How do i bleed the tranny lines in 1991 jeep manual transmission

The clutch should go to the floor =) But if it's not disengaging the clutch disk, there's definitely a problem between the pedal and the clutch disk. I'm guessing you have a hydraulic clutch?

This all depends if this is a hydraulic clutch or if its cable operated, you can only bleed hydraulic clutches, to bleed it you would bleed at the ******, you will see the bleeder screw on the slave cylinder that operates the clutch fork.

1. Fill master cylinder reservoir with DOT 3 brake fluid. Raise and support vehicle. Attach bleeder hose to bleeder screw on bleed line of slave cylinder. See Fig. 1 (attached in link) . Place other end of hose in glass container 1/2 full of brake fluid. Loosen bleeder screw while holding bleeder screw fitting.

2. Have an assistant depress clutch pedal to the floor. Tighten bleeder screw and release clutch pedal. Repeat bleeding procedure until fluid entering container is free of bubbles. DO NOT allow reservoir to run out of fluid during bleeding. Refill clutch master cylinder reservoir.

CAUTION: DO NOT allow bleed line to bend or flex when loosening
bleeder screw.

you can do this at the slave cylinder down at the transmission make sure the resvoir is full and bleed like you would brakes

U have what is called a hydraulic clutch, one of the hydraulic cylinders hs failed, there is a master and a slave cylinder. The most likely and most common cylinder to fail is the slave cylinder, this requires the transmission to be pulled out to replace it. the art is around $125.00, while the trans is out u might as well replace the clutch, the labor is about the same. Here is a picture of the part, let me know if u can see it.

There is a bleeder on the drivers side of the transmission follow the tube from the clutch master cylinder if you cannot find it. Pump the clutch up and hold it down then open the bleeder repeat till air is gone. May have to bleed again after driving a bit. If you want to bleed the clutch master cylinder run a tube from where the line goes into the cylinder and take the cap off and run the tube into the fluid (make sure its in the fluid) then pump the clutch slowly until no air bubbles. I just replaced my clutch master cylinder this is where the information comes from hope it helps you out!

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.

I would first bleed the tranny lines, if that doesnt work then your tranny is out and need to get it replaced. FYI with Jeep Wranglers, It is better to get a new transmission then to rebuild them

If replacing just the fluid, you should gravity bleed it by opening the valve at the side of the transmission where the line goes in to connect with the slave cylinder. Be sure to stand by and keep the tiny reservoir from going empty during bleeding, or you just make things worse. Assume you replaced parts. Is this right or wrong?

Or are you just trying to restore performance in a poorly operating system? Would help TONS to know these details, and how much you know about bleeding, etc. If you are trying to bleed a new slave cylinder, it can take 600 to 1800 pumps of the clutch pedal sometimes to clear it out manually. If you want instructions on how to bleed in with vacuum assistance, please post request comment to that effect.

Talk to you soon. TT

The clutch slave cylinder on this model is located inside the transmission bell housing. You would have to pull the tranny to see it.
Bleeding the slave cylinder is a fairly simple process.
Underneath the vehicle on the driver side you will see two hydraulic lines going into the transmission where the tranny connects to the engine. If you have trouble locating just follow the hydraulic line from the master cylinder on the firewall.
One of these lines is actually sticking out of the tranny and has a bleeder valve on the end.
You will need a 9/16 box end wrench and a 5/16 or 1/4 inch box end wrench and someone with you to press the clutch pedal while you are under the vehicle.

1. Top off the master cylinder with clean brake fluid. Also, MAKE SURE you keep the fluid level in the master cylinder topped off during this process. You may need to have a second helper to take care of this so you don't have to keep climbing out from underneath.

2.Hold the line with the 9/16 and loosen the bleeder valve a couple turns or until fluid begins to drain. Have someone SLOWLY depress the clutch pedal to the floor and hold it down to the floor until you tighten the bleeder valve back up. MAKE SURE YOU ARE OUT OF THE WAY OF THE SQUIRTING FLUID WHEN THE PEDAL IS DEPRESSED!!

3. Once you are sure the valve is tight, have them pump the clutch pedal a couple times . Repeat step two until the pedal has a full stroke.
