#4643, "gears are all messed up"


          

alright, heres the story. Since I first bought my modded eclipse RS, ive been having shifting problems. To aid the problems i have done the following. new shifter cables, short shifter, shifter base bushings, and bled clutch fluid.

these are the problems

1.) Car was locked in third gear. Pulled cables off the select levers and found out the select cable was froze. Bought new shifter cables from dealer and car goes into gear nicely under 3k rps.

2.)Car rolls/creeps foward after high revving when car is in gear and clutch pedal is pressed down. if in a gear at a stop and i rev over 4k rps ill creep foward! plus if i drive hard and then come to a stop with my foot off the throttle ill creep foward if in gear.

3.)When I go into high rpms and try to shift fast the gears are hard to get into. When shifting from 1-2 it is tough to get into gear and sometimes results in a grind. The 2-3 shift is also hard but third gear seems to move to the right and i miss the shift.

4.)After high revs and going fast, all of the gears become harder to get into.

All of the gears go in so smoothly when the car is off. Only when the car is driven the gears are hard to get into. Also the shift lever has about an inch or more of freeplay up and down. I traced the freeplay to the select lever on the trans...how bad is that.

Does anybody know what the real problem is, or what is causing this. I was told that a bearing in the transmission was shot. i dont know if its the TOB or some other bearing im ignorant of. Or the clutch is not disengaging right. Im hoping that its not a internal trans problem. Wednesday a clutch is comming in and the trans will be dropped. Maybe i can find some evidence then. Can it be a bad master/slave cylinder (im not having any pedal problems). I have no idea what forks or pivot balls are. What are those and what can go wrong if they broke.

If you got this far in reading my post i already thank you. I try my hardest to help people by giving them advice to their problems that i went through myself. Can any of you guys get me out of this conundrum so i can finally drive my car with a smile?

I could put... I could put... strychnine in the guacamole.

Sounds like you've got some bearings on their way out, which is to say, an internal trans proble,.

Well thanks darkone, ive read up on some posts similar to mine and your responses to them are pretty knowledgable. I heard from my boss that a bearing could be the problem too. This sucks for me i was really hoping to only hear that it was a clutch or hydralic problem. The bearing that you say is on its way out, would that be an output shaft bearing? or some other one? Looks like im getting a used trans now. Thanks again for your input.

All the speed gears ride on small needle bearings. When they get gummed up, worn, pitted, etc, they cause symptoms like what you are seeing - hard to get into gear, creeping, unusually noisy, sometimes even sticking in a gear.

Try changing the fluid first, using dealer-supplied fluid, and it might clear up.

hey darkone... would replacing both the master and slave cylinder do any help to my problems. I noticed whenever i double clutch or rev high and press the clutch in, give it a few seconds, it will go into gear easier. also i noticed that if i shifted, say "1st to 2nd" over 5000k and kept the tach at about 4-5k that after a few seconds the car will go into gear. but nothing fixes the idling at a stop. Im thinking not enough pressure is building up for the clutch pedal to do its job of engaging and disengaging. Tell me if im wrong but a R/R on my trans is the last thing i want to think about! thanks

I could put... I could put... strychnine in the guacamole.

based on your symptoms (gears clash from one to the other, grinding, creeping forward, etc) you either have low fluid, or the clutch isnt disengaging. could also be an internal problem with the synchronizer assemblies.

do whats called a clutch spin down time test. run the engine at idle, gear in neutral, clutch engaged. disengage the clutch, wait 9 seconds and shift into reverse. if grinding is heard, check your clutch system for worn and broken parts and obviously replace any you find.

since you said you'll have the tranny out soon anyway, go ahead and check the input shaft end play and see if thats in spec. that will tell you if any of the mainshaft bearings are toast or not. i dont think its a bearing however, i think its the clutch.

like this right here, either you're low on fluid or the clutch isnt disengaging.


"The 2-3 shift is also hard but third gear seems to move to the right and i miss the shift."

check the gear selection mechanism while its out. the shift rail may be worn or broken and the shift fork bent, worn or broken. really easy to inspect the synchro assemblies when you're in there as well. is there any brass gold colored shavings in your fluid?

to turbo8u.

ill do what you told me tommorrow when i have some sunlight. im hoping that im not low on trans fluid because 3 months ago i topped it off and i hope to god theres not a bad axle seal. do you think at all this problem can be caused by a bad hydraulic system too? and btw i replaced the shifter assembly about 1 month ago due to a frozen line.

I could put... I could put... strychnine in the guacamole.
