    I am wanting to put a trans temp gauge in my 1500 silverado and was wondering the best way to do it. My uncle's 2500 has a trans temp gauge in the gauge cluster in the dash. Would it be possible to find a used gauge cluster from a HD 2500 or 3500 and replace mine with it and somehow hook the trans temp to a sensor? Has anybody tried this or know some one who has tried it? I have looked all over and can't find anything.

    This is the best way to add a trans temp gauge IMHO.

    You already have an engine oil temp gauge in your dash. Find the engine oil temp sender and buy another one just like it. It is threaded with pipe threads not machine threads. Take your new duplicate engine oil sender to Home Depot and buy the female fitting that fits it perfectly. Now take the trans pan and the sender to a welder and have him weld it in so that it serves as a drain plug as well as a temp sender. Wire both temp senders to a switch in the console or some place easy to wire and easy to reach while driving. When you're towing and want to check in on the trans you flip a switch and now you're looking at the temp of the trans flip it back and you're back to oil temp.

    What most guys are doing is putting in a Escalade Dash Cluster........Also the 99' up NBS 1/2 Ton Silverado's/Sierra's are pre-wired from the Factory for the Trans Temp Gauge, and last if you do pick one up, you will need to have it reprogrammed for the Current Mileage on your Truck......E-Bay has the Best pricing on the Escalade/Denali Dash Cluster's

    Also remember you need to get a Cluster that is within the same Model Year as your's.....meaning a Cluster from a 99' to 02' Model, will not work for the 03' to 06'

    I put one in my 2002 Z71 ECSB from a 2001 1500HD and the guage worked immediately,I had the correct mileage programmed in the odometer by Charlie at Florida Speedometer(954-818-8188) and had him resolder the board while he had it so I wouldn't get the blank odometer/gear selector problem that is common. Personally I think the best looking one is from the Yukon Denali ,NOT the Escalade(hate it,looks like a antique radio In Grandmas attic). Be careful, the 1999-2002 look the same,BUT 1999 is unique in the circuit for the air bag,it won't work right in any other year and vice versa.
