A 1998 Chevy Tahoe 4x4 also likely has a 4L60E.
Will the transmission work?
While both are 4L60E's, it's not a guaranteed swap. There are subtle differences between 4L60E transmissions across model years and even within the same year depending on engine and options. Things to consider:
* Bolt Pattern: While the bellhousing bolt pattern is *likely* the same, you need to verify this. A mismatched bolt pattern means the transmission won't even bolt to the engine.
* Transfer Case Output Shaft: The output shaft from the transmission that connects to the transfer case might have slight differences, requiring an adapter or making the swap incompatible.
* Computer Control: The transmission control is electronically managed. The 1995 and 1998 PCMs (Powertrain Control Modules) may not communicate correctly, leading to shifting issues or even damage. This is the biggest hurdle. A custom tune or wiring harness modifications might be needed.
* Internal Differences: Even if the external dimensions match, internal components like valve bodies can vary.
In short: While *possible*, swapping a 1995 4L60E into a 1998 Tahoe is not a straightforward swap. You'd need a mechanic experienced with these transmissions to assess compatibility before attempting it. Just because both are labeled 4L60E doesn't mean they're interchangeable. Professional advice is highly recommended.
