∙ 14y agoThe transmission shift solenoid on a Volvo s80 is located in the gearbox. It is inside the side cover and not easy to reach.
VERY CAREFULLY.
Has recent work been performed?
the transmission could be going out or slipping or your transmission fluid could be low
They normally don't. I suggest you have your transmission & filter changed.
ECT is for towing, you activate ECT so your transmission doesn't shift into a higher gear until it reaches a higher minimum rpm. This will create less load on the entire drive train as a whole.
Right now, it seems like a toss up between the Volvo I-Shift and the Allison TC10.
A common problem with alot of Volvo's is the Overdrive. Basically the high gear. If it wont shift into high gear it means that the "Overdrive" is activated and won't shift into high gear. You need to see if there is a little upwards pointing arrow on your Dashboard Cluster. If there is then you need to replace your Overdrive Solenoid.
The tcc solenoid, and both shift solenoids are located in the SIDE pan of the transmission. Towards the front of the car, the tcc solenoid is the lowest one, or closest to the ground.
"s" for sport "e" for economy and "w" for winter depending on how you want the transmission to shift for the type of driving you do.
This button is for winter mode. The transmission will start in 3rd gear thus reducing wheel spin when starting from a stop in slippery conditions.
Vacuum on an automatic transmission normally controls shift timing and would not effect downshifting (normally). Shifting is normally caused by internal fluid pressure in the valve body, with WOT control to over-ride shift points. Check the shift cable and make sure it is properly adjusted, if that is not it then the problem is internal to the valve body of the transmission.
