Ok, from what I have read the fixes could be the adjustment band bolt/stud, replace servo unit seals, check for faulty fluid level, or rebuild the trans. My dipstick is currently reading right in between the lower max and min lines with the car running in neutral. All the other gears shift as usual. I know that the reverse is hydraulic while all the others are controlled by vacuum. Should I add above this dipstick max line and see what happens or try trans-x before adjusting the reverse band?
