Will a 02 4x4 blazer 4l60e fit 01 Tahoe?

While both the 2002 Blazer and 2001 Tahoe used the 4L60E transmission, it's not a guaranteed direct fit. There might be differences in the bellhousing, transmission mount locations, or even the length of the output shaft depending on the specific engine and options in each vehicle.

Before assuming compatibility, you must check the following:

* Engine compatibility: Ensure the transmission's bellhousing matches the engine in the 2001 Tahoe. Different engines may have different bolt patterns.

* Transmission mount locations: Compare the mounting points on the Blazer transmission to the mounting points on the Tahoe's frame. They need to align perfectly.

* Output shaft length: The length of the driveshaft must be compatible with the transmission. A slightly different length could lead to driveshaft vibrations or issues.

* Wiring harness: The transmission control module (TCM) wiring harness may need adjustments or modifications to work correctly with the Tahoe's system.

In short, while they *might* be compatible, it's risky to assume so. A thorough comparison of the transmissions and their respective mounting points is crucial. It's best to find a transmission specifically from a 2001 Tahoe, or consult a transmission specialist to verify compatibility before attempting the swap.
