this gear or any of the other ones this person sells work in my 84 diesel right? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33733&item=2476923131&rd=1&ssPageName=WD1V
I would just have to go out and buy the gasket, tool and c-clip and have fun one saturday right?
Most of my driving in 5th gear is on the highway after I have accelerated to 70mph then I cruise at about 75mph so a longer 5th is much needed for me as 80mph would be a more optimum speed for me to stay with traffic.
84 TD in question

Somebody back me up on this one but didn`t Autotech have such a kit at one time???? :?
-
yes $240
I am not paying a 1/3 for a 5th gear of what I paid for the car....

FWIW, I put a longer fifth gear in one of my rabbit GTI's. The fifth in my 2H was practically unbearable for highway driving.
We used a .75 gear out of another gearbox (longer ratio) and with a friend's help, we got it done in less than an evening. Not very hard, but you do need the tool (I believe it's the same as the triple-square head bolt socket on most VW's). I remember my friend used a torch to add heat at some point to help the process along.
The new fifth is great! Vast improvement for longer trips.

Your 1984 TD should have a 0.711:1 fifth gear set in it already. That car should have either an FN or a 7A transmission. Either of those already have the tallest 5th gear available (0.711:1).
Check the code on the bell housing of your transmission to see what you have now. There's a 2 or 3 character code and a 5 digit number. If you post the whole code, I can tell you which 5th gear set you have now.
That's not a really good price on that gear set either. I'd get you a used set for at least $30 cheaper than that (and I'd still make a few dollars on it at $60 for the set).
And you'll need a new 5th gear housing gasket, a new 5th gear retaining bolt, a new 5th gear shift fork locking plate and a new 5th gear circlip for the pinion shaft. The bolt is expen$ive (like $45-$55 last time I checked). The bolt is a highly stressed fastener and is a "use once" bolt. The shoulder of the bolt can fail if you re-use it, and with the helical cut gears, if the bolt fails, the gear shoots out the end of the transmission.
You can get by without the special tool for the shift fork, just use vice grips on the outside of the shift fork tube (very carefully).

I've done the 5th gear swap 3 times now, and can do it in 3-4 hrs. Instead of the special tool, I ground the end of an 11 mm socket so it had 2 tabs that fit the selector tube.

The Ebay aution he was showing was for the R&P, Final Drive...not the 5th gear. He does have the lowest 5th possible, but he may not have the 3.67 final drive; probably has the 3.89 found in the FN/7A. So by using this Final Drive off of Ebay, he'd be even taller.
I'd like to find those 3.42 (Dodge Omni) or 3.29 (some 4S models?) R&P and install that with the .71 5th (FN/7A. That would be tall. Would be the closest 020 folks could come to the 3.156 X .681 combo that the 02A folks are doing.

The unfortunate thing about the 4 speed final drive is that it can only be used in a 4 speed. The pinion is an integral part of the transmission countershaft. On a 4 speed the countershaft does not have the extension to mount 5th gear.

Why not just go to an 02A and avoid the whole 020 shift linkage issue altogether? ;)
Anyway... make sure you guys have the power to back it up... my 3.94 R&P and (depending on who you ask... Bentley says .745, Scirocco.org says .89, and my owner's manual and my ear-tach agree with .89) 5th are too tall for my 52 horses, when I need to climb a hill at speed or pass. :?
Assuming a .89 5th, I could use like a .85 6th, and a .91 5th... I'd still have to downshift to pass, but it'd be lower RPMs than a 1.03...

cause teh 020a shifts like crap and unless you use the cable throw out from older eurovan you need hydr clutch, and shift cables.. etc etc.. you can drive 020 with out using the clutch and its is nice..thgey aren't as strong ..but as long as you don't dump teh cluthc at a start and slowy apply the power you should be good. a 2.0L gasser with a cam would easyily pull my 367 and .71 gear combo so abuilt 1.6L TD or a tdi m would really workwell im swapping in a 367 r& p into my 7a td box with a quaife in it ..i hope that works well

Easy to cure the sloppy 020 shift linkage:

I'm just getting done installing a 3.67 ring/pinion gear set in my FN transaxle, so coupled with a 0.71:1 5th gear, should drop the highway revs to about 2500 @ 65.
