Yeah it's an old car, so of course if there are transmissions issues that
shouldn't be a surprise due to its age.
It has about 150,000 miles on it, the behavior I've noticed is this.
It has just started "roaring" when it shifts into overdrive. Also, it's
reluctant to downshift at lower speeds even if I floor it. It appears I
would have to practically make it do so by using the "2-1" values after "D"
It has never done this before, it just started. I did add 1 quart of
transmission fluid (it was a tad low), but so far--about 3-4 miles after
having added it--the behavior remains.
Also, earlier on--BEFORE these behaviors cropped up--it sometimes would roll
downhill when in PARK because park wouldn't engage right away. Repeated
efforts in any given situation would cause it to engage, at which time all
was fine for that period. Lately, PARK works perfectly.
It upshifts fine as it goes through the gears, although during takeoff if I
hold down the pedal to try & make it STAY in gear longer it seems to want to
go ahead & shift early anyway. It does downshift normally when I slowdown to
make a turn, and then upshifts normally from there.
Is this a sign of impending transmission failure? Would a good idea be to go
to a transmission speciality shop and have them look at it to determine any
causes? If they uncover anything, would a replacement or rebuidling of the
transmission be likely? Also, (sorry if this is too many questions at once)
what would be a reasonable price for them to charge just to look at it to
see what's up?
