SUBURBAN

1997 Chevrolet Silverado

I have a 97 Suburban with a 5.7 engine, 4x4,126, 00miles.
When I first start driving in the morning, I have no speedomator reading and it seems it will not shift out of first gear. The ABS light is also on. After a couple of blocks of driving, it will shift gears and I have a seep reading, The ABS light is still on.
I stop, turn off the engine, and restart. The ABS light is sometimes off and sometimes on and it seems to shift OK and I have speed readings. It works this way untill the next morning and we do it all over again. It seems to shift OK after it is good and warm. The ABS light is mostly off at this point. Sometimes when I brake, I hear the pulsating sound like the ABS is braking and I'm on dry hard road.
Is there any connection between the shifting and ABS?
Any suggestions about the shifting and speedomator?
Any idea on the ABS light sometimes on and other times off?

Could be the vehicle speed sensor-the computer uses it to determine speed and to command shfting solenoids for transmission to operate properly.
