Change from 4-speed to 3w/OD

Ok.

The 833OD’s are fully synchronized just like the regular 833’s. As AJ said, it’s just a big split between gears. You’re shifting between a 3.09 first and a 1.67 second. If you’re not matching rpm’s that means a lot of work for the synchros, they can only do so much. And if you are matching rpms, it might take a little longer to match things up because it’s a big swing, especially dropping revs.

As far as strength, everyone sells the 833OD’s short. No, they’re not quite as strong as a standard 833, but it’s not as big a difference as most people like to think. Most of the components are the same.



Exactly! That’s a big split, you have to match the rpms better because the synchros can’t do everything. They’re not magic, there are limits.

Gotta work on that heel-toe brake/throttle action! :D



Not designed for it?! That’s exactly how they’re designed!

AJ is talking about matching rpms. That’s exactly how you do it, and it works because that’s how the design of a transmission works. Adjust the engine rpm to get the input speed to match the output speed and the gears slide together. You can do the math with a gear calculator to tell you what the splits are, and when you get familiar with your engine and gear combos it becomes second nature. A blip on the throttle and a firm shift on the lever and away you go! Doesn’t hurt the transmission at all.
