Re: 98 blazer won't shift out of first gear until I let...
Could be throttle valve within the throttle body has gunked up and is catching the decent cable. Try changing tranny fluid & filter.
It can be the cause of many problems like that in transmissions.
Gives a false reading on the throttle position sensor causing irregular shifting.
