adjusting tranny shifts possible?
I've got an 06 GMC crew cab Z71 with the 5.3, auto od w/4.10 gears. It has about 140,000 miles on it. It's a real nice truck but it shifts kinda lazy so to speak. I've not been into one of these trans and haven't use a programmer before. My question is can the shift firmness and timing be altered by maybe a tech tool these days? Just thinking I might want to firm it up a bit possibly.
