I have a 87 Doka with a 1.9TD. Great low end (probably could pull stumps)but I still have the 1.6NA tranny.
I can get a Gas tranny out of an 87 Westy (fire) Would the change in gearing from the diesel tranny to gas one help the top end (currently 110KPH)
Pros
Cons
Etc

diesels are usually geared taller due to the lower end power. stock, there isn't much power up top. you can install a gasser tranny but i doubt you will like it. look for a turbo diesel tranny and enjoy some good fuel economy
while taking advantage of the low end grunt of the 1.9

I built my aunt a TD and it uses a gas tranny. Just get the ratios and run the numbers. Some are better then others.

Is it a syncro?
I can assure you that you will not be happy with a gas tranny. the ratios will put your rpms even higher. This is not really desirable with a diesel.

Mine went from 4000rpm @ 72 mph to
3000rpm @ 72mph
Removed a AWY Diesel trans for a ACN coded gasser trans.
1st gear is just a tad tall but once I'm moving it rocks.

We are talking Vanagons here
Trannies are totally different.
I might also add that the ACN was used on diesel MKIIs as well

Indeed. But there are similarities in terms of gearing, and what you hope to get out of the vehicle. Here's a link to another forum from someone with a similar question, and my response:
http://www.vwdieselparts.com/forum/viewtopic.php?t=8389While I do not have a ton of experience swapping Vanagon/Transporter/Doka transmissions, I am familiar with the diesel gearing, and the 1.9TD swap (did it in my dad's Vanagon). I can't/won't tell you what to put in your car, but I will say that you might have to make a frankenstein trans to get what you want out of the car. Check the gear codes and play with the numbers, then decide what it best for you.

Not exactly. The ACH was the trans used in the diesel MKII. The ACN never came factory in any diesel

aircooled vanagon is the tallest gearing out there, gotta use your bell housing of course,

here you go:
http://www.brick-yard.co.uk/VehicleSpecific/T3/info/gbx.htmthis gives you all the ratio's for the different gearbox's. On the vanagon, the NA diesel boxes are very very low geared. Over here people generally try to find an AAP or AAR coded petrol box, off the 2.1. These are the highest ratio boxes as standard and suits the AAZ pretty well. Once tuned up, or especially a TDi conversion, you need to start looking at custom ratio's or final drives...
this is all for a 2WD though there are codes and ratio's for the syncro boxes there as well...

oh yeah, and you need to take the bell housing off your diesel box as well as the input shaft (shorter on the diesel) for the swap over.
Aircooled box is pretty good, not quite as high geared as the AAP / AAR but its a very strong box, probably the strongest...
