1997 Chevrolet Blazer power train problems

“97 BLAZER WITH ORIGINAL LOW MILES HAD ENGINE STOP BOTH ON AND OFF THE HIGHWAY SEVERAL TIMES BUT IT WOULD START BACK UP. IN JAN WHILE DRIVING DOWN THE HIGHWAY THE SERVICE ENGINE LIGHT CAME ON AND RPMS WENT UP. WE PULLED OFF AND FOUND THE TRANSMISSION WAS STUCK IN 3'RD GEAR. ALSO KEY WOULD NOT RELEASE TO REMOVE. ERRORS CAME UP P1860 P0785 AND P740 THAT REFER TO TRANSMISSION. THE PROBLEM WAS NOT TRANSMISSION BUT IGNITION SWITCH CONTACT BLOCK COMMONLY CALLED THE IGNITION SWITCH, IT IS THE CONTACT SECTION AND NOT THE KEY OR LOCK CYLINDER. THIS IGNITION SWITCH HAD ALREADY BEEN REPLACED ONCE. GM HAS A SERVICE BULLETIN #17006264 ON THE IGNITION SWITCH AND THIS APPEARS TO BE A BIG PROBLEM ACROSS MANY YEARS AND MODELS BUT NO RECALL WAS ISSUED. AN IGNITION SWITCH PROBLEM CAN CAUSE ENGINE TO DIE, LIGHTS TO GO OUT AND OTHER PROBLEMS BUT THE CONTACT FOR THE TRANSMISSION POWER SEEMS TO BE A COMMON FAILURE POINT. I REPLACED THE IGNITION SWITCH AND EVERYTHING WORKED FINE FOR ONE MONTH AND THEN THE PROBLEM RECURRED WITH ERRORS P1860 P0758 P0753 P0740 AND P0785. I TESTED THE IGNITION SWITCH POWER FROM RED/WHITE TO WHITE WIRE AND GOT NO POWER WHEN SWITCH WAS ON SO THE NEW SWITCH…”

“HAD TO REPLACE TRANSMISSION AT 140,000 MILES. SERVICING PER THE OWNER'S MANUAL WAS ALWAYS DONE, INCLUDING DEALERS RECOMMENDATIONS FOR TRANSMISSION FLUSH. TRANSMISSION SUDDENLY FAILED TO SHIFT TO 1ST GEAR, THEN FAILED TO SHIFT TO REVERSE SHORTLY AFTER THAT. 3RD PARTY REPAIR SHOP STATED TRANSMISSION WAS BEYOND ECONOMICAL REPAIR, SO REPLACED WITH 3RD PARTY TRANSMISSION TO THE TUNE OF $2800. *TR”

“INTERIOR METAL OF GEAR SHIFT CONNECTING IT TO THE STEERING COLUMN SNAPPED THIS DOES NOT ALLOW FOR SHIFTING TO ANY GEARS INCLUDING PARK. IN TURN, THE KEY CANNOT BE REMOVED FROM THE IGNITION AND PARKING BRAKE NEEDS USED TO PARK. *JB”
