97 blazer tranny trouble

First step would be to check for codes and post back any code no.
Can you get it to take 3 or 4 gears?

no codes no it wont go into 3rd or 4th i do know it had always shifted kinda hard into 2nd but i had two other blazers that did the same so i dont know if it has anything to do with it or not thanks for the reply

I would get it on a engine/transmission capable scanner and see if it shows and thing in transmission data read out.
Watch for a and b solenoid switching and speed sensor data.
It should be setting a code if pcm/VCM/tcm is working.
If reverse is also gone you could have striped out gears on sun shell.
Also drop the transmission pan and look in there.
Good Luck MT
