Yes....the earlier units....wait until I can get home to confirm whether its early or late......have a five bolt mounting ring around the stub axle on the differential housing on each wide that holds the seal assembly.
In those early models....the stub axle is just like a beetle/type 1. It has the spacer tube between the two side shafts within the eifferential... with the spider gear cross shaft going through it. The outer CV flanges are held on with splines and snap ring.
On the later model.....single side seals...one piece flange and stub axle that fit in from the outside ...and are held in with a through bolt through the stub axle. Ray |

You wont have to remove the engine or transmission, but you will need to drain the fluid and drop the pan. Make sure the trike is jacked up high enough so you can work under it. Take a look at the photo and the three arrows.
You should be able to see this after the pan is off. The two red arrows attach the internal mechanism to the external lever. Make sure that the spring is in its cup, and the hook is grabbing on to its nub. If the spring isn't in the cup, the hook will not stay latched.
The white arrow points to a little shaft that extends out and engages the manual valve on the valve body assembly. Make sure that the shaft is in the groove of the manual valve.
To make any corrections you may have to drop the valve body some. Make sure that you only loosen screws that holds the valve body to the case. You don't want to split the valve body open, or you will be chasing balls and springs. You shouldn't have to remove the valve body completely, just loosen the screws enough where it can drop down enough to make your repairs.
Good luck and keep us posted.

I picked up my master kit from Cobra Transmissions, Kit was made my Attomatic (division of Raybestos) with Attomatic "High Energy" green semi-metallic frictions and new steels.
I was going to have everything redone in carbon metallic by Alabama Transmission Bands, but they recommended I keep the the green stuff for a DD/street/strip combo, they said CM frictions can cause issues (racing only suggested) but CM worked fine for the bands.
The bands are carbon metallic, resurfaced by Alabama Transmission Bands.
They don't usually "do" (and are not set up for) direct sales, but for oddball transmissions they will work direct, due to their usual 50 pc min order, it isn't worth it for their regulars to do oddballs like a 003.
I ended up sending them the frictions, they sent the Raybestos frictions back untouched after discussion, and provided the 2 bands w/carbon metallic lining, price on the bands was excellent, they had them on the shelf, and just redid the linings. Once I had the parts and the price I sent them a check, great folks to work with.
I have an earlier trans with the 5 bolt side plates/stub retainers, I cut the deep retainer flanges down and they are now on with countersunk screws. I also welded T4 flanges on,the stubs, and extended both drive stubs to mate up with a Vanagon right axles, and a 914 left axle, with clearanced T4 CVs on the L side. (944T rear arms, early/narrow(er) under a square, with custom coil overs I built from fox "truck" 2.0s for a Chevy van)
Trans is on centerline, and CVs have proper clearances.

Hi
Thankyou for the awesome post, it has given me confidence to do my own repair prior to paying $3k for a rebuild.
My kombi won't go into reverse or 3rd gear, from online reading I think its the actuator and it can be replaced without a rebuild. I am unable to find any diagrams showing its location or how to remove and repair it. I already have a rebuild kit which came with the kombi, so probably have the parts required
Any info from anyone would be appreciated.
During this process I have found a site which others might find useful, its a outline of how the gearbox works, but is in german.
http://www.volkspage.net/technik/ssp/ssp/SSP_8.PDF
the site has quite a lot of useful VW training information:

That is the exact problem I was facing when I rebuilt the transmission and wrote the how to. This is a direct quote from the Bentley: "(Problem) - No drive in 3rd gear or reverse. (Probable Cause) - Direct and Reverse clutch defective. (Remedy) Repair clutch.
Your first step is to drain the ATF fluid, preferably in a clear or white container. If the fluid is not a nice pretty pink color, but has discoloration like in the photo below, your clutch is bad. The outside of the trans and the pan were perfectly clean, before the tear down, the discoloration is from the burned fiber plate material mixing with the ATF fluid.

Hey Multi69 I need your help. I had my tranny rebuilt and as you can see it is now installed in my car. I’m having a little trouble getting the Bowden cable in the correct place? I’ve read the Bentley but can’t get the parking lock to engage on the tranny as per the Bentley. FYI the shift lever is in Park and the Manual Valve Lever is all the way to the rear of the car. Any suggestions? Thanks |

Gheezer, sorry for the late reply, work has been a mad house. Because of the differential action, when you spin a rear wheel in one direction, the other spins in the opposite direction. To get the parking paul to lock the transmission, you have to spin both wheels in the same direction. So grab a buddy, spin both wheels in the same direction and it will engage. If it doesn't, the rebuilder did something wrong.
Good luck.

It is an 003 but has different/lower gearing than the Type 3 model.

Would the 003 master rebuild kit work the 76 bus tranny? I'm in a pickle and need to figure out my next move |

I imagine the 003 kit would work in all of them? The torque converters had different stall speeds too as I recall.

So I taking a stab in the dark...
So if I change the gearing and torque converter to whatever the type 3 specs are and use the master rebuild kit, I can run a auto bus tranny in a fastback? Or I can rebuild the bus tranny with an 003 master rebuild kit and throw it in a late bay |
