Default 02 M3 transmission faults

Hi there folks. Working on helping get My brothers M3 back up and running. Prior to the engine issue (posted here: http://www.m3forum.net/m3forum/showthread.php?t=607843) the transmission would go into 1st gear, but when he tried move it would pop back into neutral.

With the new running issue we haven't been able to reset the codes and run again to get a fresh set of codes. below is everything INPA returned. looking through some of the faults are showing really low voltage which makes sense as the battery was shot. We have a new battery, just need to get he purring again. while we are working on that any ideas on what could be going on with the SMG?

We don't mind getting our hands dirty, looking for some advice homing in on the issue!

thanks

Default Re: 02 M3 transmission faults

swapped the battery, reset again and tall the codes went away other than a temp sensor need to road test to see if it holds, fingers crossed! just need to get the E38 together so we can move it!
