Transmission fluid temperature is the single biggest contributing factor to the lifespan of your automatic transmission. Having an accurate, realtime measurement allows you to know when to downshift or when to take your foot out of it. Whether you’re towing or simply trying to harness the power of a built or boosted motor, AutoMeter’s Trans Temp Gauge will give you the most accurate possible measurement for the exact temp of your trans fluid. A single wire 1/8” NPT temperature sender included to be installed in your transmission, transmission pan or with an optional transmission cooler line manifold is available for easy installation into a transmission cooler hard line.

I was given this 4357 gauge but missing the temp sensor. What is the part number for the temp sensor I need for this 4357 gauge?

Asked by: Fievel22
Thank you for your question. The 4357 uses sensor #2258.

I have a trans temp gauge # 4357. The sending wire for the sensor on my oil pan has been cut a couple of times. Is the gauge still going to read accurate temps or was the wire critical length and type specific?

Asked by: Pandora
Thank you for your question. The wire length is not critical to the readings on this gauge. As long as the wiring has been soldered and the connections are secure, the gauge will still function just fine.

Does this gauge use volts to ground to determine temperature? What is the volt range? How many volts pass through the gauge when cold (100 Degrees)? How many volts pass through the gauge when hot (250 degrees)? 

Asked by: ScottL
Thank you for your question. This gauge reads temperature via resistance from a sending unit. Voltage along the signal wire is not relevant to the temperature reading.

Asked by: davedieselguy
Hi Dave, thank you for the question. There is usually not a specific port on the transmission for temperature. Some later models may feature a pressure port that may accept our electric sender, otherwise we offer a transmission temp manifold that allows you to "T" into your tubing that is running to the cooler. Those models are available in 2 tubing size options under 2286 and 2287.

I have this guage, any idea why it reads 150 when cold, and is maxed out after afew mins of driving. Checked actual temps and the guage is 150 off

Asked by: Nathan,
Hi Nathan, thank you so much for contacting us. By far the most common reason you'll see this is inadequate gauge grounding. I would recommend making sure the gauge's ground wire is connected to either the engine block or a chassis rail. I would also not recommend tying the gauge ground in with the gauge light ground (we separate out those intentionally). This fixes it 99% of the time. For a much more detailed rundown on a short sweep gauge reading high, check out this article we wrtoe: https://www.autometer.com/resources/index/faq_view/id/11 Hope this helps!
