t-150 hard to put in gear

The T-150 in my CJ has been acting up. When at a light and I put it in neutral it is hard to get back into 1st. I can feather the clutch and get it to drop in or put it up in reverse then 1st and it does alright. It shifts great while driving no issues there, just doesn't want to go into 1st.

Do you have the "one inch" of free pedal at the top?

In other words, when you let off of the pedal, does it start engaging near the floor or closer to the top?

Is your gear juice topped off in the tranny and transfer case?

Has either been removed from the Jeep? How long ago?

Do you need help/ don't understand, with anything I have mentioned?

It has a hydraulic clutch...fluid is full. Oil level in tranny is full. Shifts just fine. Only have issues with going into first. It didnt always have this issue but it does now. If I ru n it up into reverse it will go into first just fine. Just tired of putting it in reverse at stop lights in order for it to go into first. I can cram it into first but dont really want to break anything at the moment.

Sounds like a nice quirk to have, and really not much effort to shift this way, but will keep those who do not know from driving it

Most likely time for a clutch job then. Clutch plate is probably getting too thin. If that is the case it will continue to gradually get worse.

Should probably try adjusting before tearing into things.

Help him out and tell him what specific adjustments he should make. Much better than a general suggestion.

He has a hydraulic slave setup so I'm not really sure of what he has. There should be an adjustment that regulates travel at the clutch fork. Another problem could be inadequate master cylinder piston travel which normally requires adjustment at the pedal pushrod.

That was my first suggestion. His reply gave me the impression that there is no adjustment. If there is adjustment available perhaps the slave cylinder rod length or ? then yes, by all means try adjusting it first.

If you run it up into reverse, don't you get grinding? Also, Check and see that no engine to bell housing or transmission to bell housing bolts have loosened.

No....no grinding putting it in reverse. The hydraulic clutch is all factory Jeep. I actually have a thread on here where I show it all. The clutch, throw out, and pressure plate are all less than 3 years old. Flywheel was also turned when I replaced everything. I have 2 other T-150s at the house. 1 in pieces ...for the last 10 years. Was going to rebuild it but never got around to it. Have the rebuild kit.....just picked up 2 other Jeeps and used the tranny from one of them. Another sitting in the garage that I am pretty sure works, just came out of the other CJ I parted out. Im wondering if I might have just tweaked a shift fork. Its almost like it catches on something. Like I said I can force it into 1st, but it takes more ooomph than I want to keep applying. It does not grind going into 1st at all.

I didn't think that 78 CJ's came with hydraulic clutches. If you're able to shift into reverse without grinding then your problem may not be with your clutch. Reverse on a T-150 is a sliding gear setup and if the clutch is dragging or not releasing, you would surely be grinding gears. Running it up into reverse effectively stops the transmission from spinning and allows you to shift into first. If it goes into second and high no problem whether at a stand still or moving, my initial thoughts are that you may have a first gear synchronizer problem. What oil are you using? Gear oils (most GL-5 lubes) formulated for limited slip rear ends can be too slippery for synchronizers to work properly.

In regards to your suggestion that you may have a tweaked shift fork. Could be but first and reverse use the same shift fork shifting the same synchro sleeve so probably not very likely since you are able to get first after shifting into reverse.
