GM TCM Programming with New Techline Connect SPS2 and J2534

GM recently have replaced the SPS for the SPS2. The website is the same. You just have to buy your subscriptions basically on if you have the subscription already.

Today we have a 2012 Chevy Silverado with a 5.3 engine. We’re going to do a transmission control module programming with the new gm system- SP2.

Let’s get started.

Go to ACDelco.com

once you put your subscription you go to review- Admin

the system is a little bit slower than the other one

so if you have not downloaded the Techline Connect yet

you will have to download it from here

Now the gm changes system basically they came out with the software called Techline Connect

It has the gm software gds2 and it has a sps programming in it together so basically if you paid a subscription off about $3900 and change almost $3900 or almost $4000 you can have the whole year of gds (global diagnostic system) and also the sps system

but sp system you still have to pay 40 dollars for each vehicle that you’re trying to program.

but it’s all in one system now and you will see it so mine is already downloaded it’s not a hard situation i mean it’s not a hard case if you guys know how to download programs

that’s very simple you just have to make sure your firewall and windows diff windows defender and any type of antivirus is all deactivated.

i’m just going to go Launch Techline Connect

By the way this car they changed the transmission they put a rebuild transmission in it

but the computer inside the transmission control module is brand new from the dealer

first i just hit SPS2 and then press Connect Vehicle

and then from here we’re going to select for passthru device

Here we select (Autel IM608) MaxiFlash JVCI j2534 (you can use other J2534 adapters, Maxiflash VCI, VCMII, MDI, MDI2, VXDIAG VCX NANO for GM, VCM3 etc)

Press continue

all right so it’s gonna try to communicate with the vehicle

so we’re gonna do “Replace and reprogram”

that’s what the new interface looks like. this actually looks pretty decent

when you go to dashboard you can switch over to the gds

but we’re just going to be using sps2

right now so i’m going to hit the Replace and reprogram

i’m going to hit next

the prompts are the same it just a little bit look a little bit different looks a lot more modernized like the old one

we’re gonna find the transition control module right here

press next

is checking how many vin slots i have in the acdelco tds.com

this is my last one so

yes it will take one of my slots right now

it’s basically locking my subscription to this vin number at the moment

just reading the information went up

the cluster started making some noises, some beeps warnings chimes

okay here we go

as you see current calibration unrecognized calibration because this module is empty right now

we’re gonna go ahead and hit next

before we should put our own battery maintainer to the vehicle

Press next

address counter among addresses the customers complained of two to three

called upshift players i guess is the new software there was a software update

on this thing from the original software itself transmission diagnostic and system

so go ahead next

you can read pre-programming guide carefully

it’s saying basically something doesn’t work after the after the programming just don’t replace it just

you can just cycle the battery you turn off and then on but you should be back to normal again

look next

confirm ECU is replaced


it’s going to download the software

the calibration file has been already downloaded and right now it’s going to start writing the

new calibration file into the transmission control module

started programming the transition control module until completed.

i just see the traction light just went out

the transmission being programmed successfully there’s no problem with it

Press later it’ basically telling me that my vin slots have been changed because i had only one left

before now i have zero i have to buy more

turn off the ignition for 30 seconds

Hit clear DTC’s

clear all DTCs

and then after 30 seconds we can react to vehicles start the vehicle see if actually the transmission is shifting and then go for a test drive

let’s see if the lights are on

so it looks like it did the job correctly

there’s no issues

Hope this will help somebody out.
