over the last few days, it seems like my transmission has gotten extremely hard to shift,,,,,with 1st and reverse gear being the hardest most of the time....
it always worse from a dead stop...once I'm moving , the gears seem to shift good going up in the gears and shift decent going down in gears....every now and then, it just feels like I'm pushing into a wall..I "giggle" the shifter and push harder than normal and it will finally pop into gear...it never tries to pop out of gear
I'm not sure my explanation will be exactly correct. Somebody will correct me if I'm wrong, but I think I have your answer. I have experienced the same thing - in numerous vehicles with a manual transmission.
I believe it's because if the synchros aren't meshed right when you're trying to get it into gear, you'll experience this. All you need to do is drop it into second gear (or another gear) and just bump the jeep forward the smallest amount, then try to drop it into first (or reverse). It should drop right into the gear you need.
let me guess. You just passed the 75,000 mark a short while back? I'm not sure if the 2.5 uses the same trans as my 4.0 did. I'd have to check, but with most pre '02 manuals (namely the lifted ones on bigger tires without a re-gear) the syncros get warn down. from the factory they have a beautiful taper on them. (cone, starts at about a 2" and widens to almost 3" over an length of 2.5") after your wrangler has seen some abuse, this collar shortens significantly. Essentially the small end of your syncro ends up being as big around as 2.75" do to the reduction in length.
I had to replace two sets of them in two separate YJ's. It'll shif ok if you rev match, and 2-3 of you gears will mesh fine if you row through them, the others will feel like there isn't even a gear there. It sucks, I know. I had a shop tell me it was my slave cylinder and clutch the first time it happened. I asked them to look at the syncros, when I picked it up they said that it was fixed and the syncros showed no wear, but the slave, master and clutch were all worn and had been replaced. I got back on the road and within 5 miles knew they had lied. when I got it back the second time, it came with a box of shredded syncros. They also cut a nice hole in my frame where they broke out a nut pocket... they're under new management now.
Once you have filled up the reservoir you should be set.
There will be no need to bleed the master/slave cylinder. Mostly because you can't. Starting in 1994 the master cylinder, lines, and slave cylinder are all one piece from the factory. Presealed and prefilled. No "user servicable parts" inside. Sucks
I am having the same problem. A mechanic buddy of mine explained that the clutch might not be being fully disengaged when you push in on the clutch pedal because you are missing the fluid that provides the power to the throwout bearing. Or, in my case because the clutch plate fingers have fatigued and are no longer strong enough push the pressure plate free of the clutch disk.
