How does an automatic transmission oil cooler work?
How Does a Transmission Cooler Work? Fluid heated by the transmission, engine, or power steering pump flows to the cooler. Air flowing over the fins of the cooler carries away heat and cools the fluid flowing within the fins. The cooled fluid is routed back through the transmission via the return line.
Do transmission oil coolers work?
As long as it is properly installed, a transmission cooler will not affect a factory transmission. It is a flow-through device and does not affect any internal components of the transmission. A transmission cooler will just help to prolong the life of the transmission by keeping the fluid cooler.
Do all vehicles have transmission coolers?
While all automatic transmission equipped vehicles have a transmission cooler in their radiator, this might sometimes not be enough to properly cool your transmission fluid.
Do you really need a transmission cooler?
Transmission coolers help to protect your transmission when you turn up the heat. For the same reason, the addition of an auxiliary transmission fluid cooler isn’t just necessary for those who tow trailers anymore. …
Can you have too big of a transmission cooler?
Too big could be a concern if mounted in the front of the rad creating a loss of air flow to keep the engine cooled . Years ago , GM released a TSB about overcooling the transmission in cold climates . Transmission fluid would actually turn to somewhat of a gel .
Is it possible to over cool a transmission?
Heat is a huge cause of transmission failures but running too cool is bad also. Just as an engine has to run hot enough the trans has to run hot enough to get rid of any condensation that builds up inside and to keep the viscosity at the correct level for best operation.
What temperature should an automatic transmission run at?
175 to 220 degrees
Does a 4l60e have a temperature sensor?
GlowShift’s Stubby Transmission Temperature Gauge Sensor was created for anyone looking to install a Transmission Temperature Gauge into a car or truck running a GM 4L60-E automatic transmission. This GlowShift Stubby Temperature Sensor was built to work with a specific set of GlowShift Gauges.
What temp should a 4l60e run at?
Open freeway below 80 dregrees it runs around 160. Above 80 and it runs around 180-190 Towing a 6000 lb trailer around it stays around 190-200. On long grades it will climb to 215 or so.
Does the 4l80e have a temperature sensor?
Yes, there is a factory trans temp sensor in the pan, if you have a scanner you can compare it to your gauge. It is wired through the round big gray plug on the drivers side, it is made into the internal trans wiring harness.
What is the operating temperature of a 4l80e transmission?
The GM engineer’s say 200*-210* is normal temp for driving a HD truck with the 4l80e transmissions. Once you get over 240* you start hurting parts inside it. The perfered temp though is 200* at all times but if you pulling heavy loads then the tans will see higher temps.
What is too hot for transmission temp?
The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.
What is the normal transmission temperature on a 2007 Silverado?
between 160 and 200 degrees Fahrenheit
Which line is the return line on a 4l60e transmission?
The 4l60e top port is the return line, the bottom port is the pressure line. The bottom pressure port on the tranny should be hooked to the top port on your radiator. The bottom port on your radiator is the return and should be hooked to the top port on your tranny.
