I have a 1992 Chevy Silverado 1500 with a manual transmission that I have replaced the clutch master cylinder and the slave cylinder in and it still don't want to go into gear when it is running but it will go into gear when it is not running what else could it be and the clutch pedal is stiff the way it should be and we replaced the clutch throw out bearing and the pressure plate also
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
You should first pump the clutch several times and then hold it down and release air from slave cylinder. Retry the clutch to see if clutch releases. If not then turn off vehicle and put transmission in gear and hold down clutch and make sure your direction in front or behind you is clear and crank motor to see if clutch is free to turn. If still not free then you have ha defective pressure plate and need to replace it. Before that look inside transmission inspection hole and have someone push clutch and see how far the release bearing is moving to release clutch pressure plate. If it does not move much then you have a bad clutch master cylinder or linkage. If it move more than an inch then you have a bad pressure plate a long as release bearing is pressing it in.

The first thing to inspect is your entire clutch cable. They may be worn out over time, or simply need to be lubricated with special oil or powder. After the cable is lubricated, you also need to re-set the cable and adjust it to your convenience.
In most loose clutch cases with a hydraulic system, it is a probably an issue with the master cylinder. Internal or external damage to the cylinder can cause the hydraulic fluid to leak out and it simply will not perform properly once the fluid is too low. Sometimes, it is simply a worn seal that needs to be replaced.
There are typically a few different possibilities for why a clutch pedal will stay on the floor. It could be a failed clutch master cylinder, slave cylinder, failed fluid line, or the clutch has failed.
Trapped air in the hydraulic line. If there is air in the hydraulic line, then it can cause stiffness in your clutch. Air usually gets trapped inside if there`s a leak somewhere in the line. This causes air to enter the system and can make your clutch pedal harder to press.
If your clutch pedal feels soft or `spongy` at any point as you press it to the floor, it`s a sign your clutch fluid is low. That spongy, inconsistent feeling is due to air in the clutch line from the master cylinder to the slave cylinder.
Go under the vehicle and check the condition of the clutch cable or hydraulic lines. Make sure that the cable is tight. If you have a hydraulic line, make sure that there are no leaks. Step 2: Check the slave cylinder if your vehicle has a hydraulic clutch pedal.
If your car has a manual transmission, then an inability to shift into gear could be due to a worn out or broken clutch. The average clutch should last at least 60,000 miles before wearing down, and many will last well past 100,000 miles.
A soft clutch can be a clear sign that a replacement is in order. As your vehicle`s clutch wears down, it may begin to feel soft and spongy when you press down on it. This inconsistent feeling is a sign that you should bring your vehicle into a shop to get it looked at.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong. Don`t get left at the side of the road with a vehicle that won`t shift into gear.
You have to press the clutch before the brake pedal if your speed is less than the lowest speed of the gear you are in. You can find the lowest speed of the gear by simple releasing the clutch and not using the accelerator.
If the pedal is released quickly, a definite lurch can be felt as the engine and driveshaft re-engage and their speeds equalize. However, if the clutch is released slowly the clutch disc will “slip” against the flywheel; this friction permits the engine a smoother transition to its new rotation speed.
Manual Clutch Adjustment

The rod will have a locknut and an adjuster nut to determine the amount of free play the clutch pedal has. Locate the nuts so you can adjust them by loosening both slightly. Pull up the clutch cable again so you can feel a point where the clutch fork engages.

My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I replaced the clutch but the pedal sticks to the ground and won’t go into gear
ANSWER : Hi. It sounds like the clutch master cylinder and the slave cylinder has gone bad. Both of these components aid in shifting the the car and effect the clutch pedal effectiveness. There could also be the possibility that the throw out bearing is not aligned properly causing this issue as well. I suggest replacing the clutch master cylinder and the slave cylinder and re-bleeding the system. I think this should solve your issue. We do have certified techs at YourMechanic who can help you with this issue.

Loose gearbox that won’t find 2nd or 5th gear, sometimes hard to differentiate between 1st and 3rd.
ANSWER : There are a couple of possibilities. The first thing that comes to mind is of course the shifter itself. There is a nylon ball and socket joint at the base of the gearshift lever that sometimes falls apart, making the feel of the shifter very vague. Additionally, there are links to the transmission shift linkage that involve nylon bushings and joints that can fall apart. Both problems are very common on your car. The other less common possibility is that you have a bad motor mount that is allowing the transmission to move around too much when you try to shift gears. either way, it’s not a big deal to fix, and probably won’t require expensive transmission work. If you contact Your Mechanic, they can send a technician to your home or office to check out you shifting issue and let you know what repairs it will take to correct it.

My pedal makes a grinding noise and gears get stuck
ANSWER : It could be that you haven’t gotten all of the air out of the system. Bleeding the clutch carefully may solve the problem. Or it may be that the Clutch Master Cylinder is also worn out. Often I just recommend replacing both to keep from having the hassle of one wearing out shortly after the other. The third possibility is that there is a problem with the clutch itself. An experienced technician can tell you pretty quickly where this problem lies. If you contact Your Mechanic, you can have a technician come out to your home or office to check out your Acura and recommend a fix

I can’t go into 4th or 5th gear and clutch does not engage after a recent clutch job, clutch release while in gear does nothing.
ANSWER : I would rule out the axle not being pushed all the way in. That would effect all speeds and gears. That you can engage gears other than 4th and 5th leads me to 2 m possibilities:
1. Shift linkage mis-adjusted.
2. Possible bent shifter fork internally.

If it feels like you can engage 4th and 5th with the engine OFF, then I would lean towards a clutch release issue.

Vehicle won’t go into gear when running, when turned off, vehicle will go into gear but won’t start. 1998 Ford Explorer
ANSWER : Hello – your clutch hydraulics are the problem here. Check the clutch hydraulics fluid level – and it may share the same reservoir as the brake master cylinder (both use brake fluid as the hydraulic medium). If fluid needs to be added, that means that probably the clutch slave cylinder is leaking – this might be visible as a clear, but bitter-smelling liquid on the ground under the engine. I recommend a clutch hydraulics inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Replaced clutch master and slave cylinder, but my car still won’t go into gear while running
ANSWER : If the hydraulics are working correctly, there are a couple of things that could be wrong with the clutch that would prevent it from releasing. Unfortunately, any of them will require removal of the transmission for repair.

At 191,000 miles, it could be that your pressure plate has failed and is not fully releasing, or it could be that the disk is severely worn and there is an accumulation of debris between the disk and the plate which would also keep it from releasing. Either of these would be corrected with a clutch replacement.

If you contact YourMechanic, they can send a technician to your home to evaluate your problem and help you figure out what to do next in order to avoid any unnecessary repairs.
