I haven't looked at the overdrive relay. But my impression is that relays are simple devices which are usually used to isolate a high voltage/amp circuit (that powers the item) from a low voltage/amp switching circuit.

Would another 12 volt high amp relay work? The light is low voltage so you could keep it in the switching circuit while the high draw circuit gets the overdrive.

As someone commented below, just because the dealer says it is NLA, doesn't mean it doesn't exist. I ran into this problem with my 1969 BMW back in the 80's and 90's. When the computer says the part is NLA by goodness there must be none anywhere. Good luck in your search.

hello
the white one will work in place of the orange but the shift light stays on.
try dave bartons website.
good luck

I do not think you use your shift lever too many times. From what I see in Art’s post the relay is entirely too complicated for what it ultimately does, which controls the solenoid and a reminder light.

A lot of stuff to latch on a relay, just so they can use a cheaper, less thought requiring push-on button switch. The relay is in there for current and so another switch can open the circuit for you.

Have you ever changed the other switch in the transmission that cancels the relay?

Someone makes another single pole, single throw, latching relay and probably better.

Ken, I believe the answer to your question is no. There is no substitute, that isn't a kluge, compromise, or hack.

I suggest you warm up your soldering pencil and repair it, or one of the previously replaced units. It won't be nearly as tedious as wedging LEDs into .100 grid perf board. Here's a map, in case you find you need to replace a dried-out electrolytic, and prefer to test it on your desk. I've included the others if you care to compare the designs. The 7764 is identical except the "OD ON" light is referenced to ground instead of the cluster's battery supply.







If that's impractical you could send it to me, and I'd fix it for you.

A man will pay $20 for a $10 item he needs. A woman will pay $10 for a $20 item that she doesn't need.

Aftermarket won't work for you? FCP has "1983-1984 Volvo 240 Overdrive Relay
$32.92"

(I think you have an AT - your ref to 3rd and kickdown.)
