Default '02 Camry OD clunk

When I feather the gas on my '02 Camry SE 6 cyl auto (60k mi.) as I'm
drifting along in 35 - 45 mph traffic I experience a marked 'thud' as the
overdrive kicks out. Never happens if I turn the overdrive off. It seems to
happen more when the engine is cold. ATF is red and full - smells OK - what
else should I check?

Thanks for any help.

IE ... down_shifts from 4th(OD) to 3rd ...
semi-cold trany clutches bear the brunt of speeding up the semi-cold
engine


Your 'rating' as to smooth/moderate/harsh shift .
What symptoms when ...
.. accel positioned full off
.. " 'feathered', as you say
.. " full on, floored
and ... "at" =all= above when trany is a) warm, b) cold(<30 miles)
???

Cold tranys shift more harsher_er ... more abruptly.



I have a 94 I4 ... different trany ... 200k miles ...
I'd have to say 'smooth', all 3 above, warm trany ...
'some' moderate when =cold=.


> Never happens if I turn the overdrive off.


:-)
As "it" aughta 'be'.


>It seems to happen more when the engine is cold.

As "it" aughta 'be'.
Trany 'OD' shift in/out limited to warm trany.
When 'enabled', upon/at ?warm?, probably harsh at 1st.


>ATF is red and full - smells OK - what else should I check?


Not too sure if V6 oil_lvl=S= on a) trany & b) differential are
via different filler plugs ... check =both= ?? .
:-)

Whats in a 'word' ...
"thud" - a non-metalic sound ... perceptible jerk in car motion
"clunk" - kinda like the CV joints are bitching ... metalic sound

WRT 'remote' diagnostics ...
my aluminum 'helmut' helps , can almost read minds
but ...
terminology is critical.
Eskimos have 140+\- kindza 'snow' words .

Thanks for the reply. It is more of a thud than a clunk, and not the normal
downshift when cold. I'm the original owner and this is a new phenomena.
Hopefully the dealer can analyze the problem when I take it in.

Overdrive does not engage until motor is warm apx 120f. Something is
not right for it to "clunk"
