Trans pan gasket..sealer or no sealer?? and other trans ???

OK gang, heres the latest on my project. After much reading of this thread and a call from a reputable trans friend, I am going with your recommendations regarding the gasket. A light coat of copperseal brush on between the pan and the gasket, just to keep it in place while I put it on. Next, I bought 2 gallons of Dextron fluid and am satisfied that it will be sufficient. The information from my trans friend and a 1971 service manual regarding band adjustment is this... Tighten the low/reverse band (the one inside the pan) to 72 in/lbs., then back off the adjustment 4 turns for 318 models, then torque the locknut 35 ft/lbs...the 2-3 shift band on the outside is also adjusted to 72 in/lbs then backed off 2 turnsand the locknut is torqued to 27 ft/lbs.

As for the squealing noise...the noise happened to me twice, once when I was putting it up on the trailer and the nose was up but the rear wheels were not yet on the ramp and I gave it some gas to get it up. The second time it happened I was taking it on it's maiden voyage around my block and hit the gas kinda hard to see if it would squeal again, which it did. Under light acceleration it does not do it, and I haven't had a chance to check it again. I checked the belts and they appear tight, and they are also new. The general consensus is that it is not the trans making this noise and that a trans would not make a noise such as this, so as soon as I get the trans buttoned back up I am going for another ride and a thorough check of this noise. I will report back as soon as the ride is taken. Thanks again for all your input everybody, it sure helps alot to be able to concur with so many people and come up with a plan that works!!! Geof
