Hello,
I have a 1990 740 that has about 227,000 miles on it. Recently replaced the fuel pump and a week later, though it functions normally in the city, when I take the car onto the freeway, it will run in the overdrive gear instead of Drive.
I checked the relay behind the ashtray, it looks fine.
The mechanic where I usually take my car told me over the phone that it could be a kickback cable; however, when I looked in a Chilton service manual, there was no mention of a kickback cable anywhere.
If I change the transmission oil will that be a good start to eliminating my troubleshooting options? Can anyone explain to me the procedure for changing transmission oil? Is it just a matter of draining the fluid and replacing it?
Any other troubleshooting advise would help alot. Thanks.1990 740 Volvo Overdrive sticks, how do I change transmission fluid?
The overdrive relays are very problematic, as well as the kick-down cables. With the vehicle stopped you should be able to activate and deactivate the O/D relay, if it is sticking, try tapping on the relay while depressing the button, if it starts working, then the relay is bad. very very common!1990 740 Volvo Overdrive sticks, how do I change transmission fluid?

And that is the way it should work. Why do you see that as a problem? Once you are over a certain speed, it is supposed to shift into overdrive which also gives you better fuel economy.
