How to change shift points?

[Ruger_556]

How does one change the shift points in a '94 4L60E? I want to move the 3-4 shift so it holds longer (IE: If I put my foot down I want it to stay in 3rd until I get to the top of the hill)

Details Is it as simple as buying a chip or do I need to write mine own to do it? If I can just buy a chip which brand?

No, it needs to be written. You can learn to do it or have someone else do it. Head over to gearhead efi

94 will be a chip.

You can either have a "tuner" do it for you or you can learn to do it yourself for about 200 bucks in hardware from Moates.net

Just changing shift points is easy peasy....

Check into the aldldroid. You can do some running on there.

tunes are customdone for your specification, chips are garbage in my opinion. learn to do it yourslef and itll be time well spent because then you can do H/C/I swaps and retune your truck in a moments notice, no waiting on people etc etc.
