OD Fixed once and for all!
 

I just wanted to thank everyone for the help; my OD is back up and running. The tube that was plugged was the issue. I did a full system flush and replaced the thermostat with a stock Toyota unit and the OD is kicking in sooner than it has in a long time. I did buy a new temp sensor and I may swap it out just to swap it but so far the OD is working flawlessly! Thanks again I really appreciate it! :yotarock: :fart: :flush: I really love these new smilies!!! Priceless...

Another satisfied Yotatecher! Drive happy.
