Programming a used Transmission Module
Hello all. I've searched DN and found one similar thread but thought it best to ask the group. I have been asked to program a used transmission module on a 2011 Chev Cruze. Vin above. Is this even possible or are they a one time vin write? Is there any preliminary numbers I might need from the original transmission? Any other insight is very much appreciated.
All Global A architecture vehicles are one time use - NO used modules!!! See GM bulletin PIP4670H
2011 Cruze is listed as a Global car. If the TCM on the old trans is good you can swap them. Then it should run. Problem: see a lot of bad TCMs. So you can use a used trans with a new TCM, but of course the end price will go up! What a dilemma!
Pretty straight forward. If it needs an update it will rewrite the vin. No problems. If it doesn't need an update you will have vin mismatch codes. Which can be fixed with io terminal. Otherwise it's new only. BTW most cruzes need an update in my experience
Everyone is right, I would give it a try updating it. the module are very problematic a new might the best, but its a old car. it won't hurt any to try.
I am going to be the contrarian here. My shop owner also owns a buy here pay here lot. I have purchased 3 cruzes at auction with bad transmissions. The first one with a knot in my stomach, concerning this very issue. I have had the guys at the shop swap out every trans with an LKQ trans. Very cheap used part. Every one of them has worked without problems going on a spread of 2 years. VIN…
I know GM says global A cars computers are 1 time use only but have done it several times and never have had a problem doing it. Will probably have to reprogram it though.
Yep - works fine. I've done quite a few in the last 4 or 5 years.
You can do it just have to get IO terminal it can rewrite that type of module
