If I will damage the transmission driving with the overdrive on, until repaired ASAP.

I will be forced to drive in 3rd gear until I can find why theoverdrive in my 86 240 DL Volvo is stuck in the ON position. The (automatic transmission) gear shift knob has the on off button foroverdrive. The yellow arrow light stay on. This just started an hourago, and I was forced to drive relatively slowly on the freeway to getto my mom's house. I will have to drive a distance to a repair shop etc. I will obviouslytry to stay below the red 60 mph (approx) line. I hear a click when trying to disengage the shift column OD button, soI don't know if is the overdrive relay. It is possible that a wire isfrayed in the engine area. My transmission is well cared for and seemsto work fine. 1986 240 DL (only) 89K miles. I do not need to use OD in my driving, I would be happy to disable itpermanently. I will try to find out what is wrong ASAP. But in the meantime, am I doing damage to the transmission ???

The OD on my 240 Turbo was out for about 18 months several years ago and guess what it did for my mileage? Absolutely nothing. It was still arouond 22 overall.

Mine dropped to about 17 mpg, from the 25 I normally got. That's almost entirely highway driving, cruising at 70-80 mph.

That's in line with what I observed when I lost the OD on my 240. Dropped from about 23 to just over 15 (mostly city, some hwy).
