The LT1 That Could

you just have to buy the entire gauge cluster.....around $400 or so

or you may be able to retune the PCM, not totally sure.

here is a link to some pics there are a couple of the cluster. I purchase mine on ebay. Some of the sellers will program your mileage into the new cluster for an additional fee.

What about just the overlay, I think that's what 02blue stepside has

Yep, that's correct. If you do the cluster swap, the trans temp gauge will work fine.

The speedo is what stopped me from buy one. IMHO, it ugly. I got the 06 Silvy SS guages.

I have the full cluster, not just an overlay. The 120mph speedo and the tranny gauge will work when plugged up, no mods needed. My cluster came with a sticker to put on the door jamb stating the mileage the cluster was changed at, but I wanted the correct mileage on the cluster so I had it programmed. Like said above, some places you buy them from will program them, other wise you will have to find someone to program them.

Install is easy. Remove the bezel around gauges, radio, etc. Take 4 screws out that hold the cluster in, and unplug the cluster. Install is the opposite of removal.
