oil cooler question

thanks ahead of time.
I have an opportunity to purchase an OEM transmission cooler for my 09 Tacoma V6 but it looks lacking compared to others.
Would a Long Tru-Cool LPD Transmission Oil Cooler 4454 be a better choice and what would you recommend for hooking it up (bypass or not)?
I could not tell if the Tru-Cool had mounting brackets or how it is mounted.
Any help will certainly be appreciated. Also I live near Austin, Tx. and it is a little warm here......

 

With tow pkg I have the factory external cooler; imo stick with the OEM. I don't believe you'd need that much extra cooling. OEM would keep you in warranty restriction- and flow-wise.
Not supposed to disconnect the radiator cooler as that helps heat the tranny in cold months. So you'd loop it in at the battery side.

 

Thanks much for the input.
