I have a TTA with the 2004R transmission and here are the
symptoms; right before the car shifts into 2nd it feels like the
tranny starts to slip a little bit, and it also feels like the car
vibrates or shutters a little at this point also. It only acts this way
before it shifts and this is only at normal driving, if I floor it , it
seems to shift alright with no slippage. I adjusted the TV cable
and it did help the slipping a little bit, but not completely. The car
has 77,000 miles on it and I did notice that the tranny had a
sticker on it that said, original GM rebuilt transmission(TAF code),
so I don't know how many miles are on it, but it is not the factory
tranny obviously. Any suggestions on what the problem could be ?

Thanks

Servo issue or sticking 1-2 shift valve. Try to increase tv by a click or two and see if it gets better. Also drive car at 25 miles per hour. Manually shift 1-2-1-2-1-2-1-2-1-2 without lifting foot. Then go redrive and see what happens. A trans fluid service just before this is performed isn't a bad idea either.

Thanks Bruce, I'll try your suggestions tomorrow, I did change
the fluid/filter last month.
