700R/4 troubles , Need help !

Postby Killain [OP] » Aug 24 2014, 11:48pm

OK, I'm done with the restoring of my 1990 Silverado, 12871 Back on 12/8/2012 I had the 700R/4 in my truck starts to shutter and lag as if the clutch pack was having trouble. But it doesn't do it every time. It's a great shop, they have done work on all 3 of my cars and in business long, long time. My question to you How do I go about starting a discussion about this On/Off transmission problem ? I want to take some long trips, and since I already had the trans rebuilt but it now has this on / off problem. But I afraid to go anywhere being afraid of a permanent break down. :oops:

Is this happening in all gears or just certain ones?

UM, Just in first and it's a "lag" followed by a shudder like a clutch pack holding up or back , then pop it shifts and I don't know what it'll happen again. But it most likely will happen when the engine/powertrain is cold. Not sure if that helps. I did have the trans flushed out and Royal Purple MAX ATF install hoping it was fluid related but it still happens. Damn thing is I can't get it to do it on a constant basis ? Just frustrating !

I should mention that since I flushed out the dextron III and installed Royal Purple MAX ATF the bluntness or banging of the problem has lessened ? . . . So ? But also, I know nothing about transmissions. Thank you !
