adjusted the bands on my 904 before going to the track yesterday. made 2 passes @6.74 and 6.75 next 2 passes were 6.80 and 6.79. the 6.80 was in the heat but the 79 was about 12 degrees cooler. but the shift from 1st to second seemed to overlap each other. second to third were fine . is the band to tight or too loose ?

did it do it before the adjustment? if not then just back it off 1/8 to a 1/4 turn and see if it goes away, usually it is a 2-3 shift overlap/flare up problem, how is your tranny built? stock, rebuilt with good part's?

yes it a rebuild with good clutches and steels, did not do it before. so its too tight ?

I adjust my front band 72" lbs & 2 1/2 turns out, my double wrap rear is 72"lbs & 4 turns out.What are your bands adjusted to?

i dont have an inch # wrench ,just always snug up then back off 2 and ahalf. but snug is a relative term.

yep thats what im talking about, but i could have got carried away

My experience it does that when the band is too loose going into second
tighten 1/2 turn and try again. higher number kickdown levers 4.2 or 5.0
do not like to much play. 72 inch pounds 6 lbs is pretty tight so the wrist snug thing I go 1.5 turns back.

Does the valve body have LBA? What type of rear band, solid or double wrap?

If you have overlap on the 1-2 shift with a LBA valve body chances are the rear band is too tight, double wrap needs to be looser than 2 turns out.

turbo action trans brake valve body, has a solid band . so am i too loose or too tight you think ?

+2, too tight, back it off like mentioned about 1/4 turn.

thanks sooo much for the advice . im fixing it tommorow . you guys are the BOMB !
