68RFE band adjustment?
As I am slightly OCD, our new to me truck is getting a once over. I need to know if the 68RFE has bands that need to be adjusted? I read the manual and they only reference the 48. I searched on here and have not really found anything. I am wondering about AAM diffs as well, do I put LS additive when doing a change? I have read yes and no.

The AAM diffs don't require slip additive. The LSD is not designed that way with clutch packs etc. Just good Synthetic oil.
As far as the Auto.. Not sure.

I read in one of the diesel mags that were are out on the newstands last month that the 68RFE does not have any bands to adjust. In fact they stated that if a repair shop told you that the bands on your 68RFE need adjusting; you should grab your keys and run from them all they are going to do is rub you blind.
I have just change my diff fluid in both axles and and they do not required any additives just use the proper synthetic fluid. I am running 75W-90 Amsoil.
Just my $0.02

The 68RFE doesn't have bands to adjust.
RE LS additive, I asked Redline if I should run their no LS additive GL-5, or their regular GL-5 (that contains LS additives).
They said that the AAM limited slip system does not have traditional clutching and does not require LS additive, but that the LS additive actually makes the oil slicker which wouldn't hurt anything and may reduce friction and heat in the gear contact area.
I've been running their regular GL5 gear oil (that contains LS additive) in the last two trucks with good results.
Any full synthetic GL-5 oil would probably be fine IMHO, whether it contains LS additive or not.

The synthetic oil doesn't require any additive and is slippery enough as is; just one reason why it is specified. It does a good job in lubrication of course too.
