problem #12

  • 55,000 miles


Defective odometer readings, gear indicators disappeared. The odometer reading disappeared, and the gear indicator disappeared on instrument cluster. I have no way to read my odometer, nor do I know what gear I am in, prnd21. Now I can accidently be in reverse and not even know it. This is an extremely dangerous situation, and there should be a recall on this. Mechanic charges $100 to fix, and also states they can insert any odometer reading that I would like to have. This should be illegal. I no longer have a valid odometer reading for my yearly inspections, or if I were to sell my vehicle. I could drive in 1st gear and burn up my transmission and shut down in the middle of the interstate and cause a serious accident or be run over for dead stopped on roads. My instrument panel has not had an accurate fuel guage reading in years, it comes and goes. I have been able to figure out gas usage by mileage, now that is no longer possible. I must fill up weekly just so I know I wont run out of gas. The car only has 55,000 original miles on it. This is just not right. I extremely upset about this and dont know how to get it fixed properly and covered from the dealerships. You should have a lifetime warranty on your odometer reading and knowing what gear you are in. Please advise and look forward to hearing from you concerning this very serious safety issue.

I have a 2000 Buick Century limited and the transmission harsh shift 1234, when hot and sometimes cold, I know that it needs a new 1234 up shift solenoid and to be inspected for failed parts etc, also the odometer, fuel gauge, and window regulators/motors have failed, the odometer is out and fuel gauge floats and windows have failed due to bad design of motors/regulators and my airbag light is on and each 4T65- E trans and many Buick trans like the one above has harsh shift and could cause damage and cause trans to fail. And the problems above will be found in many Buick Century and GM should fix the issues above for free it is a danger for the trans to fail and odometer/gear shift select to fail because most people will not know what gear they are in, and the trans could lock and cause a wreck or a huge injury or worst. And the trans 1234 up shift pressure control solenoid not keeping the right pressure could damage the trans, and even if the trans is bought used it still has this problem and is the same 4T65-E trans and GM needs to fix this for free there are many complaints and issue with the 2000 Buick Century, regals etc with this type of trans. And should be fixed right away before it becomes a costly repair or wreck! and the trans should be checked for any other failures. For free.

The contact owns a 2000 Buick Century. The contact stated that when the engine would become hot, the transmission would jump between gears. The failure occurred sporadically when traveling at any speed or when in any gear. The contact had to shut off and allow the engine to cool off in order to temporarily remedy the failure. The vehicle was repaired twice for the same failure. The dealer replaced the solenoid pressure valve to correct the failure. The failure mileage was 80,000 and the current mileage was 140,000.

The transmission on my 2000 Buick Century has a hard shift condition that was diagnosed at 2 different transmission shops as a pressure control solenoid failure that is very common with this car. One of the shops said the problem will reoccur even with replacement of the part unless a shift kit is installed.after researching this issue on line it becomes apparent that the shops are correct in their diagnosis. Why has this issue not been a recall!

  • Automatic transmission
  • 101,000 miles
The electronic odometer and automatic transmission display has gone completely dark. With indicator dark, the following are impossible to determine on the vehicle. A) automatic transmission indicator - for vehicles where the transmission shift lever is mounted on the steering column (like mine), other than counting the number of clicks of the transmission lever up or down, the vehicle operator has no idea if the vehicle is in drive, neutral or reverse. This is a major safety hazard because the vehicle operator may inadvertently leave the vehicle in neutral or in gear and not know it and leave the vehicle unattended. B) vehicle mileage -- there is no way to determine how many miles the vehicle has been driven. There are numerous instances on the internet describing this problem.

  • Automatic transmission

My car was experiencing an erratic, and harsh upshift when shifting from first, to second, and then to third gear.this problem was due to a faulty pressure control solenoid valve assembly. After investigating I found out that 17 different vehicles have this transmission with the same valve in it, that could have the same trouble.GM has a file on this problem, shtml file=901351
