Since you are familiar with Fairfield could you give me your opinion. When I am In Vallejo and making my way up the grade toward Fairfield , the Bonny loses power in my opinion. I usually just put it in 3 or tap the brakes to get the converter unlocked and it then goes ok. Its worse when its warm and I have the AC on. Maybe this is normal .. Do you think I should be able to make it up that grade in overdrive and the TCC locked? Car has been running like this since I got it with 80k about 4 years ago, but seems to be getting worse.
