Just wrapped up one tedious install of one Ron Davis radiator and followed by one pcmforless tranny cooler (brake duct vers). Radiators nice but Jesus talk about a pita. Getting old one out was no easy feat nor was getting it in. But all that's water compared to plumbing the tranny. First the radiators tranny cooler fittings are to big so I had to bypass it all together so I'm thanking my lucky stars I had the pcmforless cooler i was debating on doing on a later time with me. Had to redo my fan mounts cause whole passenger side of the radiator was off compared to the stocker.you'd think for 670 bucks it would be perfect.
