Unless you have the upgraded hydraulics from SB there is no adjustment, thee is no way to adjust the factory clutch (that I know of).
If you do you loosen the jam nut on the collar and turn it to give you more or less play but it will also raise and lower the actual pedal.
I just took a wrench with me and adjusted it till it 'felt right'.

 

So it shifts better while driving or it will go into gear better now from a stop. Mine shifts smooth when i am moving, however sometimes when i am stopped and i have to put it in 2nd to get going, or have to put it into reverse, it doesnt always like to go into gear. Mind explaining the adjustment nut a little more, maybe i will take a look at mine, thanks

 

I didn't have a problem shifting while driving either. I would imagine it would have eventually gotten to that point if the shaft continued to get shorter (this created less pedal stroke). Get under there and take a look. You'll see the jam nut. All you have to do is break it loose and you can then turn the shaft. Like Fisherguy said, this will bring the pedal closer to the driver's side seat. However, I would imagine with the amount you need to adjust, this will be negligible. Mine was. Good luck and let us know how it turns out.

 

Thanks for the reply, i will take a look at it and see what i find. So the jam nut is right behind the clutch pedal? Just want to make sure i am looking in the right spot. Thanks

 

Yah, it's on the pushrod going to the master.
BTW, how'd that pump thing work out?

 

Well, much to my disbelief my hard shifting problem seems to have reappeared. Of course the first thing I checked was to see if the adjuster had worked it's way loose again... Not this time. So for kicks and giggles, I went ahead and ran the adjuster on out to get A LOT of pedal. I saw no improvement after doing so.

As a reminder, I have the Con OFE, and I also installed the upgraded hydraulics. The truck shifted smooth as silk today at lunch and even this afternoon. It's been shifting just fine. Went out this evening and that's when the problem popped back up. There's no fluid leaks anywhere. Tranny fluid was changed at 60k (truck now has 72k on it).

I'll give another update tomorrow after I drive to work. I'm concerned the slave/ master might be going south. Anybody had one of the upgraded hydraulic systems fail? For all intents and purposes, I've been driving like a granny lately too, not been ******* at all. What do you guys think?

 

Same deal this morning on the way to work. Very hard to engage 1st, 2nd, or reverse. I had to shift into 5th and then into 2nd and it went in much better. However, it still doesn't feel nearly as smooth as it has in the past - feels a bit catchy. I guess I'll be giving Peter a call today to see what's up.

 

That sounds more like how my dd acts. I would definately give Peter a call. Maybe your slave cylinder has an internal leak that you can't see?
Good luck
Will

 

Called and talked to Peter. He said it sounded like I was just barely not getting enough engagement from the hydraulics. He suggested that I remove the shim that is bolted between the bellhousing and the slave cylinder. After removing this, I will gain that extra stroke from the shim not being there. I'm going to take a look at it this afternoon. I'll report back the result.

 

No dice. I'm guessing the hydraulics are going south. We'll see what Peter says. I hope the tranny doesn't have to come back out!

 

So did you figure out what's going on with your truck? Did the adjustment fix it or are you still having problems like I am having now?

 

It was suggested to me that the input shaft bearing on the G56 might be going south. Evidently, this is a common problem for the G56, but I can't really find any pertinent info regarding this. Has anybody had or heard of input shaft bearing issues on these trannies? Do my symptoms sound like this could be a problem?

Inevitably, it looks like my tranny is going to have to come back out to inspect everything and to feel input shaft movement.

Any comments will be appreciated...

 

I did try the jam nut adjustment on the hydros, little to no improvement. I was running a double disc clutch. On another note, a guy i work with has an 04 nv5600 and i asked him how his shifted and he said that he has the same problems as well. He said sometimes it wont go in reverse and he has to pop it in to another gear, then i will go in reverse, same thing for when going into first gear.

 

I don't think this is a "problem"; rather, I think it is pretty much the nature of DD clutches. Granted, some are a little more difficult than others.

I've had a 3850 DD and a 3250 DD, and I always go to 5th and then into 2nd or 1st to start. I always go into 5th before reverse as well. No, it's not absolutely necessary all the time, but it sure helps things mesh a lot better.

When shifting, I always double clutch as well. It seems to be saving the synchros well, because I can still bark the tires between shifts when needed.
