Car is 2000 z28 with LS1

How do I install GM12570277 clutch master cylinder?

It is pre bled, so do I just disconnect the original line at transmission, and then plug in new assembly? I dont need to bleed anything further?

Any trick to the quick disconnect at the transmission?

Please spare me the comments about how OEM clutch master cylinder is POS and how I should have bought aftermarket. This one lasted 24yr + my car is stock powertrain. I had friends who had issues with aftermarket so I am not interested in hearing it.

Thanks for any advice or tips you can give me

 

You should still bleed it all the way, the fluid does have a life cycle and there's always a chance of introducing a bubble into the system. The install should be straightforward, but it is an absolute PITA to install it when your engine is in the way. You won't have a lot of room to manuever. Get help to install the u-bolt nuts on the inside of the car. I don't know about the quick disconnect, it's been a year since I removed the one in my SS, but I don't recall it being very difficult.

 

Can do - but you should consider the 'drill mod' while you have the part out. This will alleviate the stock part's shortcomings. If you search youtube for the drill mod, you will also see many videos on how to do the mod and also how to install the master cylinder! (Beware, not all have great ideas, so check out a few videos and you'll get an idea for what you should and should not do.)

Also, the vacuum bleed once everything is back together is key and takes some practice. Here is a good video for our cars:

You'll see all sorts of instructions on how to do this with screwdrivers, but it really messes up the quick disconnect. If you spend a few bucks to get the proper tool, you won't regret it! (They are really cheap.) Just search for 'T56 disconnect tool' and you'll see a bunch of designs: (I also recommend checking out youtube videos on this first!)
