Check of change fluid and filter--if this doesn't help it may be time for a rebuild
It sounds like a transmission problem rather than an engine problem.
The 1998 Buick Century shift solenoid is located on the top of the transmission. The shift solenoid can be access through the shifting console.
If the transmission won't shift out of first gear on a 1992 Buick Roadmaster, it could indicate the transmission gears are seized. It can also indicate a low fluid level.
Possibly a Clogged transmission filter. Change the fluid and filter.
Yes. Your best bet would be to find a donor car with an A/T. If not then, it may get very expensive. You will need a bell-housing, torque converter, transmission & mount, drive-shaft, and all the shift linkage. Of course you can go with a floor shift if you are not trying to keep it stock.
On top of the transmission where the shift cable is.
No
depends, what kind of trans is if, if its a 3speed then that's as far as it should go. Have the engine and trans computers checked for trouble codes. The 4 speed will not shift when the computer detects a problem and sets a code.
It should be on the transmission where the shift rod or cable attaches.
I have no idea what went wrong. Take it to a trans shop.
check fuses check for 12v supply at transmission-- wire @ 12 oclock on trans connector
Column shift? at the bottom of the steering column near the firewall Floor shift? Either under shift console or at side of transmission
