clutch/transmission probs?

For the reverse problem, after stopping, try putting it into high gear, then into reverse. If I do that the 5 spd on my 84 Celica doesn't grind when going into reverse.

Is your clutch slipping at all?

Your clutch is not re-leaseing. Is it a hydraulic clutch? If so you may have a leak/air in the line. Make sure it's full of fluid and then bleed the air out. You may need a new slave cylinder. If its mechanical, then it needs adjusted - make the push rod longer.

How is the fluid in it? Do you have the right fluid in it?

If it is low, it can be bitchy to shift into 1st and rev.

Same if you have gotten water in it. That will make it bitchy too. The Jeep transmissions don't have a high water vent, just a stupid button vent so it is possible to get water in them.

Reverse always grinds a bit anyway if you don't put it into a forward gear first. Use 3rd or something first to settle down the tranny, then hit reverse.

Sounds like we have the same problem. I've got the 4 banger with the AX5 tranny. Mine is not fixed yet, but I'll tell you what I have thought about and maybe get some help myself:

Clutch slipping Clutch warped frozen pilot bearing slave cylinder low fluid air in the system

I tested the clutch slipping by turning off the engine and rolling down a hill while "playing" with the clutch. It seemed to me that the clutch had no play in it. It would either grab or not. So that kinda threw that theory out the window. My slave cylinder was replaced by the previous owner and also bled. So that should be fine. So my problem must be the pilot bearing????

Check some of these out

Jas> Hey all,

What you have (and the OP) is a clutch not releasing all the way, which is opposite of a slipping clutch. When your clutch starts slipping, you will know; The rpm's will race with no acceleration.

You either have low fluid and/or air in the system, or a bad slave/master cylinder. Just because the slave was replaced once, don't rule that out . Clutch warped, frozen pilot, not likely.

Hi Mike,

I have heard another way to alleviate reverse grind is to use a heavier weight tranny gear oil.

JimG

Being down a half quart of fluid or a tablespoon of water in the tranny oil will cause the same symptoms.

But then again, they are describing the 'normal' cold shifting pattern of any Jeep I have driven......

Warm them up and only reverse bitchs a bit.

Hey mike now that you say that, have done anything about the stupid button vent on top of tranny, when I was rerouting other vents I looked at that, tried pulling the top of to put a line on it, but it wouldn't come. I realise it is fairly high up, you'd have to be up to the door to get water in it, but water doesn't stay flat when you go through it, so even water up to frame might get in. Any solution? Greg

On my Borg Warner T5, the vent was just a plastic tube with the button on the end.

I took the top off the shifter and managed to pull the plastic stub tube out. I then used a piece of 5/16 steel gas line about 3" long for a hose nipple. The gas line fit exact and I had to tap it a bit with a hammer to get it in. I still used a little skim of JB weld just to make sure it wouldn't leak. I ran the tube up near the battery top.

I don't know about where the original poster wheels, but in our Canadian bush the beavers are always radically changing water levels and a crossing can go from a culvert under the road to 3' or 4' on top easily.

The last time we went camping, the beavers had raised the water up over my 33's on the main trail in. I hooked a back wheel off the edge and the water was over my tail lights. I commonly have crossed to the bottom of my headlights or 42" of standing water. If I stop, that water will rise all over. I have gotten a wet butt... How high is that button from the ground?

Mines the AX15, remember, I'm the one that everyone asks why I put an AX15 in. Anyway 81 CJ7 with 5" of lift and 33" BFGs, so don't know how high that is to vent, probably about level with floor, October on the west coast, I'm not going out to meassure. One thing about our weather, you can always count on rain and high wind for halloween.
