This. This is THE answer to keeping a 6 in the truck. And an S-10 T5 from the 4.3 is easy to source. It's the V8 trans that is hard to get. Your truck will do EVERYTHING better with the T5. Tow, accelerate, cruise, MPG.

New cars make great power and they correct themselves for altitude and temperature, but what makes the biggest differences is the transmissions. You will absolute LOVE the T5.
