    Hi All,
    I'm working through my first TH350 transmission rebuild, and so far it has been going smoothly. I just installed the oil pump and am measuring the intermediate clutch clearance. The clarification is when I measure this clearance, I should not be looking to collapse the wavy washer at all - Correct?? I should be just looking to get the feeler gauge to drag a bit and that should be the clearance measurement. Thanks in advance for any input. Jim
     
  2. No, You don't have to, but the int. clutch piston usually has so much travel, it's never going to be a problem.
    I never use the the wave plate anyway. Just put another flat one in, and then shim out the pump piston.
    This being your first one, you probably didn't want to hear that. Just as well.
    How much clearance in the front half? Ought to worry more about that.
    What's the application?

    All I'm going to say is wait until Squirrel finds the thread and gives you a solid answer and follow that answer. Or Pm him and ask him.

    Thanks for the quick responses Guys. The application is simply a stock rebuild (came out of a '74 impala v8 car), no real hard use or racing in its future (going in my '55 belair survivor car). I installed the stock setup with one wavy washer, three steels, and three clutches. The Ron Sessions rebuild book says that the intermediate clutch clearance should be between 0.010 to 0.110. If I measure without compressing the wavy washer, I get about 0.075. If I start compressing the wavy washer, I go past 0.110. Thanks again for any input.
     
  6. Should be fine. Some of the light duty models have only two frictions but if they had three, that's what you want.
    As a general rule of thumb, you need to allow .010 per friction. More will usually be okay. Less, not so good!
    Let us know how it works.

    When measurement will be "without" compressing the wavy plate.
