transmission? clutch pedal pressure?

Seems like a new week a new problem, I know nothing about transmissions so here's my problem, it's hard to go into first gear without flat out forcing it, but at the same time the clutch pedal seems to not have any pressure behind it anymore, you can push it down easily at least half way or more before it feels tight like it's actually engaging, tell me good news that it's not in the transmission itsself

start with bleeding the clutch system. next while running and in gear determine how much clutch pedal travel when you let off on the clutch until the clutch starts to engage. there should be 2 or 3 inches before it engages. try this and advise us.

Yea it feels a couple inches to engage, a week ago it had the same tension from the time you push the pedal all the way down now it's almost free til about half way down, say it needs fluid in the clutch cylinder , what kind does it use I've never had to do that before

These bad boys are getting to the limit of the lifespan of many of the OEM components. You should consider just replacing the clutch master cylinder. I just did mine at 220K miles and my symptoms were almost identical to yours. Along with a trans fluid change to Redline MTL, Its good to go now.

I haven't had time to get out and work on it yet but I may take the advice and replace the whole master cylinder

Fortunately, most of the components are relatively inexpensive and available at virtually every parts store.

Stay away from the generic parts for the hydraulic system, unless you enjoy replacing them on a regular basis.

The OEM parts were excellent, but dealers don't keep them any more. Luk brand is the best you can get these days.

Agreed. I'm pretty sure the generic brands are just NOS. The rubber is going to fail from age just like the one in your vehicle.

So bad news the leak isn't from the master cylinder or the slave, the only leak I see is from around the backside of the transmission and it's leaking down through the hole in the center of the skid plate , what does this mean

Check your transmission fluid level. Just open the fill port and stick your finger in there.

Also, rub the fluid that that is leaking between your fingers. Does it feel like oil or Does it feel warm and a little sticky despite the temperature?

It looks feels and smells like oil , the leak seems to be at the main back of the transmission , and would this have to do with the pedal losing pressure and the fluid disappearing

It sounds like you may have two problems, a leaking transmission or transfer case and a leaking clutch cylinder.

I believe your clutch hydraulic system comes as a full assembly in the 95. You buy the master cylinder, clutch hydraulic line, and slave cylinder all in one piece already filled with fluid and install it. Very easy job on the 95 which uses an external slave cylinder. This will take care of your weak clutch pedal.

Mopar ($270) http://www.quadratec.com/products/52007_05.htm
Sachs ($120) http://www.rockauto.com/catalog/more...266&cc=1185241

As far as the leak above the skid plate goes, you need to open the fill port (not the drain port) on your transmission and on your transfer case. Stick your finger inside and see if you feel fluid. If you don't, add more right away. If you do feel fluid, feel free to keep driving, but check very regularly to see how fast you are losing fluids.

Ok bled the system that took care of the loose clutch pedal , don't see any leaks on the whole system so hopefully that's that, now I don't want to sound too dumb here but transmissions are the one thing I'm in the dark about , can anyone tell me where the fill port on the transmission is , mine is the 4cyl by the way and if it is low how much should I add

I cant remember if it is drivers side or passenger side on the ax5, but there will be two plugs. The higher one is the fill port. You just fill it until it starts pouring out the fill hole. You may need to buy a hand pump to get new oil in (about $5).
