1990 Honda Accord 4 speed overdrive tranny

I have a 1990 Honda Accord with 100,000
I noticed that when coming off the highway to a full stop, the tranny has slight "clunk" as it downshifts itself to 1st gear.
Also, when cold, it hesitates slightly until it grabs. This is only when cold, then goes away for the rest of the day.
I am wondering how these tranny's hold up and if anyone else has experienced symptoms similar to mine.
I called AAMCO and they said there are NO ADJUSTMENTS to make on these transmissions...
