2004' 300M: P1776 solenoid, replaced, now no shifting
hello, After 15 minutes of driving my 2004' 300M with 2.7l engine and (213.000km) I always got an error. P1776 Solenoid Switch Valve In LR Position and the car goes in limp mode.
So I ordered a new soleonoid block from usa.industries on ebay. I replaced it today, and filled in 4,5 liters ATF+4 after finishing.
also I disconnected the battery for 4 hours.
Now I can select every drive mode, but the car doesn't shift. I can rev the engine to 3000rpm and sometimes (<30%) the transmission does react then and shift.
I will test it tomorrow again after the fluid has set. I wouldn't say its too much or too low atf fluid, the oil stick is just before the first hot point.
the fact that the transmission sometimes react if I rev to 3000rpm, what is the purpose of this? somebody knows something about this?
there is no error code saved, so this is the only thing I hope that It could be too much or too low fluid.
