I don't have much information on that particular model, but from what I could find it seems pretty stout. With regards to shifting- Well- yes and no. None of these gearboxes are actually designed for shift-on-the-fly. There is no syncro mechanism, just indexes on ever gear at 90* for the shift keys. Generally they will tolerate gentle shifting at low speed pretty well, but once you get into higher input speeds you are really taking your chances. Some people seem to have more luck than others in getting away with it, but I don't advise it.

From what I've noticed, overspeed input trannys last longer on key wear. Less torque on the keys than our transaxles, which use gearsets inside to speed up the transaxle. We are replacing keys about twice a year on the modified ones.

Stock, overspeed transaxle, 35mph top speed, we never wore out a shifter key. Blew gears, cases, bearings, and axles, but keys held up fine.


Another thing is shifting style. We put a kid on one of ours, he had the keys shot in 1 hour. I've got 40+ hours on my keys at the moment. Always use the clutch, ease out the clutch until you feel the gear engage when starting out. Then you can push the clutch back in if you want to do a high rpm take off.

When shifting at speed, use clutch, and you want to feel through the shifter when it engages the next gear. Let clutch out, but be ready to push it back in incase you are between gears. If you give it the gas inbetween gears, engine will rev up and BANG, keys will drop in. Not good for gears or keys.

Don't downshift until you are almost stopped, or engine speed is slow for the gear you are after.

We have to shift on the fly, no way to start out in higher gears. Matter of fact, I always shift up through the gears, starting out in whatever gear is best for the terrain. 1st, 2cd, 3rd, and sometimes 4th.
