Hey need some advice here on what to do. I just bought a 2008 Lexus is250 with 165k miles 3 weeks ago. Within the first week I replaced the water pump bcs it started leaking coolant, so got that fixed. Second week replaced the engine coolant temperature sensor bcs the check engine light came on. Now 2 days later I have the p2714 and p0761 codes popping up. The car is running perfectly fine, no problems shifting, doesn’t go into limp mode, doesn’t get stuck in a certain gear, but I’ve read other threads of what people have done to solve the problem. I’m not sure where to start if I should go ahead and change the solenoid, change the transmission fluid, or go ahead and do both at the same time. I’ve read other threads also saying it could be low voltage. The battery hasn’t been changed in 4 years, so I’m not sure if that could be an issue also. I really don’t know want it to be that the transmission is giving out but I think I’d be able to tell if it is or not. Any advice or recommendations help.
