Is a Chevy Celebrity 2.8 and lumina 3.1 transmission comparable?

No, the transmissions in a Chevy Celebrity 2.8L and a Lumina 3.1L are not directly comparable and are generally not interchangeable. While both cars were produced by GM during overlapping periods, they used different transmissions depending on the year and specific model options.

The 2.8L V6 in the Celebrity often used a different transmission than the 3.1L V6 in the Lumina. Even if they happened to share a similar *type* of transmission (e.g., both automatics), the bellhousing bolt patterns (where the transmission connects to the engine), input shaft diameter, and other critical dimensions are unlikely to be compatible. Attempting to force an incompatible transmission could cause significant damage to both the transmission and the engine.
