Will 99 blazer transmission fit in 99 gmc jimmy?

Yes, a transmission from a 1999 Chevrolet Blazer will typically fit a 1999 GMC Jimmy, as both vehicles share the same platform and many drivetrain components. However, it's essential to ensure that the specific transmission type (e.g., automatic or manual) matches and that any necessary adjustments or modifications are considered. Always verify compatibility based on engine size and other factors before proceeding with the swap.
