98 CHevy Cavalier Shifting Problem

[Hobbydad]

Hello All!

Be nice I'm new!

I have a 1998 Z24 with automatic 4 speed transmission that was given to my son for his first car but has shifting problems. I am not so up on all of the computer cars. The problem is it seems to shift into 2nd but that's it. If I down down shift manually it will go back into 1st. Found that out by accident! It will not shift through all manually other that it shifting into 2nd as mentioned above. I ahve not checked the fluid yet because this is the transmission that doesn't have a dipstick. It is also kinda hard from to get it up off the ground and keep it level to check.

I also wanted to add, I have a check engine light on and dash says ETS Off.

Can someone give me some suggestions?

Thanks,
Hobbydad
