Are there any 6-speed tranny's out there that are a direct fit replacement for 1.9 IDI in a mk3?? Trying to get the rpm's down on the highway. I've considered a 5th swap but all's that's available is the 0.68 and it's a hard to find gear, as well what I've read going from 4th to 5th could be a concern.
Any thoughts on this appreciated. Thanks..

There is a tranny in europe...it is not a direct swap for a 020 but it is for a 02a.....its called the 02s and it came in 2 gear sets i believe one was long gears from a tdi and one was short for a gasser. it was a 6 speed. In order to install one into a mkIII you would either need to switch to a hydraulic clutch set-up or try and find the very rare 02a cable from a euro van. (I think) My buddy has it in his sirocco....hes running a 02a with the stock pedal cluster and master cylinder.
Either than that I dont think you will find anything.

OMG !! $4,600 !!!! How much does a reman trans from VW cost ? Can't be that high. http://www.autotech.com/quaife/index2.htm
What about shorter ring & pinion gears ? My last American diesel had a ration of 2.73 : 1 or there abouts. It gave me a highway RPM in the 1900 range. Would be nice to have this on a VW I'd think.

There WAS a company making a similar kit to add to an 020.
VL Enterprises was the name of the company, and it was the "Option-6" package.
The price looked crazy to me then (mid-late 90's) but looks good compared to the quaife option.
HOWEVER, the quaife is a full replacement gear stack for performance folks. I am pretty sure VL is no longer around.
You can also swap to a hydro trans assy, and then the world is your oyster! Just gotta mount the clutch hydraulics on the firewall, and install cable shift mech in the tunnel.
Also, do a little looking at your final drive:
My Tranny (Code: ACH, 85 TD) is a .75 5th gear with a 3.99 final drive.
If you can find a box with the 3.667 final (regular golf/jetta gl box)
you should see a noticeable drop in RPM's.
If you can combine that with a .71 or the mythical .688 5th,
(I saw a dealership selling them for like $350 for the set of 5th gears) you are really getting somewhere.
brokevw.com has the motherload of data on the 020 if you want to start seeking out your perfect box. There are a lot of unique boxes out there with favorable numbers.
I say find an 020 locally for $100 (regular GL box, 3.667 final and either a .75/.71 5th) and throw that in, and then tell me how much that helps, and then I will know if I need to do it too!
I am in the same boat... 70MPH = 3000-3100 RPM, and I am tached out by 85 MPH.
Thanks!

Yeah, maybe that was where I had read the bad stories.
I recall hearing some stuff over the years.
That was a hypothetical, I suppose, anyway.
(Yeah, there USED to be a guy making exactly what you want to buy now.... Well, no, he does not make it anymore... Well, no, when he made it it was not really that good.... No, I am pretty sure none of them even still exist....Glad I could help!!)
But I did see one for sale on the Vortex a year or 2 ago, but they were asking like 2X original retail...... I hate the Vortex. Dont even get me started on BBS wheels!
I digress.

you can probably find a 6 speed box for about $1500 in decent shape... i wouldn't bother trying to convert a 5 speed into 6...
several people have been putting 6 speed boxes into mk3's and i've even heard of them in mk2's. all you need is a custom bracket.
-
thought about a mkv tdi 6 speed gearbox? fyi the bellhousing should bolt up to any 4 cyl, unsure about the rest tho.

ACN code tranny as a pretty tall fifth from late 80s early 90s gassers

Got this box to go in the wife's car. I think it's the tallest 020 box there is.
70mph = 2885 RPM's.

i have a gasser cluster with no tach so I haven't been able to know how much revs I've been turning since I swapped tranny's

tdi final, does it fit?
-
I found these = maybe an alternative to a 6-swap. Pricey but cheaper than a swap. I think the .681 will be my choice.

those are very viable options for better mileage. its really hard to justify spending so much on a 6 speed box just for the increased mileage. one must also take into account the added performance benefit :twisted:

So will those gear sets fit an 020?

as far as i know they will.
-
just how much work is involved to make it fit?

not much... it can actually be done while in the car. just follow the online instructions. the best way to get the gears out is not with a puller, but to actually heat them up. then they will just slide right off. i seem to recall that you can actually break something inside if you use a puller... maybe the gear itself??? :shock:

If your asking about the gear sets on kermatdi and tdiparts... they are for a 02J in the a4 platform and will not fit a 020.

that gearset should fit on an 020.

That link goes to a gearset for a o2j. I guess it does say "fits 96 and newer and some older" (paraphrase)
Are you saying that some 020 and 02j's have interchangeable gears?

If you can squeeze taller tires on your car, you'll also drop your rpm...

Actually I thought of that - I'm running 195-60x14" which is a 23.2" tall tire now, I think it could easily handle a 195-65x14" which is 24" tall or maybe even a 195-70x14" which is 24.7" tall, both are the same width as the 195-60x14's. Expensive gamble though - fitment wise.
-
How fast are you cruising at? Why not use a .71 out of a lot of old diesel 020's?
I don't have a tach, but the .71 in my rabbit is actually a little too tall for my taste.
FYI, early dodge omni 4sp's were vw transmissions with a tall r&p, I think.
-
i'm installing a CTN in my mk2 jetta. it has the tallest r&p available, but the 5th gear can still go lower 8) . i'll be bolting the clutch master cyl to the firewall and then putting a rod from the clutch pedal to it with the right angle. way cheaper than doing the cable conversion, plus i kinda like hydraulic :lol:
also going cable clutch will be cool! 2100 rpm is nearly 60 mph. 8)
