[Vwdiesel] Vwdiesel Digest, Vol 43, Issue 2

[David Cook]

According to Brian's website
<http://tinyurl.com/2nc5zw>, my transmission is a 7A
made in '84.  

Judging by the speed in 5th at 3500 RPM, I don't have
the worst one ever, but it definately could be better
as well.

So, I guess what I'd really need to find would be a
good used FF or FN.  There are a couple european
transmissions that would get another MPH, but they're
european.

With the original question, I was thinking that it
would probably be cheaper (especially when considering
shipping too) and easier (not R&Ring a trans) to just
buy a 5th gear.

However, I notice on the right end of the chart, there
are several other transmissions that might fit.  It
might be worth a trip to where the wrecked Cabriolet I
have is to see which one is in it.  It is a circa '85
Cabriolet.

As an interesting sidenote, when I was first deciding
which trans to use (when I did the diesel cabriolet
conversion-either the cabriolet's trans or the
rabbit's trans) I discovered that someone had swapped
in the exact same diesel rabbit trans to the
Cabriolet, so there was no difference!
