VW Bus Engine Swap to AUDI 5E

Which Gearbox to use?

This are tables of gearboxes available for Vanagons, as far as I heard about. There are eight main sections: Gearboxes for the aircooled boxers, four speeds for the waterboxers, four speeds for the Diesels, five speeds for waterboxers, five speeds for the Diesel, gearboxes from South Africa, and some automatics.

First the early 4-speed boxes for the aircooled gasoline engines:

Type	091	091	091	091	091	091
ID character	DH, DN	DH, DN	DK, DP	DJ, DO
For engine	1.6L	1.6L	2.0L	?.?L
Power	37 kW	37 kW	51 kW	?
Year	78.7-79.12	> 80.1	> 78.7	?
1. gear	3.78	3.78	3.78	?
2. gear	2.06	2.06	2.06	?
3. gear	1.26	1.26	1.26	?
4. gear	0.823	0.852	0.852	?
Revers	3.28	3.28	3.28	?
Transaxle	5.43/5.86	5.43/5.86	4.57	?

The boxes with ID character DN, DP and DO includes the differential lock option. The DJ and DO does have special gear ratings for mountains, but at present I do not have the specifications.

Second the early 4-speed boxes for watercoled gasoline engines:
