Bessie, Tobasco is sure dead on with that sugestion ,. also the oldest trans man in town is a good idea. Its easy to confuse the cast iron glide with the later aluminum ones but the best I remember the adj. on that band can be done externaly, also the cast iron glide doesn't have an oil pan.so almost all work on the inside requires dissambly. Adjustment of the band is a mater of losing a jam nut and runnig the center stud ddown and torquing with an inch lbs. torque wrench then backing off a given amount and set the jam nut. You need to get the specs from someone or maybe the oldest trans guy would do that for a reasonably price. If the oil looks and smells good you probably don't have major problems unless its a broken band
