Good to know! I have a temp gauge that I looked at closely this week so it definitely never overheated but it will feel good to have this wrapped upExcellent!
You actually don't want to drive around without lockup, when the TC locks up is when the cooler flow circuit goes fully open. Most people don't know that. So, you can burn up the trans without it.
Some shift kits or aftermarket valves will bypass this and be full flow all the time, but that's not needed.
