I have a check engine light on and it is shifting a little late into 3rd gear at about 4000 rpm, when cold. Any suggestions or ideas as to what could be going on, if anything?

The cheap fix: Speed sensor connected to the Transmission Control Module (TCM). That screws up the engine control module and could throw you into limp home mode. Expensive fix: Transmission control module. Start with the speed sensor. Suggest that to your mechanic and get a second opinion before changing out the TCM. It's a simple plug and swap, but the module is expensive. I bought a spare on Ebay for my Volvo for $10. The TCU, I believe, lives under the right front kick panel, at least that's where it is on my 740.

Has anyone checked your "rev limiter" ? It is a sensor that will not allow you to "rev" your engine past a cetain RPM.
It is usually only "on" when you are in PARK, but it is something to consider.
Please let me know what you find.

The car has just clocked 185,000 miles
Its a great car but a pai at the moment, I've had a service including fuel fillter change added fuel cleaners to the deilsel all to no avail

Hi,
I think you should go to ur nearest Volvo service shop and have them check ur ECU for proper and accurate scanning of problem in the sensors and switches.
Hope that helps u out!
