thanks guys, ill fill the gearbox oil up tonight........battery voltage is fine btw (12.45v), when i turn the key to MAR, it bleeps a few times 'n' flashes on the dash and so does the selespeed warning light, the engine wont turn over, as if it thinks its in gear. So my theory is, I definitely left it in neutral when i turned the car off last time and the new gearbox which i fitted, I was told the new gearbox was also left in neutral when removed, plus fitting my original actuator back on the new gear box went on in the same position as when removed (i.e didn't have to move the selector shaft at all). so the actuator has probably recognised that something is different, perhaps it cannot tell what gear its in? nothing surprising as I cannot run EOL calibration.
When i removed the actuator from my gearbox, I did disconnect a few of the sensor plugs to gain access etc, plus the car had been standing for a month or 2, perhaps it lost its memory anyway.
I noticed on alfa diag there are a few options under the calibration routines, one of them (cant remember the exact terminology) said roughly 'new actuator install' or something perhaps i need to try that option.
Ill double check the pump pressure tonight also, as I heard the pump prime for the same time period as before but that doesn't necessarily mean it was able to reach pressure.
I had drained all the selespeed fluid upon removal, as this was all new to me I removed the back plate by mistake not knowing how to remove the actuator.
When I filled the fluid back up in the selespeed reservoir, I filled to the correct position then opened up the bleed screw, fluid come out straight away, so I screwed it back in, assuming that it as its gravity fed, but thinking about it that doesn't mean that there isn't any air still in the system.
What is the correct way to bleed the selespeed system?
