I'm having a problem with my 2001 GC. When I drive up hills, its like it doesn't shift properly. It happens when I try to go faster too. When I step on the gas, it feels like a loss of power. I'll be driving up a hill at 55 and it slows down to 40, and I can't get it to go faster. I just had the fan relay replaced and they said something about the transmission getting ruined if the engine were to keep overheating(from the fan not working). it works now, and i'm wondering if that problem caused this problem?
