Here's why it's not a simple yes or no:
* Transmission type: Both years used different transmissions. You need to identify the *exact* transmission in *both* Blazers. Just because they're both Blazers doesn't mean they used the same transmission. A simple visual inspection might not be enough; you'll probably need to check the ID tag on the transmission itself.
* Engine compatibility: The transmission needs to be compatible with the engine. A transmission from a V6 might not work with a V8 engine, even if it's the same "type" of transmission. The torque converter and bellhousing are key aspects here.
* Year-specific differences: Even if the transmission types are the same, there *might* be minor internal differences or mounting points that could cause incompatibility.
In short: You need to identify the precise transmission type in each vehicle before determining compatibility. A professional mechanic specializing in transmissions is the best resource to confirm whether the swap is feasible and what modifications (if any) might be required. Simply looking at the year might lead to an incorrect conclusion.
