Engine options for the 2015 2500HD
The 2015 Silverado HD used two V8s, each with its own six-speed automatic. Use this table to identify yours. It is a reference, not a stock list.
| Engine | Type and transmission | Before you request a replacement |
|---|---|---|
| 6.0L Vortec V8 (L96, gas) | Gas V8 · 6L90 6-speed automatic | Match the RPO code (L96) on the glovebox label and the engine code. |
| 6.6L Duramax V8 (LML, diesel) | Turbodiesel V8 · Allison 1000 6-speed automatic | Ask which turbo, injection and emissions parts are included. |
The 2017 HD moved to the L5P Duramax, so a later diesel is not a direct swap. Sources: Chevrolet Silverado (Wikipedia); Duramax V8 engine (Wikipedia).
6.0 Vortec for fleet trucks
The gas V8 is common in fleet and plow trucks. Match the L96 code and confirm what accessories and wiring are attached.
