Regearing manual 6 speed tranny

Anything is option but won't recoup the costs. The ultimate goal here is to spend less money. Spending $2000 to save $1000 doesn't satisfy what was asked. It sure makes one feel better.

With my truck I save about $5 per entire tank vs what a V6 uses in gas. Seems like it wasn't worth it until I see the $6000 at purchase I saved. Then it makes sense for me. Everyone will have a different opinion.

Definitely get your alignment and balancing in good order. Make sure tires are properly inflated and other maintenance kept up... Biggest way to save fuel tho, slow down.
