Transmission Problems

[NEMO]

transmission is locking me out of gears at high rpms(7000-8500). it shifts fine at lower rpms(>7000).

what could this be? synchronizers? bearings?

[highspeed]

synchro's.......but you might want to give some more info about which car it is, what transmission, clutch, etc............

[green91]

brandon you are the man! btw i got another 240 lol

[NEMO]

its a honda civic with a honda transmisson

[green91]

Most likely its your syncros. Does it do it in all gears? Try a fluid change first.

mainly 4th but it did it in 3rd the other night.

[green91]

Yep, especially when its gear specific its most likely the syncros. But 3/4 do also share a shift fork, its possible you've got a bent fork.

lol

[EmminoDaGreat]

I would consider this to be the synchro sleeves (hubs), but I would only know by taking it apart. Or even the actuall teeth on said gears.

[NEMO]

i know for a fact that the bearing is bad #15

what did it do heat up and lock up?

what did it do heat up and lock up?

i was racing and when i shifted to 3rd it locked me out then rpms went down and it went into gear then when i shifted to 4th it did the same thing.

when i am just driving it shifts fine

[NEMO]

could having to much fluid in the tranny cause this problem?

[Black R]

Nope

syncros

And sleeves

time for a rebuild

I'd check the gears gor wear and tolerances also

[Drummerboy]

I had this problem in 3rd/4th in my eclipse. It was the synchro and 3rd/4th shift fork. I heard that resting your hand on the gear shift while in a gear (specifically if its one of the lower ones of the gate) that it can cause wear to the fork. Not sure how true this is.

Its sounds like your clutch. My stage 2 did the same thing. As soon as I put the stage 4 in it went away. We even tore the tranny down and the syncros were fine.

I have a stage 4 cc

[CaTcH22]

How many miles are on it? Are they hard miles?

[NEMO]

i put about 300-500 daily driven miles on it before i ran it hard like cc told me to.

[NEMO]

sorry for the cell phone pics but got the transmission pulled last night i took the case off and this is what i found. as i already knew the bear was bad but not this bad. as soon as i remove the case the bear came apart.

as you can see in the 2nd pic that is the bearing stuck up in the case.

the 3rd pic is a pic of one of the gears. if someone can make it out are the gear supposed to have the notches on the end of the gears?

[EmminoDaGreat]

Yes the notches are normal. does that bearing spin? if so its probably fine, they get stuck often, a few taps with a rubber mallet will make it come out, makes it easier to reassemble.

i will try that when i get back to the house. but i think the bearing was starting to come apart. why would the bearing come off the shaft and be stuck up in the case?

need to hurry and get her fixed so you can get that mach1 dude to shut up lol

[NEMO]

very true

[imprtguy_94]

very true

lol believe me im not the only one waiting for it

[NEMO]

lol believe me im not the only one waiting for it

oh i know. thats why i need as much help with this tranny as i can get. basically trying to figure out if its a simple fix or if i should buy a new one

[civicturbo10]

i bet it's synchros. My high mileage hydro was wore out and the cost of parts justified getting a another trans. OE parts started to add up quick and it just needed this that and the other after starting to tear it down for a close inspect....

[all-mota]

it's completely normal for that beraing to do that it becomes stationary when the top half of the case is torqued down.

check you clutch make sure the springs on the plate are good and check the fingers on the pressure plate to make sure they aren't bent causing the clutch not to release at high rpm that will lock you out everytime
