No, a 1990 Chevy 4x4 truck transmission is generally
not interchangeable with a 1997 Tahoe transmission. While both are GM vehicles, there are significant differences between the transmissions used in those years and models. The bolt patterns, input/output shafts, and overall dimensions are likely different. Even if the same *type* of transmission (e.g., 700R4) was used in both, the internal components and even the external case could vary enough to prevent a direct swap.
You'd need to identify the *specific* transmission in each vehicle (e.g., 700R4, 4L60E, etc.) and then research compatibility using resources like transmission part numbers and cross-reference guides. Even then, a direct swap is unlikely without significant modifications.
