A3 020 tranny into A4 for 5 speed tranny swap?
Just wondering if a 020 tranny from a A3 TDI would work in an A4 TDI?
It looks tricky, and probably not worth it.
QUESTION: Are the 020 tranny Speedometer cable threads and interface the same as the 02j?
QUESTION: Are the 020 tranny mounts different?
Some research results:

“CORRECT ME IF I'm WRONG:
020 - Mk1, Mk2, Mk3, Scirocco, B4 passat 4cyl gasoline engines,
02A - Corrado, B3 Passat, B4 passat TDI & VR6, Mk3 VR6 & TDI
02J - Mk4, B5
02M - 6 speeds from Mk4's”

“02j and 02a transmission are interchangeable. some of them require replacing the flanges. but is very easy to do with a sledges hammer and a chisel.”
“020 Trans Speedometer cable gears:
020 3.9= 171 957 821 A (WHITE)
020 3.6= 171 957 821 B (RED)
020 4.2= 171 957 821 C (Green)”
“in case it was driving anyone else bonkers as well- the bolt for the 020 speedo gear plate (that holds the cable into the tranny) is M7X1.25- a thread pitch that is incredibly difficult to find in places other than the dealer. thanks vw! the bolts that hold the lower inspection plate to the bellhousing are M7X1.0, some hardware stores will carry these.”
“ok, 020 gears and 02a/02j gears WILL NOT INTERCHANGE. now alot of stuff between 02a and 02j will interchange, but I don't know all the technicalities here. I think al the 02a/j gears will interchange, and also 02B, 02C, and 02D tranny internals for the most part”
[FONT="]“The case of the O2A/J is actually shorter then the 020's. [/FONT][FONT="]The O2A/J's are pretty similar on the outside, but not exact, as we found out. The casting around the diff case has a bit more meat on it, as well as the casting for that we use for the sidemount.”[/FONT]
