Right now the order of the day appears to be patience (at least for the weekend) and talk to Rockland on Monday to get there thoughts.

I was just on the phone with a very well versed friend/racer and his comments came around to fluid as well. He had asked if there I noticed anything with the fluid - which in fact I had - the fluid in the reservoir was slightly cloudier than the fluid in the brake reservoirs. He came to two possible reasons (naturally) - heat and water.

Going to go crazy sooner rather than later...

not that it pertains, but i have a spec stage 5 clutch in my 69, and it needed a .110 shim to give correct throw etc. that said i have the mcloed master, stock gm internal tb, and mine line is very close tot he header as well but i have it double wrapped in heat sleeve.
does it upshift fine in all conditions?
i would agree if it up shifts good(and has same tb throw everytime), it should down shift, unless there is an internal tranny issue(syncro etc)

Not sure if this will help, but Centerforce recommended that we use a tilton 400 series release bearing. The stroke was changed using a different Tilton face bearing to get the stroke correct for our application.

Good tech in the Tilton instruction manual

when i talked to mcleod, they were big on getting the proper engagement though the use of shims. since they sell three different thickness' of flywheels, it just complicates things even more.

+1 on the shifting. i dont see how the tob cares whether youre upshifting or downshifting. all it does is release the clutch???????????

I wish that I had actually received some help from McLeod but no such luck... the guy didn't want to listen to anything after "I have a problem"... darn

I know what you are saying about upshifting vs downshifting - at least in principal - but I need to explore all of the options...

Great info James!

The trans has ATF fluid in it? If you put 30W it will have problems shifting. I have to disagree about upshifting and downshifting, upshifting is easer to do with out the RPM "matched" Drive around and shift with out the clutch and see ow it acts. Maybe you will learn somthigng else that can lead you to the answer.

when the car is sitting can you tell any difference in upshifting or downshifting? And then when the car is running is it the same? When you engage the clutch all the way can you hear any audible differences?
