Transmission cooler

[Larryfishes53]

My 2005 Mustang project is well underway. Should have the motor/auto tranny pulled this week and I’ll start on my Rock Solid Motorsports chromoly tube front end. I’d like to run a separate transmission cooler and by pass the radiator… Is this even possible or must integrate the radiator?

You can bypass it but why??? Just add another heat exchanger in line with the rest.

The 5R55S auto tranny in the 05-10 cars has it's own, separate auto tranny cooler. It resides between the eng cooler and the AC cooler. I installed the B+ M (aprx 9700 BTU) auto tranny cooler directly below the oem Ford auto tranny cooler, then plumbed them in series. I also installed a JDM catch can on the auto tranny. Also installed the PA performance deeper pan, which holds an extra 4 qts. Then used 100% synthetic ATF.

With my small Roush M90 blower, LT's, hi-flow catted H, FRPP twin 62mm TB, and 94 tune....stock, the auto tranny ATF would zoom up in temp, from 170 F to 200F, in mere seconds...on the hwy, with blower on, gas mashed. With the tranny mods, it now increases to just 171 F...and sometimes 172 F. Problem solved.

I removed the OEM cooler and replace it with a bigger one, i believe about 27,000 BTU's. Temp about 170F all the time. https://www.xtremediesel.com/xdp-x-tra-cool-direct-fit-transmission-oil-cooler-xd309. This is what it looks like.

Heat is the #1 killer of transmissions. Any type of cooler helps.
