I have an 88 formula with a 305 and automatic transmission. The problem is that when I accelerate with the gas pedal about half way down, there is a clunk noise- and another when either the transmission shifts or when I let off the gas.
This will also happen when I hold the brakes, and press the gas (not even enough for the tire to spin). When I do this with the brakes, and the hood is open, you can see the engine lift up from the back and lean forward.
This just started for the first time today. I am not sure if this would be a mount or what. But I also am not sure if the engine leaning forward is normal or not, because I never looked before. I am guessing that it isn't normal.
Has this happened to anybody before? Or if anybody has some ideas, I would really appreciate it.
Thanks,
Jeremy

 

sounds to me that you have a bad tranny mount ..... no its not normal for you motor to lean from front to back.... but change the mount and ill bet it will stop

 

ohhh yea till you get the new mount take it easy on it replace it asap

 

sounds like the tranny mount, buy a new rubber one
