revving the engine

Is it true that revving the engine on an Automatic transmission in
either (N) or (P) will damage the transmission, torque converter, and
all other affiliated components?

Nope.

One exception - certain BMW cars with ZF automatics, after the
transmission has already engaged a driving gear after the car has been
started. This caused some amount of disgruntlement among Bimmer owners
living in states with mandatory emissions tests.

I'm glad to hear it.

I was driving my '02 Taurus today and decided to revv it up when
parked. The bitch has a revv limiter for 4,000 RPMs. I guess the
makers didn't want anyone toying with the engine for early wear and
tear.

Can the Revv limiter be removed or adjusted? Or is it all in the PCM
Computer?

I seriously doubt that that is the case, that is a pathetic redline. It
probably is a limiter only in neutral, to keep you from free-revving the
engine (which isn't particularly good for the *engine* mind you...)

If that *is* a factory set redline, there's probably not much in the way
of gains to be had by removing the limiter, very few cars continue to
make good power past their factory redline unless the engine is "worked"
a little for better breathing (cam swap, head porting, etc.)

It's a Taurus, who cares? Besides, those cars have bad problems with leaking
oil profusely all over the exhaust and the transmissions breaking. I know 5
people with Tauruses that have died with these problems. Why stress an
already weak design?

The rev limit in neutral and in gear can certainly be different. It was so
in the case of my former '91 MB 280E. In gear the limiter cut in at the red
line. In neutral it cut in at around 4000 RPM.
