How to tell what version trans software

Is there a way that I can tell what version software my transmission ecu is running or do I need to take it in to the dealership?

 

No one?

 

Can't tell

 

If it's had an upgrade there should be a sticker on the underside of the hood. If no upgrade has been done I think the dealer would have to check.

 

Try asking a tech to show you?

 

Many performed the update and did not issue a sticker

 

I'll check the hood tomorrow. Would they have done an upgrade before I purchased it? I would guess no, but who knows.

 

I'm curious as well. I haven't experienced any issues so I am wondering if it was done prior to delivery?

 

Shoot you're lucky if they filled the transmission fluid or greased your zerks

 

Does it involve buying an ECU reader to do it? If so, is there somewhere online that shows you how to get the info?

Even then, unless it's something that can be revealed without having to do that I'll probably just take it in and have them flash the ECU, if needed.

 

Ha. Kinda what I thought.

 

Well I purchased mine October 16th and it needed it. Was made September 19th.

 

Got mine first week in November. No idea when it was built.

 

Look at the sticker inside the drivers door sill

 

Download the Toyota owners app. Update your information. Your Tacoma's service history should be on there. My Service history shows my transmission software update. I have no sticker on my hood either.

 

Yes this is what the service writer puts into the system reflecting on your history. Unfortunately there is not really a practical way for the consumer to really know what was performed without witnessing in person what the dealership did.

 

Here is a picture of my Toyota owners app. This shows my service history of my transmission update.

 

My OBDII scanner shows the calibration code. Maybe the ones that auto parts stores let you use would do the same?

Edited to add photos:

 

Looks like it was built 10/16/16 Not sure if the transmission ECU version can be deduced from that, though.

 

What about the 2017 Tacoma Pro? Would they have had the update?
