05-06 pcm in a 04 RL?

dL_RL · 02-27-2006, 01:19 AM

Will a 05-06 PCM fit into a 2004 RL?

If I picked up a used 05 pcm will it work in a 2004 RL?

I know physically it will fit, but will it trip out?

There is absolutly no reason it wouldn't

So would it be possible to program an 04 PCM with an 05 or 06 PCM program? When I get to work today I am going to ask one of the techs and see what they have to say.

i would suggest not getting a used one... you have to re-program the PCM when you replace them.. to give them the right vin and cars info.. getting a used one might screw you over during an inspection

I reprogramed my 04 redline a couple of months ago and checked the program calibration ID# between an 04 and an 05. They were the same ID#. So anytime GM has a updated program they put them in all year redlines. All you have to do is get a dealer to reflash your PCM, since they have the stuff to do it.

No they wouldn't. I asked them them to upgrade mine to 05 programming and they looked at me like I was crazy.

Well they probably did look at you crazy. Most service writers and techs don't really pay much attention to program id#, so what your were asking seemed off the wall to them. All you need to due is get most updated programming for a 04. Programs are updated all the time for various reasons and put into older model years since they may see the same problem. All I know is what I've seen.

Dude, that is one of the funniest things I've ever heard on this forum. I almost pissed my pants. But I wasnt thinking about his avatar. I imagined a RL (the car) going to a service writer and saying "upgrade my ECU". Was laughing my balls off
