Yeah, its mostly correct. The only change i would make is its not really about 6 speed vs 5 speed, yet its about AWD vs. 2wd when it comes to length of the trans box and fitting in the space.
P.S. You cant move the engine backwards to make room for the trans, because you exceed the CV's acceptable angles. Even with Porsche CV's. |
Thank you! |

I have a vw sand rail, and recently installed the 5 speed subaru transmission using the reversed ring and pinion with a 1.8 t from a 2002 a4 .I have driven the buggy a total of probably 5 hrs. I blew the spider gears in the diff. I'm pulling the transmission out today and hoping the ring and
Pinion survived so i can sell it . I haven't found any heavy duty differential for this that aren't a positract., I run steering g brakes and need a open diff.
I do drive very hard but do know how not to abuse the transmission .I've ran the 091 transmission for 30 years and even short course raced with a atock 091 trans.
I wish I spent the money on a mendiola |

I'm in the process of modifying another Subaru 5MT to put into my 1.9AAZ powered Doka, using the 50degree SG adapter plate.
My Question:
What (#@&*$*(!! starter am I supposed to use? I've tried a few different VW starters to no avail; the mounting bolt holes don't match up. |

It's not simple because there are many ways to build a VW gearbox.
The good, the bad, and the ugly.
And none of the methods nor the gearboxes, are OEM.
I think/hope some can be better than OEM but the cost is "unreal".
We don't know yet if Subarus are stronger.
The Subaru R&P is quite a bit smaller than the Vanagon R&P.
The Subaru case is much thinner and lighter than the VW case.
Nobody is reporting mileages. |
Not a Subaru Gearbox ...... but
I built my Air-cool DK transmission in 2010 for a TDI in my 84 Tin-top. It was put in service August, 2012. It now has over 85k miles on it. I used Weddle parts (over $1,000).
27" tires, 1.13 3rd,.77 4th, 4.57 R&P (3075 RPMs=70 MPH)
And, as many of you know, I drove it to Alaska in 2014 & 16 pulling a popup camper (1200 lbs) with loads of stuff on board in the camper and inside the van. The 2016 trip had two additional adults on board and all their stuff. Total miles for those two trips was over 25k.
It has a worn spot on one tooth of the Pinion gear. It was worn before heading out on the second trip to Alaska in 2016. That's been about 15k miles back.
In my opinion, the Vanagon transmission cases are strong. I've never seen one busted. In my opinion the OE style bearings for 3rd and 4th gears are the weakest point. They are in plastic cages. Third gear idler is spinning extremely fast when the transmission is in 4th gear at 70 MPH with OE short gears. Third and 4th idlers are on the Main Shaft which is in the top of the transmission and only get sling oil for lube and cooling. If the plastic cage gives up the ghost, in a matter of seconds teeth will begin to fly off one or both gears (idler and opposing gear)
Hopefully, I'll have a new built DK by early winter. (so far, over $3,000 in )pieces parts)
Yes, it is expensive now days to rebuild a Vanagon transmission. Weddle's prices are out pacing inflation and some things are sold out. Right now, they do not have the front pinion bearing. It is an odd ball and INA no longer makes it.
Tip: Change the break-in oil in 500 miles ... change again in 1500 miles and again in 5000 miles. I used regular Dino oil for break-ins. I'm presently using Synchromesh Pennzoil.
