CASTECH CYLINDER HEADS ON 2001 THROUGH 2006 5.3L VORTEC ENGINES ARE POROUS AND ALLOW ANTIFREEZE TO SEAP INTO THE OIL. THIS IS A SAFETY CONCERN AS IT CAN DESTROY THE ENGINE (OIL DOESN'T LUBRICATE CORRECTLY, SLUDGE BUILDUP) AND LEAVE SOMEONE, AT THE LEAST, STRANDED, AT THE WORST, IT CAN CAUSE A HUGE ENGINE FIRE. GM HAS BEEN AWARE OF THIS SINCE 2007. THEY ISSUED A BULLETIN DESCRIBING THE PROBLEM AND WHAT NEEDS TO BE DONE TO FIX, BUT NO RECALL. TO FIX EITHER THE CYLINDER HEADS NEED TO BE REPLACED ($2500) OR THE ENTIRE ENGINE NEEDS TO BE REPLACED ($5500). MY VEHICLE IS A 2005 GMC SIERRA 1500 SLE. ALSO THE PROBLEM HAS BEEN CONFIRMED BY A LICENSED MECHANIC. THE FOLLOWING IS A LINK TO THE GM ISSUED BULLETIN. HTTP://WW2.JUSTANSWER.COM/UPLOADS/BLUEGORILLA/2008-12-05_142924_COOLANT_LOSS_5.3.PDF

CONCERNING GM 706 CASTECH CYLINDER HEADS/GM TSB 06-06-01-019B I HAVE A 2005 GMC SIERRA WHICH HAS SLOWLY BEEN LEAKING COOLANT FOR ABOUT 6 MONTHS. I HAVE HAD IT LOOKED AT AND THE DEALER INFORMED ME THAT I HAVE A 706 CASTECH CYLINDER HEAD THAT IS NOTORIOUS FOR CRACKING AND LEAKING. THE DEALER TOLD ME THERE WAS COOLANT INSIDE MY OIL AND RECOMMENDED REPLACING THE ENGINE. AS I HAVE BEGUN RESEARCHING THIS ISSUE I REALIZE THESE CYLINDER HEADS AFFECT MILLIONS OF GM VEHICLES AND LOYAL CUSTOMERS. GM HAS ISSUED A TSB AND ARE AWARE OF THE ISSUE AT HAND AND IN MY, AND MANY OTHER CUSTOMERS THIS SHOULD HAVE BEEN A RECALLED ITEM. I AM CALLING ON GM TO FIX THIS ISSUE/MISTAKE.

HELLO, MY COMPLAINT IS THAT GM PLACED AN UNDERSIZED TRANSMISSION (4L60E) IN THE POPULAR CREW CAB 1/2 TON TRUCKS AND I AM REQUESTING FOR NHTSA TO INVESTIGATE GM REGARDING THIS ISSUE AND MAKE A RECALL. MY TRUCK IS A 2005 GMC SIERRA SLE Z71 CREW CAB (K1500) WITH ONLY 76K+ MILES AND HAS THE 4L60/65E TRANSMISSION. THIS 4L60E TRANSMISSION IS ALSO USED IN GM TRUCKS COLORADO & CANYON AND WORKS GOOD FOR THESE SMALLER TRUCKS BUT IN THE LARGER SILVERADO & SIERRA CREW CABS THE TRANSMISSION WEARS OUR THE 3-4 CLUTCH PREMATURELY DUE TO THE WEIGHT OF THE TRUCK. THIS IS A BAD DESIGN AND GM HAS FIXED IT IN THE 2007+ CREW CAB TRUCKS BY USING A 6-SPEED TRANSMISSION INSTEAD OF THE PREVIOUS 4-SPEED. I WAS DRIVING ON THE HIGHWAY AND MY TRANSMISSION SLIPPED IN 4TH GEAR. I SHIFTED TO 3RD GEAR AND TRANSMISSION CONTINUED TO SLIP. THIS WAS DURING RUSH HOUR AND I WAS GOING 65 MPH. I HAD TO WAIT FOR TRAFFIC TO CLEAR ON THE RIGHT HAND SIDE SO I COULD GET TO THE SHOULDER WHILE I HAD SEVERAL CARS BEHIND ME WAITING. MY TRUCK COULD NO LONGER HOLD SPEEDS ABOVE 50 MPH WITHOUT SLIPPING THE TRANSMISSION. I COULD HAVE CAUSED AN ACCIDENT BECAUSE MY TRUCK COULD NOT ACCELERATE. THIS IS A POTENTIAL HAZARD. I HAD THE TRUCK TAKEN TO THE DEALER AND WAS TOLD I NEED A REBUILD AND THE MOST IT WOULD COST ME IS $3K TO FIX. I SAID NO THANKS AND PAID THE $45 DIAGNOSES FEE. I TOLD THEM WHY IF I DO NOT TOW WITH MY TRUCK AND DRIVE PASSIVE TO GET THE BEST MILEAGE AND SOME HOW MY TRANSMISSION NEEDS A REBUILD AT ONLY 76K MILES? THIS SHOULD NOT BE. I HAVE A 10 YEAR OLD CAR WITH 193K MILES AND IT HAS NEVER HAD A TRANSMISSION REBUILD. I HAVE CALLED GM AND THEY SAY THERE IS NO RECALL AND THERE IS NO TRANSMISSION PROBLEM BUT I DISAGREE. I ASKED THE DEALER TO PROVIDE ME WITH HOW MANY TRANSMISSION REBUILDS THEY HAVE DONE AND THEY SAY THEY DO NOT TRACK THIS INFORMATION. THIS IS OUTRAGEOUS BECAUSE THEY DO NOT GIVE GM ANY FEEDBACK ON HOW MANY REPAIRS THEY DO TO CARS OUT OF WARRANTY. *TR
