what does a slipping clutch feel like, I hear everyone say that their clutch is slipping. What does it feel like and when does it generally do it? I am sure mine has to be doing it with my TST comp on 9 and my stock 5speed with 138K on it.

It feels like your not going any faster even though your truck sounds like it is.

So, would the RPMs stay the same and motor rev? In 4th gear usually when I hit around 2k rpms my truck will kinda rev, rpms stay at 2k or fall slightly then they pop back up and I am off and running again, does this sound like clutch slipping?

Not sure what you mean by "RPMs stay the same and motor rev." Your rpms rise but you don't move any faster, almost like revving it in neutral. A clutch slipping is kinda like losing traction. Your tires start spinning faster but your not moving. FWIW, my brother has a TST Comp + Smarty on his truck and so far (8,000 miles) his stock clutch has held it.

a sliping clutch will cause the rpms to rise and the speed to slowly catch up if it ever will.

My tach jumps up, truck doesn't accelerate at all. If I let off too quick, which has happened, it'll bark the turbo. You know when the clutch is slipping, trust me.

An old timer once told me a good way to test your clutch.

Pull up to a tree, wall, building, or other immovable object, so your bumper is touching it.

Put transmission in 4th gear, let out the clutch.
If engine continues to run, you have a bad clutch, it is slipping.
If engine stalls, you have a good clutch.

I added this 3rd option myself:

If immovable object starts moving, you have a Cummins.

OK, I have had it slip a few times then, but I do have the problem not about my rpms dipping when I really get into it with my TST on 9 in 4th gear when my rpms "stall" or dip at 2k then rise back up, what could that be

is it just the tach dipping or do you actually feel the rpm drop?

Yea im pretty sure you will know when your clutch slips. My clutch does not slip until i get into 6th gear and lug it and im on a stock clutch.
