Men:
My 92 Jetta Ecodiesel with 208,000 is getting ready for a new clutch. Since I drive interstate all the time, I'm interested in swapping in an ACN or ASF transmission instead of the AVX. From all the charts and etc I've found, they all have the 90mm drive axle flange and the 22 mainshaft bearing. The ACN or ASF will drop my rpm at 65mph from 3000 to 2600. So, is this just a drop in transmission trade? bolt holes, mounts, linkage etc the same on these models? Anybody have one for sale? thanks

I think that I have a 85 ACN. I don't know if its a drop in.

Think Twice
I did this not too long ago and after having studied the gearing chart carefully I decided to go with an AGS code tranny and then had 5th gear swapped from .75 to .71 I'm happy with the results, but If I had to do it over, I'd go with a transaxle from a MK3. I haven't logged less than 50K miles per year since several years ago, and I usually hold 78-80 MPH on the highway. Only wish I did it sooner- like the day after I bought it!

If your not real power hunger like me you can go for one of these,ASF, AON, ACN, ACL. They all the same and have the lowest final drive of 3.67. Then do the 5th gear swap to .71. When you cruse at 60 you will be doing 2250rpm. Nice and quite. Mileage should jump up about 5% to 7%.

It is a direct bolt-in swap.
Depending on the year of the trans axle you swap in you might have to change the reverse light switch as the electrical connector could be different, use your old one. The wiring changed part way through 1989 (exact month varies by model) from CE1 to CE2. The axles are the same (90mm), as are the mounts, shift linkage, etc. While you are swapping put in new output shaft seals and also take the opportunity to replace the shifter bushings.
I have an ASF mated to an Eco (was an AVX), I have no problems with the low 1st & 2nd around town.
80MPH @ 3,000 RPM Tire size 195/60-14

The trans axle has ~195k on it and the final has gotten a bit whinny. Later this year I plan on pulling it and sending it to Broke VW for a rebuild and to have the 0.75 5th swapped out for an 0.71.

sort of, I haven't swapped to an LDA pump yet, the CAT was already gutted when I got it.
