SR-4 transmission/ clutch fork ?

I'll start by the symptom and then tell you what I think is going on.

I get a grinding noise only when shifting into Reverse. I find i have to throw it hard to get it into reverse.

I've also noticed the clutch pedal is pretty loose and doesn't activate the clutch until a good 1/3 of the pedal range.

I've also noticed the throwout lever is somewhat moveable ( grab it outside of the bellhousing and can push it in a little and rotate it a little).

I don't want to have to drop the tranny and check it out if I dont have to. Can anyone tell me if this stuff being somewhat loose could cause only my reverse to grind?

Note: When I move the throwout lever around it changes how easy I can put 1,2,3,4 gears in gear.

If this is the case how do I go about adjusting it?
thanks everyone. I hope I put this so its understandable.

Trust me.
Whatever you choose.
DO NOT REBUILD A SR-4

Is you Jeep a 4 cyl.? If so it has the hydraulic clutch set up and you may have air in your system or a failing master or slave cylinder. However, in my experience, reverse is the first to go when your SR-4 / T-4 gets out of spec. If this is the case, you will soon notice it trying to jump out of 2nd when you let off the gas, or not shifting smooth into 2nd. If your Jeep has the 258, then you may just have excessive wear in the clutch linkage.

It didn't work last time either.

Synchronizer ring for reverse is gone. Whether or not to rebuild the sr-4 depends on what you do/want to do with your jeep. If it is a relatively stock jeep that spends it's time on asphalt then just rebuild it IF you have the ability to do it yourself. The rebuild itself is fairly jeep and easy once it is out of the jeep. You can do it yourself for a couple hundred tops, as long as the gears themselves aren't toasted (unlikely). If you've got the resources to pull it yourself then you can do the rebuild. Piece of cake. I believe quadratech has all the parts. There is really nothing in there other than bearings and sychros. Take pictures, align things neatly as you remove them and take your time. Nothing to it.

Spook-
ok Ill replace the synchro on reverse. Everything else is working perfectly but I will check everything else out. I had the SR4 rebuilt prolly 2 years ago and it really hasnt been driven 100 miles on it. Im wondering if the transmission guys kept the orginial synchro.

Also, what about the clutch play? I've got the 258 so its all mechanical.

Im not seeing a specific synchronizer for reverse. I've seen them split up for 1 and 2 then 3 and 4.
I checked quadratec.com and jeep4x4center.com
Someone help me price one

You shouldn't even need my advice. I made that mistake once, but only once.
Find a different tranny like a T-4, a T-5 or a T-176. Even if they need a rebuild you'll have a better start point.

I dont have the money to buy a new tranny. Also, since your so hell bent at just saying dont do it please tell me why and what complications you encountered that why maybe they would help me. Just a thought though.

Hell bent, huh.
On second thought, you need to rebuild.
And "just a thought" from me... I'm done with you.
