If you have done a compression check the next step is to take off valve cover and look.
i have a 1989 740 and mine is located on under the hood it the green 1 on the side next to the air filter
behind the fuses, below the radio, behind the lowest box in front of the shifter.
ATF can be added through the dip stick tube. Use a funnel!
underneath the intake between the block and lower intake mount
