after it slips into neutral you can hear a little clunk and your good to go again, I let right off until it goes back into gear again. when I put TCM in I had a good friend of mine and a well seasoned chrysler tech bring home chryslers scan tool and he did a quick learn on it, no more check engine light and no pending codes
fluid level is good, I always use the chrysler ATF +4 and napa transmission filter and gasket and change it myself (I'm 3 year apprentice)
started doing it about a week before it went into limp mode, now that its fixed it does it all the time
