Change from 4-speed to 3w/OD

When I said they were not designed for that I was referring to speed shifting. The only 833 actually designed for that was the slick shifted modified transmissions. Even then they can break.

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.
