shifting issues 2zzge

[<3myCelica]

i have a issue of shifting when its cold. it started a few weeks ago but now its really bugging me. so when i start the car in the morning (cold start), i cannot shift to any gears. the shifter is like stuck in neutral. however the car gets to normal operating temperature (the water temperature is at normal and the rpm is at 750-800) the shift is back to smooth where i can shift gears normally. So can anyone give me any advices to what is going on to my car?

I have shifting issues all the time when my engine is cold. <20 degree weathers. I've never had the problem of not shifting into any gears though. Maybe check tranny fluid... Couldn't say for sure though. How many miles do you have?

Try greasing the shift linkages on the tranny, see if that helps a bit. Check if there are any coolant hoses in the way of the shift linkages too. Other than this I'd look into the shift bushings.

my car has 116,xxx milage now. and thanks i'll try to grease the linkage and check the bushing and see if it helps.

It's normal for any trans to become "sticky" in cold weather. Not for it to stay in neutral though. My car has trouble going into 2nd when it's cold.

^I'm in Sacramento too and my celica doesn't have any issues going into gear in the morning.

Welcome to the C60 world.

ok so i tried greasing the shifting cable and its not helping. checked the bushings and its seems to be fine. any other ideas???

[themuffinman]

Cable doesn't mean squat when if its cold related. There's a hydraulic line attached to the shifter (before the cables). The cold will reign hell on it just like the cold makes the hatch shocks worthless.

Try this. http://newcelica.org/forums/showthread.php?t=23609&highlight=shifter

It's not related to the hydraulic line, but it might help a little.

thats for the clutch not for the shifter.

change the gear oil the next time you change the engine oil. gear oil needs to be changed every so often. whats happening is the gear oil has thickened up causing the shifter to not move very well till the gear oil is warmed up. once the gear oil is warm it shifts fine. change the gear oil to synthetic gear oil

thats for the clutch not for the shifter.

why is the shifter directly attached to the clutch? i thought that's what that extra pedal on the floor is for?

[themuffinman]

ah crap... double post.... sorry.

[trdmsprts27]

the hydraulic line is for the clutch cylinder that pushes the clutch fork and disengages the throw out bearing. the shifter is done by cables

[trdmsprts27]

which in turn is the reason for the clutch pedal so you can disengage the throw out bearing so in turn you can change gears

This line controls the clutch?

[themuffinman]

I stand corrected.

[trdmsprts27]

right those control the tranny but the hydraulic cylinder controls the throw out bearing that pushes against the clutch. the way it works is when the pedal is not depressed the bearing is pressed against the clutch firmly against the flywheel. when you press the clutch pedal it releases the bearing which in turn releases the pressure off the clutch and flywheel. as long as the throw out bearing is holding the clutch against the flywheel you cant shift gears but once you release that bearing you can

[themuffinman]

ya i know how the clutch and stuff works. I mistakenly assumed the cable guide as a hydraulic cylinder that assisted with easier shifts. It's all clear now. :thumbup:

[trdmsprts27]

nah its cool man we all make mistakes from time to time i do it alot lol

[themuffinman]

:faint:

[GSBoek]

any other ideas??? Check the shift fork/slave cylinder operation, might be that there's some bind that prevents the clutch plate from disengaging the flywheel completely when it's cold out.

thank for all the replies. however i just did oil change and transmission fluid change (redline 75w 90 full synthetic) and its the same. I can shift smoothly and freely when my car is up to normal temperature. but still when the car is cold i still cant shift it to gear. its seems as if my clutch is not engaging in the cold temperature. and there is no grinding when i shift. any other possibilities of whats going on?
