Guys I really need experienced help! I bought a 1987 Buick Regal Ltd. Body and paint in great shape. Maybe I shouldn't have but I loved the car. I'm an old guy, we're allowed to reminice:-)) I put a tune up kit on it, but had an air leak in the intake manifold. I had the manifold pulled and new gaskets. It now runs great except, it doesn't want to upshift 'till it's doing 2000 rpm. It used to shift at about 1400 I think :-)) If I just lightly touch the gas it will run quite happily at 1900 without changing up unless I take my foot off the gas.The mechanick said it was nothing he did, even though it shifted great when I took it in. I did a transmission service, but no difference. Please help me guys, I'm retired and I don't have enough cash to take it to a transmission shop. I believe the transmission is a 204r? or
200r4? I think they only made them for a couple of years. The motor is a 305 v8. I couldn't see a modulator valve. I'm not entirely stupid about cars(But am getting that way) Please answer on the NG. Thanks in advance, Gerry.- posted
