6L PSD tranny cooler. Probably a tad on the overkill side for my new Troyer spec 4R75E that's going in the truck, but oh well. Hopefully the factory fluid temp switch actually does its job so the fluid gets above 100 degrees

 

All mounted and plumbed up with the new tranny hooked up.



Trans runs around 140-150 degrees on the highway, as monitored by a sender mounted inline with the "hot" line output. Gets up to around 160-170 when running it hard, and cools back down very quickly.
