Cluster Compatability

[Jspafford]

Hello All,

I am thinking about adding a transmission temp gauge to my 2004 Tahoe. I know, join the club. Two reasons, one I just has it apart to replace the speedo stepper motor and saw how friggin it easy was to do. Second, both my Duramaxes had one and they may be inaccurate but they seem useful to some extent.

My problem is I cannot find anyone to sell me an overlay with the tranny temp "reading" on it. I find them online for $80, where as the non tranny gauge they only want $20 for.

So, I've been on ebay and found a cluster out of a 2006. I don't know what it's out of, but it has white needles and the trans temp guage installed. Looks like the housing is silverish and not black like mine. I want it, but the only difference I can see is the PRND321. Mine is in a window, and this one is printed on the overlay and a light lights up under whatever gear it's in.

Will these interchange??

I would say your going to be fine with that difference. Same thing is happening with the 03-06 escalades and if yours is a 04 and it comes out of a 06 and has the letters printed instead of digital letters you'll be fine.

If the overlay were different as yours says PRND321 versus PRNDM or PRNDM1. Id be worried if I was you.

I ordered it. If it does not work I am sure I can resell it.

Here is a pic. I was told it was new with 0 miles on it.

Hope it works!

Will let you know.

You are going to get your current mileage set on it right?

Is that necessary on our rides? When I swapped a Sunfire cluster into my Cavalier it registered the same mileage it had before the swap.

Yes Sir, as soon as I make sure it works with my truck.

Wouldn't it be nice to have a 2004 tahoe with 0 miles on it again. But I think the carfax would give it away.

That cluster looks just like mine. I drive an 03 Denali but, the only difference I see also is the gear selector is different in mine as well. I would think this came out of an 06 Denali. They are all interchangeable from 03-06

Got it today and installed it. It looks as if everything works. Mainly the PRND321 work fine even though it is the newer style.

Only thing I noticed is some of the functions are gone. My old one had "personal", "business" miles and seems like some other things this one is missing. I have 'trip a" and "trip b" which is the same thing, but there are definatly some functions not there anymore.

When I have it programmed, will these come back?

Not sure the transmission temp guage is working. I drove about 15 miles at 65mph and it never moved off 100. It is 32 degrees out. Anyone with a tranny guage. Do they move when it's cold out? How can I test it?

Do you have the sensor? I would imagine no gauge no sensor?

I drive an 03 denali as well and I have a sticky speedo. Can I get one from ebay and be good to go or do I need to go to the dealer to get it programmed? Of course the dealer is going to want me to do that but I dont want to spend the extra dough.

Also, can I drive without a cluster if I send mine out to get rebuilt?
