Hello Guys,

New to the tuning of automatic TCM, I have been looking at the GPEC 2A tuning and engine side, but recently wanted to dig into the TCM, I noticed that for the cars I have purchased 2 credits (Jeep JL Wrangler), I dont see enough information on it. (refer to this photo)

While in I should see TCM set points and other information as per the below photo.

I usually purchase 2 credits and I am able to see all engine related parts but on TCM never able to see all these details. How can I see this to be able to tune the TCM, can anyone help me here please in case I need to add more credits, which type of credits for my MVI3 device and how to be able to see the TCM data?

Hello,

Per your first picture, Manual Transmission is enabled. Just for "sanity check": Do you have ZF 8 speeds in the vehicle?

Also, which year is your vehicle? In case 2018+, you have to have "Smart access cable": https://www.hptuners.com/product/dod...-access-cable/

In case you have ZF 8 speeds, you dont need credits to read TCM (only to write).

Thanks.

Yes, I read lots of auto cars, only the capture I shared by mistake is coming from my manual Wrangler 2018+. All these cars I am referring to are 2018+. I use a cable for bypassing the security gateway of jeep JL, as mentioned I can see all the car fuctions, engine tune read and write tunes. Do I still need to get the cable you mentioned while I use this one?

Can you guide me a bit with few photos on how to see the transmission part from special functions and how to buy credits if I already see the car engine details? If there is no issue in that
