In 1970 Oscar Koveleski broke the shift lever on his McLaren at the Mid Ohio 
Can Am race.
$20 dollar part (in those days!) put him out.
1971 with Tony A-to-Z driving, came in 3rd behind one John Young Stewart and Jo 
Siffert. Much better. And much partying!
Cheers, Bill

  Wow! That?s a revolting development!


  One time when I still thought there was something to be gained by ?speed 
shifting?, I busted off the selector ball at the base of the shifter handle 
going into 5 at Road America. With my family cheering at the fence...I went by 
(and off) waving the gear shift lever in my hand above my head.

    I had a new failure this weekend at Lime Rock with the Spitfire. 1st lap of 
the weekend, doing a sedate warm up around the track under full course yellow. 
When I start down the front straight and put it in 4th gear, there's a big 
vibration and ugly noises (short video attached). I was flat towed back to the 
paddock and when I took the tranny hump cover off, I found the shifter had 
snapped (see picture). A little more poking around and I discovered the 
aluminum bell housing was cracked from side to side and two bearing caps were 
missing from the tranny end of the driveshaft u joint (replaced over the 
winter).


    I'm going to pull the tranny, driveshaft and diff to see what damage has 
been done. In the past, at the same spot at Lime Rock, I had a problem with the 
diff that 1st broke the tranny output housing. I didn't realize the problem was 
downstream, it locked up again (broken tooth inside floating around) and took 
out the rear  1/2 shaft u joints putting me in the wall.


    After rewatching the video, many times, I suspect the broken shifter was 
the cause of the problem, (2 gears at once?) not a result but I'm pretty sure 
disassembly of the tranny will confirm this. My question is, has anyone had the 
shifter beak like this and if so, was it caused by something else or was it 
just metal fatigue? 



    Other related info, new engine (1296) , more power than the old one, less 
than an hour on it. Zero track or dyno time, this was the 1st time the car saw 
4th gear. All drivetrain fluids changed over the winter. No disassembly but 
cover off inspections and hand turning tranny and diff felt normal, last used 
in October 2017 with no issues, with old, worn out engine.


    I will get this going for the K Cup, see you there.



    thanks
