What's poppin! We don't know what to do to liven up the website!

The majority of people on fb are annoying.

@  ejguillot : (21 September 2018 - 03:03 PM)

Agreed. I'd rather pay money to keep this site going than be on Facebook and having everything on there be used to make a buck for Zuck and company.

@  Vicious6 : (20 September 2018 - 01:48 PM)

We need to get this place moving again! Post link to this site on every social media site you know! Been around too long and we can't let it go down..........

@  Vicious6 : (20 September 2018 - 01:08 PM)

Seems everyone is too stressed to be online and worried about where their next meal is coming from! Rough times right now!

2004 Transmission in to my 2003 GS?

Ok, so the interchange manual says that the 2004 trans is a one year only part.

But, from what I have been reading, the 2003 and 2004 trans is the same (meaning same wiring harness and plug as well as the solenoids, etc) except for the converter that was shipped with the unit from GM. They have a different K-factor (stall speed).

 

Can anyone confirm or deny if this trans will work in my '03 GS?

 

Thanks in advance.

I believe rhe wire harness changed so the pinout will be different. Not 100% sure but when I was looking to do something similar that’s what I remember

OK, I'll check into that as well.

Do you know of any online sources for the wiring diagrams for those two model years?

So, I wound up doing a lot of research on the two model years. Here is what I came up with - The part numbers for all of the electronics are the same. The plug for the electronics is the same, the PRND lever was the same.The torque converter shipped with the new 04 trans was the same K-factor as was required for my 03 Regal. Transmission lines (which are supposed to be different) were the same.

 

The interchange manuals say that this trans will not work in my 03 Regal - BULL!

 

I put the 2004 trans in my 2003 Regal and have been driving it without any issues for about a month now.

Thanks! I almost forgot to come back and follow up on the thread.

I don't know how many times I've run across threads on forums that are 100% related to information I am looking for, only to find that the thread just dies off because somene stopped updating it with good info....lol

Having an 03 for so long I’ve pretty much have everything down expect the transmissions interchange. I know the oem 03/04 has minor upgrades to parts that fail in the earlier years but other then that, I’ve never tried to swap a different year into it.

Glad it worked out for you.  I have a rebuilt transmission that I pulled from my 99 GS.  Looking at an 03 GS for my wife that has a bad trans.  Any idea if the 99 trans will work in an 03 GS?

I would bet the electronics are different but you never know the 04 worked in the 03.  Would be interested to know though.

I know that the PCM and the wiring and plug are different.

That's too bad.  Which years are supposed to be compatible?  I know the 97.5 is different altogether, but what about 98-04?
