Location: Rochester, NY | Hi all.
Trying to find the CORRECT specs for adjusting the the Low/Reverse Band and also the Kickdown Band for my 1964 A-727 torqueflite transmission. I have a Chilton's that gives specs. for 1962 and 1963 torqueflight B (v8) but I want to make sure it's right. This is what it states:
Kickdown: Loosen lock nut and then tighten adjustment screw to 47-50 inch pounds then back off 2 full turns.
Low/Reverse: Loosen lock nut then tighten adjustment screw tighten 47-50 inch pounds then back off 3 full turns.
I've found videos which state tighten adjustment screw to 72 inch pounds but they differ in turns to back off... Not sure what to believe here. Anyone have good solid information that I can trust?
Thanks, Bob

Location: Rochester, NY | Well...I did some digging. Found my own answers to clear up some of the confusion I mentioned above. Turns out if one doesn't have some type of factory tool/adapter C-3705, spec is 47-50 in. lbs. If using an 8 point socket (which is a must to get onto square headed adjustment bolts) spec. is 72 in. lbs. This is good stuff, especially the lower link. When changing trans. fluid, I've always just dropped pan, fluid, replaced filter and reassembled. From what is stated in the the lower link, to keep a healthy transmission, sounds like it's vital that the bands should always be adjusted at this time too. Rear/low band adjustment is accessible when pan is removed. Kickdown (front) band is accessible from side of case.

The 72 in. lb. torque spec isn't all that critical, in the absence of an inch pound torque wrench I recommend tightening the adjuster just "snug" with a short (4" wrench) before backing out the specified number of turns. (2 turns out on both the front and rear on early 727's)
Technically, the turns out on the front band adjuster are dependent on the lever ratio (stamped in the lever); the higher the lever ratio the lower the number of turns out. This is why some have reverted to the "feeler gauge method", I. e. measuring the free play between the servo plunger and the lever...a 5/16" or 3/8" Allen wrench works as a feeler gauge with the wrench flats between the plunger and the lever. |

Location: Rochester, NY | Thanks Chizler...I was wondering about the different number of turns out...and the different lever ratios. Good...Now I know where to look for the lever ratio.
Thanks! Bob |
