Transmission Noise

My 2 Chrysler vehicles, one with 40,000 miles and the other with 70,000
miles, make a slight but noticeable noise when one's foot is on the gas but
the noise goes away when the foot is off the gas. Is this normal and what is
the source of the noise. (Both get recommend changes of +4 fluid and
filters).

The engine?

 

Normal? For Chrysler it is. When I bought brand new a Dodge slant six,
225 cubic inch engine, I misread the manual. Duh. So I went too fast
during the 500 mile break-in period.

I made that transmission whine also. I sold car with 130,000 miles on
it. No work ever done on the transmission or engine. A drive shaft was
replaced under a warranty recall, thanks to a great dealer mechanic.
Only oil changes. It was used then as a cross-country touring car for a
visiting Dutch criminologist and his lovely wife.

My present Plymouth Voyager also whines.

You can do what I did. Had an excellent mechanic listen to it. He used
to build racing cars and said, yes it's there, but don't worry about
it. Do you have a really superb mechanic you can take your car to for a
quick listen to?

 

The problem on both cars became noticeable when I put on Goodyear
TripleTread tires; they failed to mask the transmission noise with road
noise. One of those "unintended consequences". My Chrysler dealer tells me
the noise in both cars is "normal". Perhaps Chrysler will address this when
they put out a new transmission.

I hope not, a new transmission design is needed like a lead balloon. Why
toss tried and true designs. You talk about putting out a new trans like
it's
as easy as putting out new fall colors in the dress lineup.

My 84 chevy trans whined right after I bought it, (used) I always thought it
sounded kind of cool. I was disappointed when the whine went
away after a trans fluid flush and a few years of hard driving on it. That
was about 2 years ago, and sadly the whine has shown no signs of coming
back.
