I would like to install oil and trans temp gauges in my '02 truck. I found where the oil sender goes; but what about the trans sender??? Someone on the truck forum said something about a plug in the 4L60e and that's where you would put the sender--Is that correct? I would also like to install an aftermarket speedo in the a-pillar. How do I tap in to the factory speedometer wire? Basically so that once my truck speedo hits 100mph the aftermarket digital speedo will keep going--is this possible? I found some gauges in jegs that I would like to use but I don't think autometer makes a 2 1/16" speedo. So, I was thinking I would install the digital trans temp, oil temp and speedo gauges made by Cyberdyne. I would appreciate any help or input on these gauges and how they need to be installed (i.e. senders, adapter fittings, electronic calibrations, etc.). Thanks!!!

 

The lazy man's way to a tranny temp guage and 120mph speedo is to swap out the cluster with an Escalade cluster. I don't believe you can tap into the speedo as it "communicates" with the computer to determine speed. There is a port on my 4l60e if you wanted to add an external trans temp guage.

 

on the drivers side of the tranny near the front there is a plug. remove the plug and install the sender.

 

Cool! Ya thats pretty lazy!!LOL!! How much does a cluster cost? Auto Meter pm'd me and said that I would have to drill and tap into the pan on both. I'm not going to do that! Anyway thanks 4 the info!

 

Were can I get a sender?? The dealership?? Or Autometer??
Thanks 4 the info guys!!

 

The gauges should come with senders.

 

yes, the senders do come with the gauge. i installed my trans temp gauge yesterday.

 

If I recall, I paid around $270 for the cluster from GMPartsdirect.com

 

Where did you install your oil temp sender? I just got the same 2 gauges and installed my trans temp sender in the plug that they mentioned above and it is working great so far, I just need to install the oil temp now.

 

I couldn't find a better way to explain it, so look at this picture: (you could use this for temp or pressure)
