|As everyone knows, the Geo Metro convertible had a more peppy
transmission than the other Geo Metros. Since "peppiness" wasn't
what I was shooting for
|I pulled the 4.39
ratio tranny out of my convertible and replaced it with a tranny from a 1992
XFI (you can see the car on my parts car page). A few people
|warned me that the
XFI tranny was going to be geared too low and it would be a pain in the butt
to drive as well as actually cost me mileage. This really didn't
sense to me since I wanted to get the lowest possible RPMs while cruising.
Well, after installing the tranny I'm only turning 2200 RPMs @ 55 MPH
|instead of the 2500
I used to be turning (a 14% drop) the car feels quite sluggish. It is OK for
cruising but it kind of gets on my nerves for around town driving.
|As far as mileage,
it looks as though I gained about 4 MPG (from 45 up to 49 MPG). FWIW, I was
worried a bit about this before installing the tranny but the table
| below shows that the 4th gear in the XFI
tranny was about the same as 5th gear in the convertible. This meant that if
I didn't like
|the install I could
just drive around in 4th gear and it would be like nothing had changed.
would I do it again? Sure, but I bet I will be pulling the tranny out if I
ever sell the car (no one else would ever want to drive it like this).
