Overdrive Solenoid
The 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.
it is for normal driving it allows the transmission to work normally 2 will not let the transmission shift up from second gear and l will keep it in low gear
On an Ford automatic transmission it should be located on the transmission where the gear shift linkage connects. There is normally a 4 wire connector on it.
"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.
