Vibrations have occurred since the day of purchase. Have not been corrected in 3 attempts at dealership. I requested from the chevrolet customer assistance that the regional service manager be involved in repair of my vehicle, chevrolet denied this service.
1999 Chevrolet Silverado transmission complaints
Page 4 of 4: complaints 71 to 98 of 98, newest first, as owners wrote them.
Onsumer is not satisfied with this vehicle. Dealership had vehicle for thirty days over two month period. Consumer heard a grinding noise underneath the hood . Front four wheel drive differential was replaced. Also, steering wheel had a lot of play, and was replaced with upper and lower shaft/ transmission wouldn't shift into second and third gears. Dealership reprogramed PCM, and the transmission still doesn't operate at all. The back window flew open from the third door.
Transmission does not shift out of 2nd gear when outside temperature is below 30 degrees.
Vehicle vibrates between 0 MPH to 22 MPH. More pronounced when towing trailer. Dealer and gm contacted, were advised is common problem, no fix available as of 12-6-99. Engineers working on problem.
Constant loud ticking noise from left side of engine/underbody. Only audible while truck is in gear and under accelleration. Suspect faulty catalytic converter or manifold to exhaust seals. If leaking, could pose health threat. Dealership and chevrolet advised. So far, response is that is the way it was designed. Noise is simply engine harmonics passing through tailpipe. I disagree
Transmission slips out of gear on occasions, on two occasions the key was removed and consumer was exiting vehicle at time of slippage.
Engine pings or has spark knock under acceleration or while towing a trailer. Also a spark knock when starting after being warmed up. Transmission will not stay in one gear while towing even on leavel road . Has had no luck with dealer . Dealer always states ( could not duplicate customers concern.) a g.m. Tech. Rep road tested this vehicle and stated all parameters are within factory specs.
After having in shop for 6 dys having the driveshaft replaced, 3 dys later, grinding and whining in rear end, differential bad(4th problem in 2.5 months with this truck!)
Excessive shimmy in the front end at approximately 60 to 65 MPH. Truck has been brought back to the dealership numerous times for repair, but no repair was available. We were told when a repair was available we would be called. To date, there is no repair available. I my opinion it is a hazardous situation due to loss of control, especially in wet weather. We have no idea if the problem is causing other front end damage. The tires have been rotated and balanced, front end aligned and then we brought it back to the dealership as per bulletin #99-03-002 (replaced both front hub bearing assemblies/ right and left rear spring eye bushings, and both rear shocks).
Driving on highway and drive shaft fell off. No warning of problem. Bolts remained in and the shaft just fell out. Tow truck driver said never seen anything like this. 3000 miles on vehicle, bought aug, 23 1999. Also, had vibration and noise from wind shield, had in shop twice for repair, ended up having to reseal the wind shield, dealer had done 3 simular trucks for the same thing.
Reprogramed pcmwith update.overdrive comes in at 51mph.fuel milage down to 12mpg.this is just a quick fix by chevy.
Exhaust: sounds like exhaust leak when accelerating from approx 4omph, dealer said it was smog pump. Drive shaft: clunking sound from rear of vehicle on take off, dealer said it was drive shaft and was normal. Transmission: shifting hard from 1st to 2nd and sometimes to 3rd. Windshield: clacking noise coming from windshield area at 50+MPH. Dealer said it was trim and replaced it 3 times, not fixed.
On 3 occasions, once around 1200 miles and twice at around 5500 miles, went to accelerate from a standstill, and the truck did not move. Engine revved, then slammed into gear, and then truck was able to move. No specific pattern to this, just random. Dealer "cannot duplicate the problem".
When the vehicle sits overnight the transmission whines for a few blocks, the tack does not show unusually high rpms.
Abs: while braking over semi-rough/rough surface, brakes seem to slip or disengage, causing extreme vibration. Transmission: while pulling trailer or accelerating uphill, excessive vibration occurs. Steering: while speeds 45 MPH+, moderate vibration in front-end and sterring column. Suspension: while tiurning wheels maximum left or right, or driving over uneven surfaces, hear a clicking noise in front-end. Rear window: latch does not securely tighten window causing excessive wind noise.
Vibration in drivetrain at speeds less than 45mph. Engine only runs 1,000-1,100 RPM's at speeds less than 45mph. Transmission shifts into 3rd at approx. 20mph and 4th at approx. 30mph. Engine feels like it is struggling at speeds less than 50mph. Two different dealerships stated there was a problem, but said that everything was electronic and nothing could be adjusted. A/c is not cooling sufficiently. It only cools on full cool with re-circulation and fan on high. Even then, air coming directly from center vent does not get below 48 degrees. I tested two other vehicles and both blew 40 and 42 degrees from center vent. Two different dealerships admitted there was a problem, but stated there was no fix. Driver-side outside mirror vibrates. Dealer replaced twice and both manufacurer and dealer refuse to replace again. Weather stripping along ouside bottom of both driver and passenger windows is defective. Dealer and manufacturer both refused to correct problem because other stock units look the same.
New vehicles need more testing before they are sold to the public.
While driving a t45mph a lot of vibrations occurs on passenger's side. The side view mirror would shake. Had vehicle in shop 9 days to correct problem. The tires & rims where checked, balanced & replaced. The driveshaft was also replaced. The problem has since returned.
While driving 20 MPH or above rear of the vehicle severely vibrates, cause unknown. The dealer replaced the tires/driveshaft and right and left axle and bearing, which has not corrected the problem. Please give any further details.
Drive train vibration problem is getting worse
Front ends shakes at 64mph/vibration in rear when you take off. Air sound when you press brakes. Jerks when you get to about 10mph. Been in shop 4 times with no repairs made at all.
Date of purchase: 10/14/1998. Check engine light appeared first day of pick up. Kightlinger motors put new part on the next week. December 28, 1998: took to dealer stating something wrong with front diff. Said nothing wrong. 1/17/99: front differential snapped, gear box broke. Would not warranty! Paid 3700 to fix.

Took to different dealer, replaced brakes and rotors. Front end needs replacing 7/3/99: no brakes-fluid leaks. *ak( dot number: 0000 tire size: 265r7516 )
Transmission is shifting hard when shifting from first to second gear while driving in low speed. Dealer can't determine the problem.
Transmission shifting hard form 1st to 2nd. Dealer replaced transmission assembly. New transmission shifted hard. Dealer reprogrammed truck. One week later, transmission started vibrating in 1st and 2nd gears. Dealer reprogrammed truck again. Now transmission not engaging in first gear untill RPM's are at or above 1500.
I took delivery of vehicle on 3-1-99. Noticed front end vibration at 65 MPH. Took vehicle back to dealer. I was told it was a goodyear tire problem. They replaced all tires. Problem remained as well as feeling a shaking in the steering on rough or bumpy roads. Took vehicle back to dealer. I was told that it was a drive shaft problem. Shims were placed in the driveshaft. Problem then became much worse. Vibration shook entire vehicle making steering difficult. Took vehicle back to dealer. Shims were removed. Gm knows about multiple problems and their only reply was "in 70 days we might have a fix". In 70 days the driveshaft might come up through the floor of my truck, too. Please look into these problems before someone is killed. Gm sure doesn't care! I have consulted three dealership service departments - two chevrolet and one gmc. They all admitted to having at least 6 or 7 trucks with these problems. Multiply that by the number of chevrolet and gmc dealerships in this country and you will see the magnitude of these problems. None of us can take on gm. Please help us. I might suggest that if gm can correct the problems, that they offer a free extended warrantee to all who were affected by these problems.
Other equipment; severe vibration that feels like body flexes between 65-75mph. I have slowed and pulled off onto the should fearing personal saftey. I have brought it to 2 dealerships for a total of 5 times, and spoken with gm customer service, as well as written a letter to chevrolet. They claim that it is a new "charateristic" of this year, no fix. Powertrain:transmission:automatic - it shifts into overdrive at about 37 MPH producing a growling sound, brought to two dealerships for a total of 5 times, no fix. Other equipment - clunk noise from front.
Since date of purchase, transmission has been vibrating and causing engine to feel like it is under stress/heavy load. Contacted dealer and another chev. Serv. Both advise chev. Knows of problem but does not know what it is or how to correct it. Contacted chev. Cust.serv. Total waste of time. They do not care. Simply state if chev. Tac says they are working on problem what do I care. They will fix it eventually. Problem is if they dont know what the problem is how can chev. Claim it is not a safety issue. Second problem- ABS brakes are activating on dry hard surface at speeds under 40 MPH. Dealer syays problem does not exist. Stated they called chev. Tac know nothing about break problems so there must not be one. Tried to say that I dont know how ABS works. Have had ABS for 15 years know it pretty well. It is definitely activating when is should not. It seems that chev. Is not concerned becasue truck was bought and paid for.
In cold weather transmission will not shift into 2-3 gear at approximatelly 21 MPH. Instead, it will not shift until it reaches 33 MPH. Cause unknown.
