Hello I have a 2000 chevy silverado stepside with a 4.8 and the nv3500 transmission. I just put in a new clutch, master cylinder, and internal slave clynder pre bleed system. And the clutch is really soft, and while it shifts it's far from smooth and hard to get into gear. I am wondering if i need to bleed the system even tho it was a pre bleed system. And if so how to go about doing so. I picked up a vac bleed kit as I also need to do my brakes od is there something I am missing that I should do after I installed it. Thanks I really dont want to remove the transmission again.

 

Short answer is yes.

 

b4 you rip it all out....see if a shop can pressure bleed it. vacuum bleeding isn't that great for getting air out.

 

Been there done that don’t waste your time with a vac or taking the trans back out make sure the hydraulic lines are tight reservoir is full get in it push the clutch to the floor side step it push the clutch to the floor side step it keep a check on the reservoir DO NOT LET IT SUCK AIR do this about 10 or 15 times and you will begin telling a difference

 

If you are talking about a manual transmission, and a hydraulic clutch? You changes the master cyl of the clutch?

Good news is bleed it like you do the brakes.

But you can't use a cheap tool. Gotta make sure you get a good vac on that thing.

Just try it again. But don't bother with cheap vac tools. Snap-On sells them, is one TRUST WORTHY maker. Don't even bother with anything that says "brake bleed". Make sure they say it will work on clutches. Get your specs all straight.

OR BETTER? Good news is bleed it like you do the brakes. Pump the clutch and have a friend. This may actually be more effective. Why? Because it's a tough system and it takes ALLOT of pressure / vaccum to clean it out - it's isn't as easy as brake bleeding. You really need two people it's not a job you can do alone.

Repeat as necessary.
