T56 Install - Moves with clutch in - Lateral-g Forums

analyte · #1 10-15-2006, 12:51 PM

I finished up my T56 install yesterday and was going to take her on a trial run today. I'm using a LS1 T56 with a Mcleod 8710-10 SFI bell, clutch, and PP along with ATS OEM modified hydraulics.

The problems (probably related):

- I can't get it in gear with the car started
- If I kill the engine the tranny slides in gear easily, but when started the car creeps in first or reverse with the clutch pushed in

I can hear the throwout bearing pushing the PP fingers with the engine off and pushing the clutch so I know their is movement. I was in contact with Tyler throughout the ordeal so I know everything went in correctly and smoothly. I was told no adjustment shims were needed for anything, just slide the tranny in through the clutch/pp and hook up the hydraulics.

This is my first clutch install, but not first manual. I'm not sure what could be wrong. I'm going to grind the welds off my clutch stop and remove it in case I have it stopping it just before 15/16 inch.

Any other ideas if it's not the clutch stop?

Thanks,
Kerry

okay, I pulled the clutch stop out of the equation and it still wants to creep in gear with the clutch all the way in. It also will not go into gear with the engine running.

It seems I may be pulling the T56 to fix this. Any ideas on whay I'm looking for? I spent 3 days putting it in slowing checking everything twice so I'm not sure what I will be looking for that could be the problem.

I'll be watching this thread, because I am having the same problem plus a few more. I didn't feel like I was getting all of the air out of the system, so I ordered a new master from Tyler.

At one point, after I bled it, it would do exactly the same thing you describe.

There doesn't appear to be many lurking here tonight so I will call Tyler tomorrow and report back.

I put a post on LS1tech.com and it appears this is a common symptom of a clutch with air in it. I think Tyler bench bleeds everything before he sends it out, so I don't understand how air got in it.

Most likely, I will be going to get a Mityvac to bleed the system since I am by myself and don't have a second person around to work the clutch for me.

Does Tyler know which clutch you're using? Different clutches need different volumes from the master/slave/hydraulic TO to get the clutch disengaged. If there's not air in the system it sounds like the volume of the master is too small or there isn't enough plunger movement.

Jody,

I've talked to Tyler 2-4 times a week for the past few weeks. I am using the full recommended setup. The 12 in Mcleod clutch with Mcleod P/P using the Mcleod SFI bell. I got all of this info from ATS so that is why I went with this setup. I am new to the whole clutch thing, so I was looking for a recomendation.

I called again to verify that nothing needed to be checked with a dial, shimmed, etc. and was told it all slides in with no fuss, as it did. He never said it and I didn't ask, but I'm sure he's used this setup or he wouldn't have never recommended it.

Now if its not air in the lines, I am back to square one with no idea what's up. The T/O doesn't touch the fingers until right before it touches the floor, about 1/16-2/16 before clutch stops.
