84 Honda trx200 will not down shift into neutral

check the joint where the shift linkage attaches to the shift shaft at the transmission....you either have a pin missing in the joint or missed the splines when making the connection at the shaft...........Make sure it is in neutral at the shaft and inside the car at the shifter before making the connection at the shaft.............

I think uve gt enuf answers but i wud check release bearing

im going to say your clutches are going bad

can i assume you pulled the side plug on tranny and the level
is right there? or gone way down, ever do a 50k service? to it?

M/T tranny (not auto) what engine? the m./t varies by HP of ENGINE.
If its really in 5th ( i bet not)
if the RPM rises fast that is called clutch slip
yes, clutch bad.
if not in 5th actual rpm will rise fast too. slip,
if the other gears wroke like 4th at wide open throttle up hill
gee the chutch is good.
so its not going in to 5th (for lots of reasons)
but 1 reason , is easy.

-AX 4/5/15 transmission
this tranny has a shift tower. (that thing on top that the shifter lever
fits in to)
most tranny that fail to actual shift into gear
is caused by a $1 plastic part failure
so pull the shifter off top of the shift tower.
and look, is the plastic buffer parts all bad, missing, cracked or
destoryed, sure they all end there... all.
i can also remove the shifter, lever.
and shift to 5ht by hand, and see that it DOES.
it either does, or does not.
if it does, the lever parts are bad.
that simple.
see part 61 (im guessing which of 5 tranny it is , )

does it lock up in any gear? sounds like blocking rings trying to stick, what type oil did you put in it?
should take auto transmission fluid

Hi:
The shift pattern is pretty much the same on all 5 speed cars. The top row is the odd numbers, 1-3-5
the bottom row is 2-4-Reverse. The center position is neutral

Here is the key: The shifter is slightly spring-loaded to the center position. If you hold in the clutch pedal and pull the shifter to neutral, and let go of it, it will automatically be lined up in the position, that if you pushed it forward , it would go to 3rd gear, and if you pulled it back, it would go into 4th gear.
This way, to start driving, you start out in neutral, grab the shifter lightly, and push it first to the left, then forward. This is first gear, where you start out. when you want to shift to second, push in the clutch, and keeping left pressure on the shifter, pull all the way back . Here is the easy part, 2nd to 3rd. When you are ready, push in the clutch, and just push the gear shift forward , till it hits neutral, and is spring loaded to the middle. Then you just push it straight forward to 3rd, then next shift, straight back to 4th.
Last gear, 5th: push forward to the neutral row, then Push to the right till it lines up ,and forward to the 5th gear. Reverse should only be shifted into from a dead stop. Find neutral, push the shifter all the way right, then pull back towards you. Hope this helps.
Practice a bunch in the driveway!

If its a 5 speed, the clutch is going bad. The pressure plate becomes weak, and prevents the transmission from being able to be shifted into gear.

howdy,you need a clutch..thats for sure,101%

my old honda did that too. replace the clutch, it's probably the pressure plate.
