Toploader at the Track

[fastd]

Rick,

Thanks (as always) for your insights.

I have looked for coolers for manual toploader transmission but haven't been able to find any. If that set up is $600, wondering if I should try to upgrade to a 5 speed that won't overheat...or do you think any transmission will overheat given the lack of air flow?

A 5 speed might be sweet in this car; right now I have a 4 speed with 3.50 rear gears, if I went to a 5 speed and could put the 4.11s back in there, very curious what that would do to performance.

Regards,

Phil

I'm by no means a expert on these matters, but I have a Toploader on my Kirkham and after a hard day at the track, I had no such problems with mine and I don't ever recall hearing about gearbox cooling problems on original race cars.
Could it be that the shifter linkages aren't correctly adjusted and the extra heat is exacerbating the problem? I think it would be worth checking the linkages first to make sure they are spot on.
