Limp Home Mode

My 2000 9-5 occasionally goes into limp home mode while driving and both the check engine and check transmission lights come on. When I switch the car off then back on, it drives normal (comes out of LHM) but the lights are still on. After a few days, both the check engine and check transmission lights go off and the car runs fine for a few weeks/months until it happens again.
I used CarMD and pulled codes P1923 and P1701 the last time it happened. I think P1923 is "No Bus data from TCM". Didn't have any info on P1701. I've been told the TCM is approx $700, so I don't want to go that route unless I have to.
If anyone has any insight, it would be greatly appreciated.
