Expert Answers about Chevrolet Transmission Coolers

• Will Aftermarket Radiator Solve Leaking Transmission Cooler Problems in 2006 Nissan Xterra
• From what I can recall, the problem with the mid 2000's Nissan truck radiators was that the combined transmission cooler/radiator would develop a leak that allowed coolant to mix with the transmission fluid, which damaged the transmission. Installing an 'OEM quality' aftermarket radiator with the integrated transmission cooler is the recommended repair, which will solve the leakage problem. Over the years, we've gotten numerous questions about this from folks who just want to cap off...

• Troubleshooting Transmission Fluid And Engine Coolant Mixing On 2003 Cadillac CTS
• Sorry to hear about the problems with your brother's 2003 Cadillac. The first thing you will want to do is have the transmission taken care of. I am not aware of a separate cooler for the transmission located under the intake manifold. Typically what is used is a line that runs from the transmission to the radiator. The radiator holds engine coolant and the transmission fluid line is run inside the radiator as well. The radiator cools both the engine coolant and the transmission fluid...

• Will Aftermarket Derale Transmission Cooler Bypass OEM Cooler on a 1998 Dodge Dakota
• A supplemental transmission cooler like the Derale # D13614 is designed to work in addition to the OEM cooler on your 1998 Dodge Dakota. So no, it won't be rid of your current transmission cooler. The adapter kit # D13028 is exactly what you need to perform this installation. Just make sure that you have enough room in your engine compartment for this cooler (see attached photo).

• Troubleshooting a Derale Remote Transmission Cooler in a 2004 Dodge 2500/3500 With Exposed Wires
• Derale manufacturers remote transmission coolers that do have two wires, however, the Derale Series 8000 Transmission Cooler # D13504 that you reference does not have any wires. If you do have an aftermarket remote transmission cooler - there are two types of hook-ups: coolers with a thermostat only and those with the option of either a thermostat or manual switch. The hook-up directions are as follows: In the Derale # D15830, the positive wire attaches to a 12 volt source such as a...

• Troubleshooting Radiator Leak in my 2001 Ford Explorer Sport 4.0
• It's tough to pinpoint an exact leak in your radiator, but it could be the fluid return line. If anything, it may be leaking in the radiator. The factory cooler is inside the radiator. Transmission coolers such as # D13503 will not be inside a radiator. They attach in-line with the transmission fluid return line. The usual spot a supplemental transmission cooler is mounted to is in front of the AC condenser or at least in between the air conditioning condenser and the radiator itself....

• Will the Transmission Cooler Snap-In Radiator Adapter Fitting Leak Transmission Fluid
• If the Snap-In fitting, item # D13035, or the OEM transmission line snap fitting is removed from the radiator on your 2006 Chevrolet Silverado, you will leak some transmission fluid that will need to be replaced. You will not leak any anti-freeze because the fluids are not mixed. The anti-freeze coolant is circulated around the outside of a small transmission cooler that is installed in the radiator tank. If your snap fitting is leaking before the installation of the transmission cooler,...

• Engine Runs Hot After Derale D13504 Transmission Cooler Installed
• What is currently running hot? Your transmission or the engine coolant temperature? The # D13504 is designed to cool the transmission, and wouldn't have anything to do with the vehicle's engine running hot, only the transmission. Changing the thermostat, the water pump and the radiator wouldn't have much effect on the transmission temperature. If it's the transmission running hot, is the factory transmission cooler (or the circuit through the radiator) still connected? Is the Derale cooler...

• Transmission Issues & Cooler Installation in 2009 Nissan Rogue with CVT Transmission
• CVT transmissions can pose a challenge for installation of an aftermarket auxiliary transmission cooler like the Derale # D13503. It can be tough to find the external return line (from the radiator's integrated cooler) which is where a Derale unit will be installed. Some Nissan CVT transmissions are completely sealed, with no way to access the fluid at all. The other issue is that some CVT fluid is very costly and in some cases you may need to spend a substantial amount on fluid for the...

• Troubleshooting High Transmission Temperatures after Transmission Cooler Installation
• I would try reversing the direction of the fan on the Derale Transmission Cooler # D15960 that you have installed on your 1994 GMC Truck to see if that will yield you cooler oil temperatures. Generally speaking coolers loose from 25 to 40 percent of their cooling efficiency when the fan pushes air through the cooler as opposed to being pulled through it. Also, depending on the location of the cooler in relation to underside of your vehicle the fan might be fighting the natural airflow...

• Oil Drip from Unidentified Small Cooler Attached to Transmission on a 2006 Chrysler 300
• It sounds like it could be a transmission cooler. What you can do is when the vehicle is cold, start it up and place it in drive for about 10 seconds or so. Then return it to park and turn off the motor. Feel the hoses and if one is noticeably cooler than the other then it is a transmission cooler. Coolers are normally found inside of the radiator. It is possible that someone has installed a supplemental one on the vehicle if there were other owners before you. If it looks like # D13260...

• 1999 Chevy C3500 Transmission Will Not Shift Into Overdrive While Towing
• Overdrive is not usually something that you would need to use when towing. Also if your truck has a tow/haul button that you press when towing then it likely shuts off overdrive. If this is something new the truck started doing then there are some things to look at. The first thing I recommend doing is checking the transmission fluid level for your 1999 Chevy C3500. If the fluid is low then it might not have enough cooling power. If the fluid is full and looks good then the cooler you...

• Would a Transmission Cooler Help a Vehicle that Stops Shifting After It Gets Warmed Up
• Sounds like your transmission is losing line pressure after driving it for a little bit and then stops working. I have had two transmissions do the exact same thing as what you described and the first time it required the transmission to be rebuilt and the second time I had to install a new torque converter. It's not that your vehicle is getting hot that is preventing the transmission from working. The problem is that there is a ton of junk in your fluid that ends up clogging the pickup...

• Special Radiator Fittings to Install a Transmission Cooler on a 2005 Jeep Wrangler 4.0
• If I understand correctly, the line from the transmission to the radiator goes through a cavity in the radiator where there is coolant before the end of the line reaches the actual transmission cooler inside the radiator. Is that correct? Otherwise the coolant and transmission fluid would be mixing together and that would be very bad. It sounds like the steel line needs to stay in the radiator and you would cut the hose and use fittings # D13028 instead of fitting something directly in...

• Transmission Cooler for 2000 Ford F-250 Towing Heavy 5th Wheel Trailer
• Any fluid leaking from a vehicle is a warning. Often this indicates excessive temperatures in your transmission. If your transmission is stressed to the point of leaking fluid this means that somewhere either a seal, hose or other fitting is being pushed past its limit. My first suggestion is that you try to find that leakage point so you can check whether you have a bad seal or fitting that can be replaced. Driving your truck, let alone towing a trailer with it, with an inadequate trans...

• Troubleshooting Ford F350 with a Hot Transmission
• With two transmission coolers as well as an Edge programmer your transmission should definitely not be running hot, unless your trailer is grossly overloaded or you programmed the shift points inaccurately on your programmer. The first thing I would do is make sure you are staying within the weight limit of your truck. Then I would reset the shift points on the Edge Programmer. If that fails you might have your transmission checked out by a professional mechanic.

• What Makes Coolant Mix with Transmission Fluid in a Factory Transmission Cooler
• The chambers inside the radiator can end up leaking which is a problem for many Nissan owners for certain models and year ranges. It could be from metal fatigue, corrosion, or outside damage sustained in a front end impact. You should know that this occurrence is rare and the vast majority of factory coolers that are inside of the radiator never have problems.

• Troubleshooting Overheating While Towing Boat with 2015 Grand Cherokee V6
• Your 2015 Jeep Grand Cherokee V6, the towing capacity is greater than that, however you still need to use caution. Your owners manual suggests not using ACC at all during towing. It also states that you should follow the gauges which may be more sensitive to heat when towing to remain safe. It could be that your thermostat is misreading, but it is very likely you need to add a cooling system which is normally included with a towing package. Adding coolers will only help your vehicle...

• What Is The Purpose Of Thermostat In Aftermarket Cooler
• The automatic transmission thermostat fits into the bottom of the coolant expansion tank and controls the temperature of your automatic transmission fluid, ensuring that it is always running at its optimum temperature. The check valve function is very simple they direct flow into or prevent flow from entering specific circuits. I would not remove them. The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets # D13503 will fit most vehicles with 5/16 inch transmission lines,...
