Could I Use A 2000 Impala Base Model Transmission in my 2000 Buick Century
My car has 180000 miles.
My car has an automatic transmission.
Unfortunately, no. The only other cars that will interchange with yours are the following: 2000 Chevy Lumina 3.1, 2000 Pontiac Grand Prix 3.1, and only year 2000 for other Buick Centurys. Other transmissions may look the same and bolt up physically, but may have different gear ratios and different electronics.
