Author Topic: AWY trans blew - what to replace with? (Read 13836 times)

rackley · « **on:** April 21, 2005, 07:00:56 pm »

Well I engaged 2nd gear today and my trans stopped the car dead from 30mph. All I have is a VERY rattly and clunky 3rd gear. So it's time to get rid of this highway-horrible AWY.

I see from earlier threads that the AGS is a good choice. But the only problem with that is there seem to be very few (if any) junkyards that have them (searching on www.car-part.com).

What other transmissions will fit? I can see from this page http://www.scirocco.org/gears/ that a bunch of the 8v transmissions have similar gearings...but will they actually fit my 91 Jetta...mate up to the engine, drive shafts, and shifting linkages? Will anything with a 90mm axle flange bolt up?

Thanks,
Ray

That's kind of strange your car actually has a close ratio trans in it. I can see how it would be terrible on the freeway with the diesel. Do you know if you car car actually has 90mm cv's? Most of the A2's had 100mm cv's. The obvious difference between transmissions are the reverse light switch, the differential type, and input shaft size. Early transmissions like the FF are supposedly missing a mounting point which is required to bolt them into an A2, but starting with the 4K they changed the casting. So, a 4K, 9A, ACH, etc should fit. Stay away from 16v transmissions unless you want to switch to the 16v clutch disk as the input shaft on the trans is bigger. All of the 020 (75-99.5 4cyl exc new beetle, Passat 16v, and G60) will dimensionally bolt to your engine and accept your starter.

:twisted: My dad exploded reverse in my AWY last night so I'm looking for a tranny too. Anybody in Ontario got something that'll work in a 92 Golf non-turbo?

Thanks, Steve

Judging by your choice of emoticon, I take it your dad's footing the bill for a new tranny.. perhaps one with a Quaife/Peloquin LSD, bolt kit, etc? :lol: J/K

Well according to http://www.scirocco.org/gears/, the AWY has 90mm driveshafts.

Quote

Via Drew MacPherson (on the scirocco mailing list):

Here's a chart of transmission code and axle flanges (A2 transmissions) from the VW parts catalogue. There may be some aaplications missing, butI tried to cover most of them. I did not specify gas vs diesel, but I think as a ROT most gas transmissions in Dijifant applications (ie 100hp and up) are 100mm flanges, while most CIS and Diesel applications (85-90 hp) are 90mm flanges.

90 mm flange
Code (Application)
++++ ++++++++++++
ACN (07/84-09/86 GOLF)
(08/84-07/85 JETTA)
ACH (07/84-09/86 GOLF)
(08/84-07/85 JETTA)
AGS (08/86-07/87 GOLF)
(08/86-07/87 GOLF)
AOP (08/88-07/89 GOLF)
(10/87-07/88 JETTA)
AEN (11/87-07/88 JETTA)
ASF (09/87-05/88 GOLF)
(09/87-05/88 JETTA)
4S (08/87-08/88 JETTA)
AWY (08/89-07/91 GOLF)
(08/89-07/90 JETTA)
AVX (01/91-07/92 JETTA)

They don't list the 4k, so I don't know what year those were made.

So I'm thinking the ASF would be what I want. There's a ton of them out there and as such they're cheaper. Almost the same ratio at the ACH as well. Does that sound like it would bolt up right?

What do you mean 020?

Thanks
Ray

020 is the housing style

I checked out the ASF but it has a 3.667 final drive. Regular diesels are 3.941 and the ecodiesel is 4.250

I have a TD so I have a *little* bit of power, so I think I can get away with that gearing...

be careful of the 3.67 final drive transmissions with the diesels. They are hard to get the car going in first gear. Try to find a 3.89 or a 3.94 if you can. You could always do some mods and put an old 7D or 7A in it (.71 5th, really nice on the highway). The AGS is the transmission of choice for the A2 diesel, but like you said, they are hard to find. You can also try an AOP (but 4th gear is a bit low and there's a big gap between fourth and 5th) which has the same final drive as the AGS and the same 5th gear. Also the AVX looks good (4.25 final drive, 0.75 fifth, same gearing as the AGS).

Can anyone else vouch for the 3.67's being hard to launch? I don't mean to sound skeptical, but it doesn't seem to me like it would make that big of a difference, especially in first gear. Plus, they're cheap :-)

Thanks,
Ray

I haven't noticed any problems with a 3.67, even with a normally asthmatic diesel. I'll be going back to the 3.67 final drive in mine, but switching to 185/60R13 tires at the same time.

It's a little taller in first, but not terribly so. Personally, I think 13.5:1 to the wheels is too low for first gear (that's 3.45*3.941), and all the transmissions with the 3.94:1 or 4.25:1 first gear tend to wind first out too quickly and have a tendency to spin wheels if you apply any significant power. With the 3.667 final drive, it's about 12.65:1 in first. That's not a huge difference, but it's noticeable. It still winds to high too fast in my opinion.

I do like 2nd with the 3.94:1 final drive, but I'm doing the hybrid close ratio 1st-3rd, tall 4th and 5th thing now, and the 2.12:1 second gear with the 3.667 final drive works really well.

Is 300CDN a fair wrecker price for a 4S? I don't know what the mileage is on it but I imagine it is pretty high...I looked at two cars today with over 500K km on each of them by the looks of the bodies and spare IPs in the trunks. They didn't even have their origional engines anymore so I wasn't willing to buy a gearbox from them.

Maybe I'll try a gas transmission since I can get an entire car for 300. When I'm driving the AWY in my non-turbo I'll lug around in 5th gear doing 50 km/hr so I may enjoy having the gas gear ratio.

Anyone else running a gas gearbox?

$300 is pricey. I know a place here where you can snag a tranny for $200 and they have a bunch of 0.75 fifth gear ones there. I'm in Toronto though so its a long drive from Sudbury (I believe 6 hours). A 4S is a nice transmission though. Perfect for a diesel. I wonder if the guy knows what he is selling. Usually you can't give the AWYs away except as boat anchors, but the ones with the tall gearing are worth money.

Chrissev: I'm all ears on where to get a good used transmission for that price. Woody's in Cobden is a VW place and so far he's the only person I talked to that knew the code of the transmission. He's also about the same distance from my place as Toronto. Everybody in Sudbury wants 350 for "whatever is in that there 92".

Is your contact pretty reliable? I don't want to show up in Toronto to find a grease ball transmission that's been to the moon and back after being told it only has 150K km on it. This is a pretty common practice from wreckers. :?

Cheers, Steve

The place I buy parts from is called Frisco. They have discount new stuff plus a garage full of used parts. Before you drive all the way out here, wait and I will call him on monday, or you can call, the number is (416) 736-9595 he will be able to give you a price but won't be able to tell you what transmissions he has probably. But if you call and you like his price, then I can always go over and see what he has, and tell you. His back garage is full of A2s waiting to be parted out and most of them are standard, plus he has about 50 transmissions sitting on the floor back there, a lot of 020s. I'd be very surprised if there wasn't one with the 0.75 fifth gear. The guy who runs the used parts area there is pretty good with knowing the condition of the stuff. He takes it out of the cars himself so he remembers where it came from.

Also you have to remember to put your search in context. You are looking for a transmission that is a minimum of 14 years old, and a lot of them are older. If you find one, out of a diesel VW that has 150,000km on it, I would say you are very lucky. Most of the good low mileage tranmissions that are available come from newer cars that have been in accidents. With 14 year old transmissions, they are either found in cars that have been sitting in the junkyard for years, or they come from cars that were recently driven, and are very high mileage. If it gives you any comfort, the AGS tranny in my jetta has almost 400,000km on it, and it still works, perfectly actually.

Cool, I'll call Frisco on Monday as I should have my transmission out by then. I want to be able to bring my CV flanges and a couple of other parts with me so I know I come home with the right transmission. :wink: If they have a couple to chose between I will be picking it up on Tuesday, ordering seals for it, and putting it in ASAP.

You're right about the types of diesel VWs found at wreckers, especially in Sudbury as they keep getting crushed after having the vacuum pump and struts pulled. :x Realisticly I'd like another 100-200,000 km from my car before turning it into a spare and getting another daily driver. The SMART cars should be pretty cheap by then and if we're lucky we'll also be able to get the Lupo.
