Non-LS vs LS—what’s the difference?

Non-LS 4L60E uses a 298 mm converter and the traditional small-block/V6 bell pattern. LS-pattern units have a different bellhousing (with a top bolt hole) and typically use a 300 mm converter. Parts do not interchange without swap components.

What years/models does this 4L60E cover?

Many 1993–2000 GM RWD cars & light trucks with the non-LS 298 mm converter: C/K 1500, S-10/Sonoma, Blazer/Jimmy, Tahoe/Suburban, Astro/Safari, Caprice/Impala SS, and 1993–1997 Camaro/Firebird (LT1). Not for LS-based 5.3/6.0 trucks or 1998–2002 LS1 F-body without swap parts.

Is the converter included?

Yes—each package includes a matched 298 mm converter (billet and stall options available on performance tiers).

Do I need any programming or relearn?

We configure solenoids/valve body to your calibration. On 1996–2000 vehicles, perform a crank/PCM relearn after install for best results.

What about the cooler and lines?

Always flush or replace the cooler & lines to protect the new unit and maintain warranty coverage.

2WD vs 4WD—anything special?

Order the correct output/tailhousing configuration. If you’re changing setups (lift, tires, gears), tell us—we’ll match the package.

What’s the warranty?

Coverage is listed per tier—up to 6 Years / Unlimited Miles. Extend can continue protection after the Monster term.
