On feb 21st 2013 my transmission broke and it lost 2nd, 4th, and reverse, but was still drivable. i took it to a local independent transmission shop and they said it was a well-known problem. after doing extensive research i found that gm has known about this weak sun gear shell since at least 1998. the problem is that gm didn't remove the faulty parts from their inventory, although they updated the part sometime in2000 gm mixed the new parts in with the old so that their statistics would show that not all 4l60e transmissions failed. transmission rebuilders say you can only tell the faulty shell from the updated version by the serial number inside the faulty sun gear shell. many engineering accomplishments in transmissions have been made in the past two decades with materials and lubricants. there is absolutely no reason for such a massive gm transmission failure. what makes it so bad after the ten dollar part fails gm charges $3,000 for a rebuilt transmission. if the faulty sun gear shell was replaced before total failure the price is less than $1,000. i watched as my transmission was being rebuilt and there was no visible wear on any other parts. it looked like brand new except this faulty sun gear shell. if this problem is so widely known for so many years throughout the industry why wasn | |||

While driving my 02 silverado z71 (49900 miles) on the freeway at 65/75 mph, i noticed that the truck was slowing down and my foot was still on the gas pedal. the tachometer jumped to 6000-7000 rpm and i was going at 30-40 mph. my truck got towed to a chevy dealer and cost me 3600.00 to install a new/reman transmission. the dealer could not specify why the transmission failed. | |||

2002 chevy silverado 1500 - at 23,000 miles the transmission failed and was rebuilt/replaced at a gm dealership in pennsylvania - at 53,000 mile transmission failed and was replaced at a transmission shop due to being out of warrenty (that's a suprise) the trany shop found that the gm dealership had not even replaced all of the bolts in the transmission. the cost was $1500.00 plus a rental car during the repair process. i can see that this seems to be an ongoing problem with the transmission. my concern is that if my wife is driving and the transmission fails again. gm should have more than enough information to do a recall on the transmission. | |||

My vehicle has sustained two complete transmission failures within 50k miles of usage. the first failure occurred around 25k miles while trying to get out my driveway. the second failure occurred around 50k miles while traveling on a highway at 65 mph. luckily, i was able to make it into the breakdown without incident (only because of light traffic conditions). in both cases, the transmission was replaced under warranty service, so i don't have a complaint about that aspect. i do worry about the fact that two transmission failures occurring at around 25k miles apart suggests a pattern of failure. *nm | |||

Hello: last week my transmission gave out on my 2002 chevy silverado when i was going down the highway. after a detailed investigation, i have discovered that this is a common problem with this particular transmission, as they have corrected it on the 2003 models. i have 58,000 miles on my vehicle. the sun shell in the transmission strips out it's gears due to improper material used for the part. there is a technical bulletin on this matter. it cost me $2300 to have it fixed. please let me know what i can do. thanks so much. *jb | |||

I bought a 2002 chevy silverado in oct 2001. i have been the only owner and driver of this vehicle. my complaint is that since i have had this vehicle i have had the left rear differental axles seals and brake pads replaced 4 times and the right rear seal and brake pads once. the problem started when the vehicle had 15,682 miles , second time at 26,252, third time at 32,727 and the fourth time at 65,624. when i took the vehicle back for the third time i was told that the seals were fine and that i probably needed the pvc value, fuel and air filters changed. they changed everything and charged me for the work. within 3 weeks i went to another chevy dealer who stated that the axles did need replacing. they did the work that should have been done 3 weeks earlier. when i went to the first dealer about being reimbursed for work that should not have been done i got blown off. i now have paid over $500 for a reocciring problem which seems to be a defect. i have contacted general motors and even though they have talked to me i feel that i am getting nowhere. what is it going to take? me having an accident because my brakes get fluid leaked on them . i trailer my horse with this truck and god forbid anything happen when i am trailering. then are they going to listen and do something about this?*ak | |||

The rear-end in my 2002 chevrolet silverado has failed three times since i bought it. the truck now has almost sixty thousand miles on it but the problem first occured around 36,000. the first two repairs were made at cranberry motors in machias maine. the first was made without incident, but the second repair was not so easily delt with. after much debate, it was paid for by gm. now some nearly twenty thousand miles later, the rear-end went again. gm refused to pay for this repair and after another run-around i took my truck elsewhere. (to a mechanic that i knew was reliable and would charge me a fair price.) the rear-end has now been replaced for a third time but i believe that the stock rear-end components are over-priced and unreliable and would like compensation for the most recent repairs, but i know that it will be a fight all the way.*ak | |||

I bought a 2002 chevy silverado in oct 2001. i have been the only owner and driver of this vehicle. my complaint is that since i have had this vehicle i have had the left rear differental axles seals and brake pads replaced 4 times and the right rear seal and brake pads once. the problem started when the vehicle had 15,682 miles , second time at 26,252, third time at 32,727 and the fourth time at 65,624. when i took the vehicle back for the third time i was told that the seals were fine and that i probably needed the pvc value, fuel and air filters changed. they changed everything and charged me for the work. within 3 weeks i went to another chevy dealer who stated that the axles did need replacing. they did the work that should have been done 3 weeks earlier. when i went to the first dealer about being reimbursed for work that should not have been done i got blown off. i now have paid over $500 for a reocciring problem which seems to be a defect. i have contacted general motors and even though they have talked to me i feel that i am getting nowhere. what is it going to take? me having an accident because my brakes get fluid leaked on them . i trailer my horse with this truck and god forbid anything happen when i am trailering. then are they going to listen and do something about this?*ak | |||
