2006 5.3ltr chevy silverado z71 p0455 andp0449

2wd or 4wd?
learn this first
4l60e is not full spec part number ever, it is ONLY a series class only.
read the ATSG manuals on this box it tells you that in chapter 1.
the list of tranny swaps are endless, (HUGE)
learn that the gear ratio's most be the the same or the TCM will go MAD (chaos)

1. fits bell.mount to engine,
2. same length or 4wd fit up or tail shaft.
3. mounts that same
4. same gear ratios'/
5. same solenoid shift patterns and TCC lockup.
6. and more lots more. really what could be harder to match?????

ask your transmission re-builder this. they have an expensive data base access that answers all this that most never want to disclose. after all why help you buy elsewhere./??? Realty 101

the transmission has sub codes on the side label
THOSE MATTER TOO

Simply disconnect the old one and put in the new battery.This will also clear any codes in your check engine light system.

P0455 Evaporative Emission System Leak Detected (large leak)
The large leak detected could be in a hose or connector leading to the front under the hood evaporative canister.

It is not a loose gas cap, though.

Go to your local autozone where they can hook up their scan tool for no cost to you. Be sure to write down the codes and definitions of the codes and repost if you don't know where to go from there. Also, I don't recommend replacing parts just because the guy at autozone tells you that's what you need (ie, they will tell you to replace oxygen sensors if an o2 sensor code comes up).

It's the transfer case vacuum switch. Easy fix.

try cleaning your idle control valve, make sure you dont have any codes in your computer, if you do address those codesl

A little late but check your gas cap first.
