Transmission clunking when downshifting 2-1

Hi Guys,
posting this here because I am thinking it could actually be related to a high idle and not a transmission/driveline issue. My car has a high idle and will run along at 20 mph easily with my foot completely off the gas. When I am coming to a stop it downshifts hard from 2-1 and I feel a clunk right before stopping. Is this due to the high/erratic idle? I just replaced the TPS and unfortunately that did not fix my issue. I checked the vacuum lines and all seem fine. None are dried out or broken. My next step is to replace all plugs and wires clean the TB and the IAC. Any other suggestions? Think if I fix my idle I will fix my clunk?
Thanks
