Alright so I totaled my 96 z28 in december and it also had a t56 but I did not have these problems.

The problems im having are this, the car stutters when im releasing the clutch until it gets going unless I release the clutch real fast. Also when I go to bang gears fast into second I get a grind even thoufh it still goes in. It does not do this when I shift liesurley like im regularly driving. I also have noticed that when I downshift I get a stutter vibration unless I rev match it upon downshift. Sort of irritating because I didnt notice any of this during the test drive.


Wondering what everyones opinions are, in a couple weeks ill probably replace the fluid as ive read that helps this sometimes, we shall see though.

Also like stated my t56 in ny 96 did none of this and was always smooth with a stock clutch even after the heads and cam (minus the occasional slipping on a hot day)

 

Anyone have any ideas?

 

maybe master is going out and fluid isn't letting clutch engage all the way? DOes the clutch stick at all during aggressive driving?

 

not that i have noticed, clutch pedal comes right out when i let off the clutch. I have read that the master cylinder going bad on these is common though, what are the tall tale signs of that? I have left it in gear sometimes though and forgo to turn it off and releaseed the clutch but pushed it back in and kept the car alive, when i've done that in the old camaro i had it never stayed alive and always died so maybe the clutch is stiking a little bit.

 

How are the motor/trans mounts? Any fluid leaks? What clutch is in the car?

 

I haven't noticed any leaks looking underneath, i've had a bad trans mount in my camaro and it didn't feel like this but i will check it next time it is warm out and i can get under the car. I just bought this car thursday so i haven't spent much time with it at all and am just trying to get a list of things to check when i finally am able to get under it.

I'm not sure what clutch is in the car, i would imagine a stock replacement clutch since most of the car is also stock.

 

with unknown history of the car, I would start with replacing as much of the fluid as you can with fresh. the LT1 sealed hydraulics are difficut to completely "flush" without disassembly and then bleeding can be frustrating.. Use something to get the fluid out of the resovoir and replace. Remove slave from bell housing and pump piston by hand with slave pointed down while a friend watches for any bubbles coming up.

Then jack the rear wheels up and put car on stands. start engine and in gear with clutch pushed all th eway in...and holding it there for a min or two...do the rear wheels start to turn? If so your hydraulics are losing presure, most likely a bad MC.

Your clutch may be worn and need replacing. Or it could be a "puc" type disc replacement clutch which tend to "chatter" on engagement, especially if slipped.

bleed your hydraulics first and confirm they are in good condition. If that does not resolve, you will have to pull tranny to inspect clutch and or tranny

 

thanks i'll have ot give that a try, was going to do fluids regardless, guess i should be clear this is an ls1 style car so are the fluids easier to do on them? I was just going to drain and re fill through the shifter which is what i read online, still need to do more research. I'm going to go ahead and probably say it is a clutch type disc, since when i let it out faster without slippage it seems to be fine no chatter only when i slip it a little like i use to with my z28 in traffic, guess i'll just have to get use to that. Or worse comes to worse i'll know the clutch is bad when it no longer works, most gears are fine and such just the second gear issue and i'm really hoping a fluid flush will take care of that guess i will see. Anyways i thank everyone for there help really dont want to put a new clutch into it yet since i'm trying to do headers this spring as well as a tune up with that. Ordered a lid for it already so my bolt ons are getting close to being done. Really excited to get into the ls1 game and learn more about ls1 engines, i miss the cleanliness of my z28 but this car will do just fine and all the tlc i'm going to have to put into it will be more rewarding when finished.

I wont drive the vehicle much except for inspection friday since weather is cold and crappy however once i get fluids changed i'll post back my results i suppose.

 

well i changed my fluids and only drove the car to the end of the road and back (new 315s are rubbing somewhere so i need to bfh some more didnt wanna drive far). The car felt like it shifted smoother however the second gear still grinded 2 out of 3 times i shifted fast, not sure if the new fluid needs to move around more or that one time i just didn't **** as fast as i thought i did. Oh well guess i'll be granny shifting into 2nd for a while, to much other things that need my attention.
