Hi my disco will only go in reverse,didl a stall test 3 days ago 2600, now engine revs freely with no drive, changed oil and filter no change, haukeye gave fault 1884 and po722,I was trying to find where on haukeye you can test the box solenoids but can not find it, on live data the only operation I seem to get is solenoid 2 which changes for reverse only, sv1 does not seem to do anything, can anyone give me a picture of the wiring plug on box to solenoids with what voltages and earth's, xzy switch seems to select each gear and displays on dash too, hhaukeye also sees the selected gear, cheers phil
 
P0722 means that the torque convertor is slipping and for 1884 the description is necessary cos there are 8 versions of it, no circuit test possible for that with hawkeye, as long as one solenoid works it means that there is feed to them cos the feed is common and the MVs are managed on the earth path... if you want to troubleshoot it yourself you have all the info in the attachments

Thanks for the info, rechecked gearbox oil it's gone burnt brown and smells burnt, everything seems to be working, does a stall test in reverse but not forward gears, removed gearbox today, think clutch pack gone, cheers phil
