| Around the end of the warranty period, my truck started shifting into second gear hard after driving at highway speeds. toward the end of a 200 mile trip, the transmission failed and no longer has a second gear. the truck had 48,023 miles on it. i cannot determine for sure if the overdrive function is working, either. while failure did not cause an accident or personal injury, the potential was significant. this vehicle has only been used for personal transportation, not commercial purposes or hauling heavy loads. repairs will be costly. my research indicates repeat failures for this transmission. i am the second owner. i bought the truck from my mother after my father passed away. | |||

| Sunshell in transmission broken twice within 2 years, repair shop states heavy duty sunshell has been released to replace the inferior sunshell that was designed for the 1997 chevrolet s-10 pickup. repair shop states this is a common problem. repairs each time totalling in excess of $2,000.00. purchused vehicle from father at 13,000 miles. he had problems with transmission at 10,000 miles. serviced by love chevolet on dec. 1, 1998. | |||

| Got the truck at 48,400 miles. at 48,800 after driving at highway speed continuouly for about 25 minutes, my truck shifted very hard between first and second gear. the problem could be duplicated like clockwork. talked to both the local chevrolet dealer and chevrolet and neither would budge on assisting on the repair bill which came out to be $710. after reading about more complaint of the same nature on this and many more sites, i can't understand how chevrolet can get away with passing this cost on to the consumer. it's obvious there is a design flaw. *ak | |||

| Bought truck in october and have recently been experiencing extremely hard shifting from first into second gear. this is also accompanied by the service engine soon light. i spoke with a transmission specialist about this and he said it is a very common problem with these gm transmissions, he suggested replacing the valve body which he said is clearly defective from the factory in my opinion gm should issue a recall on these transmissions. *ts *jb ****dimsii ivoq entry posted after 12-12-02 cut over to artemis****760962 | |||

| At 40824amiles the car could not shift out of first geer and the service engine soon came on. i called the auto shop and they said to bring it in and that i could drive it until the light flashed. i took it in and had it repaired (which i have fought for the 200.00 deductable) at the time i questioned the fact that a transmission could go out so fast. ( i do not tow anything-it is a work car and take the kids to sports) two months to the day, i am having the exact problem with the car. everyone i talk with that has a 97 chevy blazer has a transmission problem.*ak | |||

| Started truck, put it in gear. no reverse,late shift into 2nd, no overdrive. dealer and 2 trans. shops say it's probably a broken reverse band or something similar. will find out when repairs are made. this should not happen at 48,000 miles. gm customer assistance says there's nothing they can do, me being 2nd owner and mileage being past the 3yr.36,000 mi. warranty.i believe gm should help me defray at least part of the cost. this is going to be expensive. a trans. failure shouldn't happen this soon under normal driving conditions. owners manual says fluid and filter don't even need changing at 50,000 mi. unless under severe conditions. i am thoroughly disgusted with this and with gm. thanks for your time. *ak | |||

| Transmission went at 72000 miles .i know that warranty expired,but it seems a new transmission should have lasted longer than that. i had two rebuilt transmissions put in in 60 days, and the engine check light still comes on, and the transmission needs to be worked on again. i have heard this was an ongoing problem with 1997 chevy trucks. *ak | |||

| I am unsure of the engine question. the information that i have is that it is a 4.3 liter v6. this problem has occured 3 times . it has occurred approximatly every 15000 miles. the first 2 times the transmission lines have been replaced under warranty. i have yet to get it replaced this time for i am still investigating my warranty coverage and this recent occurence. obviously, something in the structure of the vehicle or the line is defective. i have spoken to several mechanics ( dealer & private businesses), all say that this is a part that should never break, and are surprised that it has. any information you can provide would be extremely helpful and appreciated. thank you, t. muir. *ak | |||
