Have you messed around with any vacuum lines lately? Typically a dancing idle is indicative of a vacuum leak. If you have a datalogger, hook it up at idle and see what your short term fuel trims are doing.
Also not sure why you mentioned the transmission because that has literally nothing to do with your issue?
