Power upgrades

[02_Tahoe]

I'm thinking about getting a tuner and other upgrades to increase the power but I didn't know if I needed to do anything to the transmission first before I add power, it's an automatic transmission. For diesel trucks I know you need to mess with the transmission first but I didn't know if it was the same way with a Tahoe

You dont need to mess with the transmission on either unless your planning on big upgrades that will add generous jump in power. Most handheld tuner will firm up and or adjust shift points based on the tune you choose. However unless your transmission has a bunch of miles on it already having a shift kit put in will make any performance gains easier on the trans and make the gains more noticeable. If you have a bunch of miles on the trans already have the trans analyzed by a trans shop before making any decisions on a shift kit.

The Trans has 225k miles on it, so I probably should have it looked at

Yup has the trans ever been serviced before?

I dont think so, I just bought it used about a month ago, but I'm 90% sure it hasn't

Then definitely have it checked out.

It feels good driving, I don't think it has any problems, but I definitely won't add much power without having it checked

Well basic bolt ons and probably a tune wont hurt dont have a shift kit or any trans work done without having its condition checked first.

Hypertech max energy is the tuner I have w a cold air intake,I bumped up each shift point by 200 rpm and increased the shift firmness by 50%. Woke my hoe right up just like new ..
