Selespeed unable to change gears
I have a selespeed issue that I cannot find a replica of in the forums.
I was driving in 3rd gear and selected 4th, the screen showed forth and the engine just revved out so I selected 5th. I got a about 2 more minutes worth of driving in and then all my gear changes started failing. I pulled over and turned car off. Started back up and engaged 1st gear. I went through 2nd, 3rd and attempted 4th again and lost all gears again. I shut down and started up again, but this time I couldn't select any gears, no warning lights were showing, just flashing 'N' on screen, I just kept manipulating gear selector and managed to get into 1st again, 2nd and 3rd where I left it just to get home. Pulled in the drive way still in 3rd when it stopped. I cannot changed any gears now and the car is stuck in, well 3rd gear I believe. I put alfadiag on it, ran through all the actuators, selected the "return to neutral" which it fails to roll so im assuming, its not returning to neutral? I tried some calibrations, but just failed attempts. Rod length is at 28.3mm (I always check it every couple of months). Battery is strong showing just under 14v running and high 12's when on battery. System pressure is good with range between 45-53 and holds. I get about 3 gear change attempts per pump activation and pump activates both by opening door and key to MAR. I've tried holding gear lever in positive to throw into safe mode but I still cannot change gears. Selespeed oil is within limits and regularly checked, doesn't use oil at all.
Does anyone have a starting point for me to work on? I've cleaned the main sele connector and all the relays and they are working, to best of my knowledge.
No codes showing, just failed selespeed on dash.
If there are any selespeed techs out there it would be much appreciated.
