<DIV>It's mostly the final drive gear ratios that are different. But it's also
the size of the CV joints too (they're larger). Add in that buses and type 4
cars used a "mid mount" for the trans (hangs from the body), just makes the
shape of the differential housing look different. We did some searching on the
Samba earlier this year (there's a thread hiding on there), on the differences
in torque converters between the 3 models, and found they are very similar and
"flash" at around 2200 rpm +-50 rpm. Depending on the model, it can "flash"
about 100 rpm more, or less. That' s it. The "flash" term means when it starts
to engage, in case you're wondering. The discussion started, as someone was
looking for a higher "flash" TQ from a bus, for their T-3, and everyone went
digging only to find out, a bus didn't "flash" at 2800 like was thought (like
the OP was told), but at a much lower rpm. I hope this helps.
