Gear shift is a hard "bang" from 1st to 2nd - not as severe in higher gears. Is this normal. Bike 2007 - C90 12,000 KM

sounds like shift lever adjustment problem
take it into a service center and have it properly diagnosed and a quote

change its gear outer wire and its clutch plates after changing i thing your problem will solve

most 4 speed shifters from 2nd gear to third gear, go up and to the right side. The linkage may be not be lubricated and binding up with 1st and 2nd gear shifter rod.Put car up on jack stands in front, and have some one shift through the gears, and see if shift rod is binding up.It may also be bent. Put in 4th gear, and have some one down shift from 4th gear down to 3rd, and to 2nd.If not bent, keep shifting through all the gears. If rod is bent, replace. I hope the clutch is good. Dont try to bang the gears hard. Hope this helps

This may be normal but you can adjust your driving to reduce the impact. To speed up the warm up process of the catalytic converters, the power train computer holds first gear a little longer than normal. This causes your car to get higher in the rpm range than normal, at part throttle, which causes the hard shift. On your first drive, try NOT to accelerate while the car is in first gear--it won't take long for you to learn how far this is.

From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

the transmittion keeps shifting in & out of gear between 45 & 50 mph it shifts to a higher gear then a lower then higher then lower till I get above 50 mph whats the problem & how to fix it

drain and fill trans with fresh fluid
trans may have to be rebuilt

sorry

what year is vehicle please ?? as people often put it in wrong catagory ,if its mazada 2007 then its dealer only as a computer controls it all and the software is factory encrypted to stop general garages from repairing it .But check for a vacumn pipe loose under bonnet ,thin rubber pìpe from inlet manifold to gearbor or a diaphram switch,

It will be hard to shift or find neutral if the clutch isn't adjusted right. check your adjustment first.
