What transmission does a 1998 Chevy Blazer have?
The 1998 Chevy Blazer most commonly used GM's four-speed automatic transmission, known as the 4L60-E.
Beyond that short answer, the question involves model differences, engine options, and how to verify the exact unit in a given vehicle. Here’s a detailed look at what transmissions were typically found in 1998 Blazers, how to identify yours, and what maintenance implications come with the 4L60-E family.
Transmission options by model and engine
In 1998, the Blazer lineup included both the compact S-10 Blazer and the full-size Blazer, with engine options that commonly paired with GM’s 4L60-E four-speed automatic. The 4L60-E was the standard and most widely used transmission in that year’s Blazer configurations.
- GM 4L60-E four-speed automatic transmission (electronic control), typically paired with the 4.3L V6 engine and also used with V8 configurations in many 1998 Blazer variants.
- Manual transmissions were not the common default in 1998 Blazers; the automatic 4L60-E was the expected option across most trims and markets.
The exact transmission can vary by body style (compact S-10 Blazer vs. full-size Blazer) and market, so verifying with the specific vehicle is recommended.
How to tell which transmission your 1998 Blazer has
To determine the exact transmission in your 1998 Blazer, use these steps:
- Check the transmission case for a stamped model number (look for 4L60-E) or a label under the hood or on the transmission itself.
- Consult the vehicle’s VIN, build sheet, or original window sticker to confirm the OE equipment list and factory specifications.
- Inspect the dipstick or fluid reservoir for the correct Dexron-type automatic transmission fluid recommendation used by GM in that era (DEXRON II/DEXRON III guidelines are typical for the 4L60-E period).
- If in doubt, have a trusted mechanic read the transmission controller data or reference the service history to confirm the installed unit.
Knowing the exact transmission helps with parts compatibility, fluid specifications, and maintenance planning, especially when sourcing replacements or diagnosing shifting issues.
Maintenance and care for the 4L60-E in a 1998 Blazer
The 4L60-E requires regular maintenance to ensure longevity. Use the correct Dexron-type automatic transmission fluid as specified in the owner's manual, and follow the recommended service intervals for fluid and filter changes. Common issues to watch for include hard or delayed shifts, slipping, or abnormal noises, which can indicate wear in the bands, clutch packs, solenoids, or a need for valve body service.
Summary
For most 1998 Chevrolet Blazer configurations, the predominant transmission was GM’s 4L60-E four-speed automatic. While the exact setup can vary between the compact S-10 Blazer and the full-size Blazer, the automatic was the standard choice across engines, with manual options being uncommon for that model year. Verify your specific vehicle via VIN/build sheet and inspect the transmission label to confirm the exact unit, then maintain it with the appropriate fluid and service schedule.
