I have a 1987 16v 1.8l, and i need a new tranny from the yard, i found a few on 8v's but all the 16v's were Auto. here are the tranny codes i found:
AUG
ACD
DF
ACN
which would be a good mate for a built 16v? cams, etc.
thanks guys.

Re: (Satur9)

well it looks like the ACD has all the same gears, except 5th is a bit taller, which i would like (.912 vs .894). Are there any issues using the 8v trans (ACD) on my 16v?
also is .894 a noticeable difference from .912?

I'd go with the AUG, apparently you can do 60 mph in second gear. Owned one too never gave me a problem.

do you think it would kill how fun the car is to drive though?

I don't know how accurate that info is... In fifth gear, my car is at 3000 rpms at 60. I can't imagine what would happen if I dropped it into second at 60.... Pretty sure AUGs have short gears.

You can always swap the flanges from the old tranny, I had to do that on my 9A http://****************.com/smile/emthup.gif
There is a section on BrokeVW's site about the different type of reverse switches..

Make sure you get one with the same axle flange size, and reverse light switch. Some use small switches that look like a oil pressure sender (I think) and others use a big black L shaped switch (like my ACH).

Re: Help choosing a transmission from the yard (bobloadmire)

AUG (late base model close ratio) and 9A/ACD (early AGLI/GTI close ratio) and AGB/2Y (16v close ratio) are all the same except that the AUG has a slightly shorter 2nd (1.94 vs. 2.12 in the others) and the 16v trannys have a shorter 5th (.91 vs. 89 in the others). I like my 2.12 second and I can sure as hell wind it up to 60mph in 2nd gear (around 5k) with plenty breathing room left.
ACN is a more economy geared trans used in the early base models (same ratios were used for 85-89 on different codes). This would have 90mm flanges too.
The differences between the different codes with the same gear ratios would be the reverse light switch (on post-88 cars it's just two pins, on pre-88 cars it's 5 pins with a signal for 5th gear for the upshift indicator)m, and the flange size. (there are other differences but this is the one of main concern to most Mk2 owners) both are can be worked around (flange swap, wiring in the different connector).
I would say look into the 9A or ACD. I know the 9A has the big reverse, the ACD might have the small one. Their ratios are identical to yours except for the slightly more economic 5th 9that's an overstatement as it's still way off from economy
). Look into the ACN if you want an easier to drive car with good economy. I was thinking of popping one of these on my 16v since the power band is decently wide to still be a quick car but it would also be very economic. There really iosn't anything wrong with the AUG but when you have the ACD/9A available with the tighter 2nd (which is really fun) go for it.
All of these transes would require a new clutch disc. 16v trans has a bigger input shaft and if you put an 8v trans on a 16v clutch disc the disc will just spin over the splines.

i just remember being able to do 90mph at like 3500 rpms. it was awesome

Yup
I have a 9A with a .75 5th swap (final is the same). I can do [email protected], [email protected] I like it but I am going to go with a 2Y and a .80 5th. The jump from 4th (1.13) to 5th that I have now is huuuge.

FV-QR

yeah i used to have a problem coming into the mountains on route 80 in connecticut. pretty steep grades that kinda flow up and down for 50 miles or so.
i'd bog the car out in 5th at 70mph because of the lack of power from the 1.8
so i'd end up down shifting into 4th at 70 and revving the **** out of the engine. thats the only time it was annoying.

Re: FV-QR (sin bar)

oh man, you guys gave me way too much to think about. I still can't decide. I like the sound of a tighter 2nd gear, but the taller 5th sounds good as well since i commute between Washington and California of a regular basis. But i also AutoX on the side too.

Re: FV-QR (VDub2625)

alright cool. yeah the first clutch lasted 20 years, this time 3. i think there was an oil leak that made it slip.
oh yeah, besides visual inspection, is there any way to get a rough idea of the condition of the transmission condition out at the yard or do i have to just pray its still good?
