2010 crf450r jumping outta gear from 5th to 4th all other gears work fine


Terrence >>>> 1. Do not go through the gears while idling on a stand!!!
The rear tire is not moving at the speed that is normal for 4th or 5th gear..AND if you do get the tire moving that fast.. it is BEYOND DANGEROUS!!
This sounds like the 4th and 5th gears may need replacing.. or the shift drum detent for 5th gear has somehow become ineffective.. If you continue to ride this bike , you may cause more trouble and damage to the transmission.

Take this to a qualified professional!!

My voyager kicks and bucks at times when im driving down the road what could this be ?


How could anyone guess, at that question,without the vehicle?

It could be a dozen different things

The EGR Valve could cause the bucking,also ignition problems,vacuum leaks.

On a vehicle that old,I would look for something simple.

When im driving in 5th gear the RPM's seem high around 3500 is this normal?


I, also, thought this was high at first. After some research, I found that this car runs in that range at about 75 mph. So, yes. That is normal.

I HAVE A SLIGHT PURRING SOUND FROM THE ENGINE... WHEN I PUT THE CLUTCH IN IT STOPS... ALSO WHEN IM IN 1ST, 2ND AND 3RD GEAR WHEN IM ACCELERATING THERE ISNT A GOOD SOUND FROM IT!! BUT ITS FINE IN 4TH AND...


This would be most likely the first noise of a wearing input shaft bearing. It will only get louder, and eventual failure of the bearing will probably mean catastrophic gearbox failure. It stops when you put your foot on the clutch because the gearbox stops spinning then, and it is quiet in 4th and 5th because there is no side loading (as there is in 1st, 2nd, and 3rd) on the failing bearing. It wouldn't matter what sort of car it was, the gearbox should be overhauled as soon as possible.

Automatic transmission shifting problems


20 year old vacuum hoses are done. Replace all you can. The little plastic ones too. They control everything, transmission, computer, fuel, brakes, everything.

My 3000gt is stuck in 3rd gear why? this is a automatic


Your transmissions need to be service (fluid and filter change) and possibly a TCU replacement. Do NOT go to a dealer. Instead, look on ebay or craigslist for part outs. Transmission control units can be expensive but that is most likely the problem if you already changed ur fluid.
