Re: 91 Suburban Issues
Just a thought, but if you're climbing in OD then the tranny is heating up way hot and the factory cooler integrated into the radiator doesn't help.
On my 4x4 we installed a 4 core radiator first, still got kinda hot, so I plumbed in a secondary cooler inline with the factory cooler that is in the radiator . . . now the truck runs much cooler pulling or climbing hills. I installed the cooler coming out of the tranny and then flowing into the factory unit to avoid overcooling in the winter. I thought all along it was my engine, turned out to be the tranny all along that was really overheating.
