1 transmission. Slap the proper gearing in and you'd be set man.

I can SURE use SOME help & some SOUND advice:

AKA Mel Here, I live in Costa Rica Central America, I just got done building my first Dream “69 Dune Buggy” & it has been an intense ride now approaching 5 months, we’re about 98% done, but my shifter is not tight at all, too much play if you know what I mean, and on top of that, its not dialed in properly, my Mechanic who can drive shift efficiently has some trouble with it as well ( he did a great job on the engine ), but he’s not a transmission specialist, even do I put a ton of cash into it, I’m having some doubts at this stage if I can learn how to drive stick efficiently at 52 years old, it is a bit stressful, I was told the easy fix would be to find a VW Bus Automatic Transmission and call it a day, I have well over 15K into it now, so 1-2 More K won’t make much of a difference. Can someone help me, I need sound advice from an expert. you can also contact me on my Skype, ID = Carmine-Puleo, I’m the one registered in North Miami Beach.

Pictures Link below

Thank you all in advance.

Sloppy shifter the 1st place to look would be to take out the 2 bolts that hold the shifter to the tunnel and that exposes the shift shaft. Reach in and see if that wiggles. It should be firmly held in place, able to slide forward and back or rotate.

If it's sloppy, there is a plastic bushing right behind the opening that is the culprit. Replacing that $3 part requires taking off the plate at the back of the tunnel and disconnecting the shift shaft from the coupling joint. There is another plate in the front hiding behind the beam. Take that out and slide the shift shaft out, then slip the new bushing in. There is a ring on the bushing like a key ring. Make sure that's in the groove in the bushing, put a little WD40 or something like it on the shaft and slip it back in.

The other suspect is the u-joint-like coupling at the back end of the shift shaft. 2 screws to replace that and also just a few bucks.

Anyone use a 6 Rib Tranny on a Split Window Bus?
The 6 Rib tranny pictured below came from a '76-'79 bay and I believe its a 091 with a 4.56 R&P Ratio

I would like to use it in my '67 Split window bus

I have not installed one in a Bus, but have installed them in buggies using a Bug chassis.
It should fit, but will require making mounts and maybe some cutting on the frame horns for clearance. From bell housing to nose cone it is approx. 1in longer then your original trans. So it needs to pushed as far forward as possible.
Also the trans axle is a hypoid design, to have equal length CV axles you need to offset the trans to one side a little. I don't have the measurement in front of me now.

Is it possible to run a bus auto trans in reverse rotation? If not, how would you make a sequential shifter on a bus trans?
This is for a Swedish style trike build.

I bought parts for my ecotec and 002 conversion 2 years ago and now im not sure on the proper pressure plate set up and I might have the wrong throw out bearing. I have a 002 with no provisions for a bearing tube not knowing the year of my trans dos that mean i have a pre 71 setup. i got the parts from pacific customs and they say i need 71 and later style.

Looking at the picture in your build thread, you have a 1970 and earlier bell housing on your 002 transaxle. There a couple of ways of making things work.
You can use a early style pressure plate that has the donut on it.
All Kennedy pressure plates have one, you remove if you are using it on a later trans that has a guide sleeve.
Another way is to use adapter guide sleeve (Weddle sells them) that fit where main shaft seal is. It uses a smaller OD main shaft seal inside the sleeve. You also have to change the TO bearing cross shaft to a later style for the later style TO bearing.
Still another way is to change out to a 1971 to 1975 bell housing that has the guide sleeve.
My own personal preference with other than a air cooled engine is to use a 228mm flywheel and clutch parts. 228mm is very close to 9in diameter, and the 200mm is little less than 8in. More surface area and the stock 228mm pressure plate is close to the same pressure as a stage 1 pressure plate.
To use this set up does require a 1976 and later bell housing and the starter needs to changed too.
It is the setup I using with my 2.5L Subaru powered buggy.
