    OK, the J-type overdrive tranny is in and it WORKS!  I took the car
down to Britfest 2000 in NJ on Saturday - 230 miles round trip with no
problems, but I do have a couple of questions:

1. With the new tranny, my speedo now reads WAY higher than it did
    before, even when the O/D is not engaged.  Before, 3000RPM in
    4th gear was 60 mph - now 3000 RPM shows 67-68 MPH (but I'm
    quite certain I'm not going that fast).  The angle drive is new,
nothing
    else was changed.  What's causing this?

2. No matter whether I let up on the gas or keep steady pressure, the
    O/D seems to lurch into gear when I hit the switch (this happens in 4th
    gear - I never tried the O/D in 3rd).  The downshifts when I turn it
off
    are real smooth, but activating the O/D almost seems to make the
    car leap.  Am I doing something wrong and/or is there an adjustment
     that can be made?
