Hello everyone! I'm having a annoying problem with my volvo 740, as the title says the overdrive is constantly on and I can't turn it off. It makes the drive loud and slow.

Probably a B230F with an automatic box as the OP is from Ottawa. I would have expected the lock-up to reduce the engine revs and hence noise; or is it stuck in 2nd?
As the good Laird says, some more details on the mechanicals would be helpful.

If the lock-up clutch has seized in the on position, torque multiplication won't happen making it slower and likewise if the unidirectional clutch in the TC has seized although that can often have the effect of making it more lively and quieter.
