should have the borg warner viscous on the lse. llts were on the 3.5 efi. if there's no selector for the diff lock it's the viscous box which is chain driven. not saying thats your problem,just the differences on the transfer box. they're very different to look at too,the viscous is sort of conical with ribs,the lt flat on the end if that makes sense.
