How to flash TCM on new GM transmission

[@cutlasssupreme508]

My cutlass 350 rocket doesn't need a computer to shift.. It Just does

[@ttony6538]

Cool story bro

[@J2A61]

It also doesn’t make 400rwhp. It also can’t run on e85. It also can’t be boosted with out 1000’s of dollars It also will leak. It also come with a 50lbs starter It also can’t shift 6-10 times maintaining a great power cover while getting good mpg…. The old stuff is old for a reason my friend. Slap a 5.3 in that cutlass and you’ll never look back… I was once just like you. Even at this very moment my auto 6 speed is giving me the blues. But when I break it out again 💨

New, lightweight, hi-tech designs getting great gas mileage and horsepower: $50k and up. Being able to diag and fix it cheaply at home without a computer and never needing to interact with GM or their network: Priceless

I bought a new 6L80 from GM that I'm installing behind and LS3 which is going into a 1950 Chevy. How do I get the TCM programmed when I don't have a VIN?

[@DionisisTsiapalis]

Hello friend! From your experience do you think I can replace a 6T40 Gen1 from my Opel Astra J with a new one transmission 6T40 Gen2 and programming the new TCM(clear TCM) for my car without any problems at the synchronization with the ECU of my car? Thanks! (The same car with the same engine code after 2012 equipped with a Gen2 6T40)

so you showed us nothing, other than it has to be flashed, you did not show how to flash it.

Do I need to flash tcm if I took my old transmission out and replaced with a used transmission that worked in another car?

[@denisgonzalezblandon1538]

Yes

[@juanescobar1221]

Will it work good if I swap an used transmission and a Tcm from the same car into my car

Dear Sirs: I need advice. I had my 2014 Nissan Versa (53k miles) go in to the dealers to replace a broken CVT cooler line and to get a CVT flush and fill. It was a leaky MESS and was fortunate to get to the dealer in time. They did try to clean up the engine area as best as they could. No new leaks, CVT works well, but afterwards noticed a burned smell. Went back to the dealer for a scheduled oil change, and to check the CVT, and everything looked fine. They said it was residual CVT fluid and will eventually burn off. How long can this take? Can a car detailing help?

You know this is a video about GM trans right??

This is a long shot hoping someone will chime in with some advice. I just had my transmission rebuild on a 2015 gmc Sierra 5.3. - I feel like the mechanic has done something incorrect. he has had it for a month now. has retired it to me a few times and the truck is not shifting correct. once up to full operating temp it will slip badly going into 2nd. Instead of shifting it will go into neutral and the revs will go up fast until I let off the gas , then it will usually clunk into gear , it goes through all the other gears fairly normally. he is claiming that the truck has to go thru a "learn cycle" than can take multiple days of driving it with these symptoms. sometimes it will just stick in second until oi come to a complete stop then it will go back to normal for a little while. it is also leaking a considerable amount of fluid, took it back twice for just the fluid leak and he keeps saying its fixed but then I take it home and its leaking. he said "sometimes it will leak a little at first"....none of this seems correct. the truck only has 80,000 miles on it and I do not think it even needed a transmission , the whining noise it was making that brought me in the begin with has not been resolved with the rebuild. this shop is where my warranty required me to take it and has very good reviews so I felt like it was a reputable shop. Is it true that a 2015 gmc transmission requires a re-learn period like this and do these sound like normal symptoms of that? I paid a lot of money for this truck and feel like this guy may have destroyed it. the amount of time it is taking is also excessive seeming to me.there is no check engine light coming on so he says it is normal process.

[@erasedfromgenepool.4845]

He's full of shit .they don't leak a little. That's a bullshit line he's feeding you... Call a dealership and don't pay the Scumbag who told you that. Its a new transmission it should work like the car is brand new . idk what he did but he screed something up and not telling you!

[@peanutbutterisfu]

The transmissions in ur truck have adaptive shifting so they need to learn your driving habits basically so it will shift like crap for a bit. Also these transmissions even when there is nothing wrong with them shift like crap. I own a auto repair shop and there is a Chevy dealership next to me and I know a lot of the guys there and they get these shifting complaints all the time specially after they do a rebuild and people get pissed off when they tell them it’s normal or the transmission needs to learn. Also some times updated parts are installed to avoid problems which can cause transmissions to shift differently and that’s just how it is. I had a customer keep calling me and yelling at me about his transmission I told him he has to drive it to relearn and he came in yelling at me and threatening me. Then a week later he comes in to say he was sorry he called the dealer and they told him that he did need to drive it and by the next week it was fine.

[@scottrowley9793]

Losing fluid is never normal ( and don't give a ____ who'd say otherwise) but it does need to learn your driving habits

[@garnethartwell5411]

There is a censer in the transmission that consists of a nickel sized piece of plastic that controls the fluid going into the transmission if that piece plastic is damaged in any way at all it will not control the fluid as intended and it will cause this shipping and periods of hard shifting. It’s mainly the 6 speed giving trouble is my understanding and I am on my 3rd transmission however it can be an easy. The biggest issue is reflashing as you see in this video. Plus yes it does require a relearn period and I was recommended to try to drive it around at a continuous speed if possible and not high speed for the first 30 to 50 miles

[@Joeybearhvac]

Good stuff, I have the same problem I need to flash my transmission how it cost to do that?

[@78heloman]

Why couldn’t you just swap the old tcm into the new transmission?

[@dixbuiltit1293]

could have been damaged

[@kotasanti1985]

@@dixbuiltit1293 can’t you just clean the solenoids on the TCHM instead of buying a new one and paying to have it towed AND programmed ?

[@dixbuiltit1293]

It’s possible , but would you risk it? Too much of a pain to remove it

[@donaldcofield3306]

How much do it cost to flash the time

[@eddiesheeran5791]

I'm an engineer and I absolutely HATE what the automotive industry is doing. Computer INSIDE the sealed transmission body? Awesome, you're all fired for being stupid on purpose.

[@aaronhuff4484]

If an exact reman trans is put in and it's exactly what came out a re flash is totally unnecessary just disconnect the battery clear the computers capacitors and hook it back up. This re flash bullshit is just a money thing.

[@vhp454]

Wow, you must be an idiot. A reman transmission comes with a new TCM, there is no data on it. I just did a 2011 Chevy HD 3500 with a 6L90 transmission, I have the software for GM, I enter the trucks vin, I then program the TCM. The so called box that this video shows is from snap on tools, you have to use the box if you are using the modis or better scanner. So you may get the exact transmission, but not a loaded TCM.

[@zero00044]

Not much of a "how to video" lol

[@codydasher4916]

What if it's a six-speed but the techum is not inside the transmission do you still have to reflash or can you just reset it

[@gavenmax378]

Yes
