The lower end (30,000 miles) is recommended if:
* You frequently tow heavy loads.
* You drive in stop-and-go traffic a lot.
* You often drive in extreme temperatures (very hot or very cold).
* You use your vehicle for off-road driving.
The higher end (100,000 miles) might be acceptable if:
* You primarily drive on highways under normal conditions.
* You keep your vehicle well-maintained.
Crucially, consult your owner's manual. This is the *most* important source of information regarding the recommended service interval for your specific vehicle. GM's recommendations may vary depending on the exact transmission your Tahoe has.
Ignoring transmission service can lead to costly repairs down the line, so it's best to err on the side of caution. If you're unsure when the last service was performed, it's better to get it serviced sooner rather than later. A qualified mechanic can also inspect your transmission fluid and determine if a service is needed based on its condition.
