[COLOR=yellowgreen]HEY, PEOPLE IS THE IGNITION SWITCH THAT BIG OF A PROBLEM ON THIS BLAZER. I HAVE READ THAT THE LINE VOLTAGE COULD MESS WITH THE TRANS NOT WORKING RIGHT. CAN ANYONE HELP ON THIS. I DID FIND A SERVICE BULLETIN ON REPLACING THE SWITCH IF TRAN STICKS IN THIRD GEAR. BUT, IS THIS THE REAL PROBLEM WITH THIS BLAZER? DRIVES FINE IN TOWN. PROBLEMS ON THE HIGHWAY. PLEASE HELP... THANKS!

my blazer does the same thing has no balls on the highway, the 4l60e is electronically controlled which means u may have to let off the pedal for it to shift if u have it floored

could do a simple search and if its a 97 most likely is.not speaking from personal problems just from reading the posts on here everyday.
