904 band adjustment........

904 band adjustment........ - 01/15/09 04:49 PM

What is the adjustment for the low reverse band on a 1976 slant six 904 transmission?

The book says 7 1/2 turns for a 1974-'76, and 3 1/4 turns for a 1968-'73.

What is the difference between the years on these bands? 7 1/2 seems an awful lot.

my 77 chry shop manual shows 7 turns backed off from 41 inch lbs(slant 6 w 904)for the low/reverse(internal)band as opposed to the usual figure of 72 inch lbs & 4 turns for a 318/360(1977) from 72 inch lbs. EDIT the kickdown (front) band is 2 turns(back from 72 inch lbs) for /6/318/360(2 & 4 bbl on the 360) in 1977

and as far as the bands, i beleive they changed the way the band is made.. but not positive..but im sure a trans guy will clear this up..

here are the specs from my manual as well. Some of the web sites i listed above (TCI) gives different specs depending on the type of band you are using.Maybe that will give you the info you need.

from my 72-79 manual, low and reverse band adj.Tighten the adjusting screw to 72 inch lbs. (8 Nm).


Fig. 2: Low-reverse band adjusting screw location



Back off the adjusting screw as follows:

A-727-2 turns

6 cly through 73 A-904T/A-999-3 1/4 turns, 74 and later41 in pounds then back off 7 turns

if it's an inch lb unit & accurate your good. My Sears beam one has worked good for me.

so when that said 74 and later

41 inch pounds back off 7 turns

that would cover an 84 904 lock-up as well?

any one with an 84 book?

7 turns just seems to be a lot

what happens if its not turned out that many times?

Keep in mind that there are two different style rear bands, the solid (single wrap) and the split (double wrap). The latter usually needs a looser adjustment (more turns out)
