 |

My tranny has begun slipping. Its got 180K miles No reason to believe its ever been rebuilt. Im just wondering If anyone thinks the AAZ was too much for it or if it was just its time to go?

Time for a rebuild.
Not sure what the Audi 5000 turbo has for torque but it's basically the same trans as ours.
Might want Audi planetary and clutches and a lower stall converter while you are at it.
I bought two Audi tranny's, one from a turbo car and the other was not. Both had more clutches than our vans and the turbo had the stronger 4 pinion planetary gears.

Can you confirm something that I am still not sure about
can you get the 4 pinion planetary gears with 26 splines(teeth) or 28 ?

I'd also be curious how does the tranny oil look/smell with that extra torque in the aaz your going to be heating that tranny up a bit more did you beef up the tranny cooler ?

Similar story here... I just had my tranny rebuilt (within a year of my AAZ conversion). I am not sure about the auto tranny but the higher torque engines need the south african oiling plates to be reliable over the long term. I was told by Arizona Transaxle that my tranny was really messed up to begin with though. I have receipts from previous owners that show the last two people to work on it before the rebuild were not VW tranny specialists.

You are saying that is an upgrade for a manual trans I assume ??

I have a large aftermarket oil to air cooler. To be honest I never drove the van enough to know if the tranny was any good before the swap. It may have been slipping already. Its not slipping really bad yet. But the thing leaks fluid like a sieve as well, It has done that since I bought the van though.

| Why would you put an old badly leaking tranny back in with a new engine??? If you have oil moving from one gear box to the other, the second will overflow and leak everywhere, while at the same time the other box will be low on fluid. |

Wow this sounds very similar to what I am going through.
I have an ALH mated to an auto trans. After 6 months on the original trans it started slipping.
I am on my third rebuild for it and I am worried about ruining another trans with the diesel engine.
Anyone know if you can get a lower stall speed converter for these transmissions and if that would help at all?
Cheers!
Dave

The earlier AC Bay engines used torque converters with a lower stall speeds and they MIGHT be a drop in replacement, but I have no idea if they would help. |

Never pulled the old tranny out. Was considering converting to a manual transmission. But am not sure at this time what I need to do.

Anyone know who the best auto trans shop would be to ask a question like this? Is there a better TC that would help with the diesel power pulses?
In MX I spoke with a guy that put high HP gas engines in bugs with the Vanagon auto, because he said they can take a beating. But after three tranny's I am beginning to doubt weather this was a good idea or not?
Cheers!
Dave

If you're looking at wrecking yards for a tranny replacement, keep in mind that you can use the automatic trans section from an Audi 5000. You'd have to use your final drive and bellhousing, but the trans sections are interchangeable.
I personally would switch it to a manual, but since you just spent all that time on the conversion, spending more time on a trans conversion probably doesn't sound too appealing.

When you get a new converter or have yours rebuilt you can request a lower stall speed. They change the fin angles to do that.
With more torque a converter stalls at a higher rpm. My stock "Z" converter with a Suby 2.2 is stalling at 3100rpms, too high for me.
I finally sourced all the Audi parts and am getting ready for my rebuild.
High stall speeds create more heat and less mpg during low speed driving.

see this thread http://www.thesamba.com/vw/forum/viewtopic.php?t=379502
talk to Jeff Field
http://www.transaxleengineering.com/Pages/Contact%20Us.html
They build the auto tranny mated to 500+hp sand buggy
http://www.transaxleengineering.com/Pages/Transaxle%20Pages/Sand%20Transaxles.html
& gawd knows how much torque but way more than your ALH
and if you want to go over the top they also have a adapter kit than allows you to take the torque converter from a Toyota Tacoma 4x4 truck(190 hp and 220 lb torque) & mate it to the auto tranny.
None of this come that cheap but a quality tranny rebuild w/o the audi parts will run ya 2k, their over build will be 3K with the audi parts & if ya want you can get them with the Porsche 930 flanges to mount 930 cv's
