Part number for transmission

[dboyw]

I'm looking for the part number for the trans cooler bypass valve. I don't think mine is bad, but with 145,000 miles and I am finally going to install a tru-cool cooler, I wanted to replace just because. Also, what is the best way to clean the factory cooler? I was planing to remove, spray with brake cleaner and blow with air. OK or not?

Thanks
