New Gears.... now what???
I posted another thread on swapping my 3.23 gears for 4.10 on my RWD 2005 GMC Sierra 1500 with the 5.3L and 4 speed auto (4L60e). I took the truck in this morning and picked it up about 2 hours ago...

All you need is A Hypertech Programmer, It will fix your Speedo and Abs light issue, and will give you slightly more power, I have a 2000 Silverado that I went with 4:56's because of bigger tires, no problems with the Hypertech works perfect..
I'm going with a custom tune done on a dyno for towing and it will address all of the issues with the ABS warning lights (speedo) plus slopping shifts and throttle response. The tune guy tells me i'll see a bumpy of 20 to 30 HP and more torque, something a few of the guys that have posted on this thread have argued.
I'll have 500 miles on my new gears by the end of today and an appointment tomorrow for the gear oil change. Yesterday was the first day for me to drive it on the highway and I can already feel a huge difference.
