Selespeed gears not initialising
Hello all, i need desperate help!!!!!
Im having such a bad week, first made redundant and now my gorgeous alfa is feeling down as well.
I have a selespeed, 156, 1999 model.
The gears do not initialise, and by that i mean that it wont go into any gear at all! On Monday when i used it, first gear and second gear were flashing, and then it stopped, so i thought nothing of it. Then on Tuesday, nothing at all, no gears, just a flashing light on the dash
The unit malfunction light is flashing on the dashboard and ive done some quick diagnostics using alfadiag.
The battery voltage is fine, at 12.72
Error codes present are P1746, P1747, P1748, indicating on the software that there is a fault on shift 1 2 and 3, these are the constant errors, the others i think are just bogus as i cleared them and they have not come back............ yet!!
The unit itself is full, at max with the tutela cs speed oil, so no problems there.
When the unit initialises ie the pump, it builds up pressure but then releases it again. It gets upto a max of between 25 and 32 bar, and then looses pressure. then it waits for over 10 seconds and then trys again with the same results indicating, i think, a pressure problem.
Maybe a sensor is faulty i dont know, i need help!!!!
