My 1994 stealth wont go into any gear while running but will when not running.why?

99 00 01 02 03 FORD F150 MANUAL TRANSMISSION 5 SPEED MAZDA-TOYO KOGYO 4X2 8 CYL

will it shift if you double clutch ?

might be a shift linkage adjustment
internal shift fork has broken a scroll pin

clutch fork movement ok ?

Just a suggestion here but my son was experiencing the same problem with his Toyota Celica. We replaced the clutch and throwout bearing and MC, had me stumped for days the I pulled back the rubber boot on the MC where the it comes through the firewall under the dash and saw that there was fluid leaking into the boot so basically the MC was bad an it was bypassing the metering valve causing the fluid not to push the slave cylinder all the way down for engagement. On another car ...a 97 Saturn SL it wouldn't shift into gear, also all new clutch components. Wound up being a bad top right side motor mount was bad. engine was sagging just enough to cause the clutch not to shift properly. I hope this helps.

Can you verify that when you push the clutch pedal to the floor the slave cylinder is moving the pin that goes between the slave cylinder and the clutch fork. It sounds like the clutch is not releasing properly.

if you bead the system and still have no pedal action the master cylinder would be bad if the fork arm is moving the pressure plate could be bad

on the transmission there is a slave cylinder that works like a brake cylinder, when you apply pressure to the clutch pedal a rod inside the vehicle under the dash pushes into a clutch master cylinder, (almost like a brake master cylinder without the reservoir, as the clutch master cylinder works off the brake master cylinders reservoir) the plunger in the clutch master cylinder applies fluid pressure to the slave cylinder,(located down on the trans near the clutch fork assembly) which projects a piston rod into the clutch fork dis-engaging the clutch. To bleed the clutch slave cylinder locate the bleeder screw on the slave cylinder,break loose so it loosens and tightens easily. Check fluid in brake master cylinder reservoir,fill if needed, while bleeder on the slave cyl is closed have a helper push clutch pedal to floor and back 7-8 times, (At first the clutch might stay at the floor, just pull it up by hand or foot and continue) after several pumps with no rest time push pedal to the floor and hold down with foot pressure, at this time loosen the bleeder on slave untill fluid leaks out, watch for air bubbles, close bleeder and repeat untill there is no sign of air bubbles, (make sure to check fluid in the brake master cylinder and keep fill as needed, do not let fluid get less than 1/2 empty as it might **** air and you will have to start over) If this does not bring clutch to operate then you need to check if slave cylinder is reachig its full extension of push rod or not. If it is not then you will have to replace the clutch master cyl or the clutch slave cyl or both as seals are bad and wont hold pressure. Or you need to inspect the clutch fork,the throw-out bearing, or the pressure plate fingers and clutch plate for failure or broken bent parts. I hope it turns out to be a easy fix on that clutching thing.

Was the fluid low? Does the pedal have any resistance? does it feel normal? Did it happen all of a sudden? Does it shift into gear with the engine off? You say it doesnt shift into gear, but does the shifter move into gear or not? Or it does and the truck wont move? Sounds like maybe the SLAVE CYL isnt operating? leaking? theres more questions to answer.

try to vacuum bleed the system at the master most hand vacuum kit come with adapters to fit over the master reservoir otherwise the system may need a new master or you may have a leak

Have someone push the clutch pedal while you watch the slave cylinder to see if it is pushing the clutch fork far enough. If it is not, then you will need to bleed the system again. Only use Dot 3 non ABS brake fluid (don't mix em). If it is moving it, then there is damage inside the bell housing.

Clutch is your problem, its not disengaging all the way, hydrolic clutch? chk. resavor for fluid, maybe air in line, bad slave cyl., or clutch is bad, manual clutch linkage needs ajustment or clutch.

Your clutch is not disengaging. If it a hydrolic clutch chk. the fluid in resavor, Or slave cyl. for the clutch is bad, Or it has got air in it and needs to be bleed. This is a clutch problem, nothing wrong with trans. If its a manual clutch linkage its an ajustment thing. My best guess if its hydrolic slave cyl. went bad, or resavor is out of fluid.
