TCM, PCM programming

[Stephen Yale]

Took my 2019 RAM 1500 Rebel in for oil change and state inspection. Service guy informed me there are multiple updates available for my TCM and PCM. They want $399 to do the updates.

Q1, is this cheaper to get done at the dealership?

Q2, Can I do it myself ( I am a technical person)

Updates are USUALLY to you benefit. But four hundred to do them???? Hope he defined what "multiple" means. I see TCM + PCM = 2 total.

I always thought they did them for zip, if vehicle was in for service already.

The dealership quotes $210 per update and only do recalls for free. Is there a a way via obd2 I can see what versions i have and see what is available to see if it is to my benefit e.g. fuel saving etc.

I highly doubt any of the updates are for fuel economy .If the truck runs good and the radio works good and it passes emissions i'd leave it alone and wouldn't worry about the updates,especially if you have to pay for them
