So here’s the deal. About a month ago, my car, a 1988 LTD Crown Vic (Automatic Transmission), started doing something strange. When I’m on the highway, and I go about 70 mph, everything is fine until I start releasing the gas pedal a little to make sure I don’t gain too much speed. When I ease off the pedal a little while going about 70, there’s a very strong vibration that can be felt and heard throughout the car. If I go faster than 70, for example 75mph, that vibration gets so much more stronger and louder. I have no idea what it could be. Could it be the transmission fluid? The fluid is very old and possibly very dirty (30yr old fluid is still in there, along with new fluid i’ve been adding)
If anyone has any pointers or suggestions, it’d help a lot.
The second problem I’m having is fairly new. It’s only happened 3 times the past week. What happened was if I were stopped, or going a very slow speed, like 5mph, when I’d give my car gas, it just wouldn’t go or pick up speed till after a few seconds. So far, this has only happened in the beginning of my journies; the first 5 minutes of driving.
I’m not sure if both these problems are related or not, but any help would be appreciated
