Transmission & Differential - grinding sometimes? yea this doesnt sound good!!

oh so im driving down the road ive been having problems with the engine and turbo kit that the previous owner bolted on well i figured that out and the parts are on the way. however i still have to deal with the problem of it jumping back and forth quite alot when i let out on the clutch. and yes i do know how to shift. anyways i was going downtown and comin out of first gear i hear this whine. and as i excellerate it goes along with the engine pitch. and this sound is not very faint. i **** into second and it went away. later im driving and it does it again. i was hoping it was snow on my the fender rubbing the wheel but no luck i to it a car wash and melted everything off. same thing also later i was cruisin along in 3rd and i let off the throttle and it jumps out of gear, not like a big jump but enough to take it out of gear (syncronizer possible?) i dont know first time i have heard this since i have owned it which isnt that long but just trying to work out all the stinkin bugs in this thing!!!! this may cost quite a bit to huh....[sm=smiley35.gif]
thanks any guess of what it could be other than the trans would also help oh and it doesnt just do it in first either

Yeah, it sounds like the synchros are shot to hell. Could be a result of someone trying to powershift it a bunch, or of not changing the tranny fluid often enough... it could have come from a number of things.

oh also i got a nice little leak thats occuring if things couldnt get any better! i was wondering is this the main seal leak its coming from the other side of the flywheel but is covering the inside of the bell housing.(possible being slung by the fly wheel? man this sucks any way you put it.

hahahhahahahahahhhahahahahhahaahhaha[sm=roll.gif]

haha well guess i should have casught that one owell lol drrr... anyone know where i can get a resaonable rebuild kit for a decent price that will hold my engine? the trans is a SI and i think it might be letting go on me.

also what other years of trannys will fit the 99 civic ex?

any tranny from a sohc 92-00 should be fine, but one from a vtec car will have better ratios. it also sounds like whoever last replaced the clutch may have neglected to resurface the flywheel, that causes the shudder when engaging the clutch.

found this site they all say its the bearings?

Very unlikely... that wouldn't explain it coming out of gear. They could be shot too, but I doubt if that would explain your problems.

well i think its kickin out of gear because the syncronziers are get to be shot because of the loss of fluid. and i think its whining becasue of the bearings. thats just what i think anyone know for sure?

my stock tranny went out because of a chunk missing out of the bell housing. over time, dirt got in there and ate at the input shaft bearing, which, when it went out, WENT OUT. it took most of the tranny with it. it wouldnt stay in any gear cause the bearing would let the shafts move enough to prevent the gear from locking in, so it just started tearing the hell out of synchros and stuff.

U need to get a used tranny from japan for like $2 or 300 and elimnate ur probs all together!

well im going to buy a tranny now, not for sure where, everyone keeps saying to get them from japan but i have no idea wheres those sites may be, any suggestions? or does anyone have one laying around lookin for a 5 speed civic ex 92-00 that fitts on a d series motor. thanks

Hey where did you end up getting the transmission from? Where did you call? Thanks in advance.

I have grinding problems too\ but my car is all stock. Every time i rev my engine up to 4000rpm and and shift it into 4th gear it will grind. No matter what no matter how you let go or press down the clutch it will always grind going to 4th gear at 4000rpm +

Anyone know what might be the problem???

synchro is bad.

I agree with sacicons.

However, red_sleeper's problem with it popping out of gear is not a synchro problem. A synchro's allow the collar and the gear to make contact before the teeth on the gear make contact allowing it to slip into gear with out grinding. It is the angle of the teeth on the gears themselves that lock it into gear. By letting off the gas, if it jumps out of gear, this is an indication that "that gear" is worn and needs replaced. A synchro kit will cost around $100 for the entire tranny, where a gear set (1st, 2nd, etc) will cost about $100 per set. Not cheap. And not simple to fix.

So good find on the tranny red_sleeper.

So I'll have to replace the fourth gear right??

Considering the amount of labor charges a tranny rebuild will incur, not to mention the chance of a screw up in the reassembly, you're better off just buying a new (used) tranny.

So its really easy to screw up on the reassembly??? about how much does a used one go for??

What year/trim be your car?

its a 94 EX

You can get a used imported tranny for peanuts. $300 or less guaranteed... well, assuming you don't live in the Arctic circle.
