Hi there,
Just inherited an '89 740 Turbo automatic and I'm having trouble getting the fourth gear in place when I depress the 4th gear button located at the side of the shift selector. I'd would usually depress it many times before the shift indicator light on the dash goes off and the tranny shifts into 4th gear. There's about a 1000 - 1200rpm difference at speeds of 100/kph so in terms of mileage I'd really like to get this solved. I do hear a faint clicking I've noticed everytime I depress the button but in doesn't always work.
Does anyone have a suggestion as to where I should start or diagnose?
Thanx,
Norbert
