Re: Changing transmission fluid?



Thanks Herb.

Just to be sure I'm doing the right thing, should I be changing all
the fluid or just topping it off?  The car is a '63 Polara 500 with a
383 and automatic.  I have enough fluid that it shows on the stick
when cold, but idling in neutral drops below 'add a pint'.  It looks
healthy pink.  I bought it 8 months ago so I don't know the tranny
fluid history.  It's got 79,000 miles.

Is there a fluid I can safely add a pint of to top it off, or should I
replace it all?

Thanks again.
