I have an automatic 1992 740 Wagon. I got it in 2003 and it ran very reliably until then end of last year -- when it started stalling and needed a new head gasket. I did this myself with much help from Volvo sites like this one and discovered that despite it's age the car is still quite solid (no sign of rust) and in decent condition. So I'd like to keep it running properly.
The car has most of the typical issues (erratic speedometer). One issue it's always had however, is a tendency to change gears only at higher revs (e.g. >3500 rpm). I have inspected the kickdown cable running from the throttle. Close to the adjustment nuts, the plastic sheath is bent exposing the metal cable. The cable here looks pretty frayed and was sticking badly. I tried to snip off the frayed bits and lubricated it by trying to discharge a couple of syringes of ATF down toward the transmission.
Now the kickdown cable is not sticking but I can't seem to adjust it to make the gear changes happen at lower revs / more smoothly.
1) Will these issues likely be addressed by installing a new kickdown cable? Or should I be looking elsewhere (e.g. the transmission itself, or possible the transmission relay)?
2) Is the kickdown cable installation relatively easy to do? / worth doing in this case? / any tricks or gotchas the inexperienced DIYer should be aware of?
Thanks,
Rob
