• WhichTransmission Cooler Fittings for a 2007 GMC Truck
  I spoke with my contact at the manufacturer and he said that there are 3 main types of fittings that GM used during that year and that it was more or less random for the GM trucks so you may need any one of the three types. The three types are the fittings that were used are the fitting supplied with the cooler, a snap in style fitting, item # D13035, and the Derale Radiator Adapter Fittings for GM, item # D13018. I believe the last style of fitting is the fitting your truck will need....

• Transmission Cooler for a GM K3500 Pickup Truck with a 6.5 Liter Diesel
  We generally recommend going with the largest cooler that will fit in the space available in the engine compartment. The Most popular cooler for the K series with the 6.5 liter is # D13503 that you have referenced. It measures 11 inches wide, 8-3/4 inches tall, and 7/8 inches deep. You can get more cooling efficiency using a stacked plate cooler. I would go with # D13403. Even though it is smaller the stacked plate design is more efficient so it is rated higher than the plate fin coolers. You...

• Recommendation for Cooling the Coolant and Transmission Fluid Temperature on a 2008 Chevy Avalanche
  For the radiator coolant temperature, I recommend adding a supplemental fan or fans depending on how much space you have under the hood. There is no limit to the amount of fans you can have. A pusher fan, mounted in front of the radiator pushing air through it, would be the most efficient (provided that the factory fan is mounted on the same side and pushes air through in the same direction). A puller fan would be used on the other side of the radiator to pull air through. The largest electric...

• Recommended Weight Distribution System For 1997 Chevrolet Suburban 2500 w/ 10,000 lb Towing Capacity
  Your 1997 Suburban K2500 4x4 has a 10000 lbs max trailer weight according to your owner's manual, so you cannot pull a 12,000 lb fully loaded trailer. You can pull the 12,000 lb capacity trailer at a maximum load of 10,000 lbs. There are hitches that are available as you stated that rated higher than your vehicle capacity. Unfortunately that only means that the trailer hitch receiver can handle that weight, not that your vehicle's transmission, engine, and suspension can handle that weight....

• Transmission Cooler Recommendation for a 2003 GMC Yukon XL 2500 6.0 Liter
  Adding a supplemental cooler is a good idea, but you do not have to replace the factory one unless there is something wrong with it.

When looking at transmission coolers I recommend going with the largest one that will fit in the available space in the engine compartment. There are 3 main locations a cooler can go: the most efficient is in front of the air conditioner condenser core/directly...

• Should 2007 GMC Sierra Classic be Put in 4WD When Towing a Heavy Load Long Distance
  I checked out the online version of the owner's manual and it looks like for your 2007 GMC Sierra Classic then you want to use the Tow/Haul mode for heavy towing and/or shift the transmission to 3rd or lower if it is shifting too often. Aside from that though it doesn't state anything about 4WD so I wouldn't worry about it. You may consider adding a transmission cooler like the Derale # D13502 to help keep your transmission from overheating and making your engine work harder. If you have...

• Where is the Transmission Return Line on a GMC Sonoma
  I really wish I knew exactly which transmission line on your GMC Sonoma was the return line but unfortunately, I do not have this information. However, if you drive the vehicle around the block and then grab each of the two transmission lines that lead in and out of the radiator that should give you a very good idea of which is which. The return line should be considerably cooler. Please note that in order to install a transmission cooler on a GMC Sonoma you may also need to use the Derale...

• Transmission Cooler Recommendation for a 1998 Chevy K1500 Series Truck
  Factory transmission coolers are adequate at best at keeping the transmission fluid within the optimum 160 to 200 degrees F range. Adding a supplemental cooler is a good idea, especially since transmission fluid cannot be over cooled. If you do towing, hauling, or are otherwise looking to get the most life out of your transmission then adding a supplemental cooler would be a great idea. Cooler # D13504 is a good choice. To avoid having to cut and flare lines I recommend adding hose fitting...

• Transmission Cooler Recommendation for a 2012 Chevy Silverado 2500 HD
  Transmission coolers are not vehicle specific so you can install any one that will fit including # D13504. For the 6.0 liter engine you may need fitting # D13035. If you have a hard metal line and do not want to use the fitting, you could cut the metal line, flare it, and use hose clamps. The transmission cooler comes with hose, clamps, and mounting hardware. It also includes an Insta-dapt radiator adapter. This adapter is if you have a rubber line, not a metal line, so you can use the...

• 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...

For this installation you will also want the Derale Snap-In Radiator Adapter Fitting for GM # D13035 if you have the snap in transmission line or the Derale Radiator Adapter Fittings for GM # D13018 if you have the threaded fittings on your Escalade....

• Transmission Cooler Recommendation for a 2012 Chevy Traverse
  First, you do not necessarily have to remove the front clip on your 2012 Chevy Traverse to install a supplemental transmission cooler. It just makes installation a lot easier if there is nothing in the way. We have not yet installed a transmission cooler on a Traverse so I do not have a video or specific instructions on removing the front clip. When our installers perform an installation they have to determine where the fasteners are that hold on the front clip (if it is a vehicle they...

• Recommended Transmission Cooler for 2001 Chevy Silverado 2500 With 6.0L V8
  I took a look at the owner's manual for your 2001 Chevy Silverado 2500 and was unable to find any information concerning specific grades of hills and there isn't any type of specific formula that is used which has this information. The only thing mentioned in your owner's manual was that going up steep grades would cause overheating so I strongly recommend using an accessory transmission cooler. The best option is the Derale Series 8000 # D13504 because it is a plate-fin cooler that is...

• Transmission Cooler for Towing 5300 lb Trailer in the Mountains for 2007 Chevy Silverado 5.3L
  Since you will be towing in the mountains, which is hard on a transmission, I would recommend getting the largest, highest rated transmission cooler that will fit your vehicle. You cannot over cool a transmission. The ideal install location would be in front of the radiator and A/C condenser, right behind the grille. The # D13102 you mentioned will provide some cooling, but due to the fact that you will be towing up and down mountains, it would be too small for your needs. The largest...

• Transmission Cooler Installation Location on a 2012 Chevy Silverado 1500
  Your 2012 Chevy Silverado 1500 most likely has the GM 6L80 transmission. On this transmission, the bottom line on the transmission should be the return line (based on some research I did online for this transmission). You should be able to install the transmission cooler like you have described provided you have enough hose to reach. If you install it at the steel lines then you can use a hose fitting, # D13018 for the 4.3 liter or # D13035 for any of the larger motors, so you will not...

• Transmission Cooler Recommendation for a 2003 Cadillac CTS
  When it comes to picking out a transmission cooler for a vehicle there is not a list of confirmed coolers that will fit different vehicles. The best way to pick one out is to measure the area in front of your radiator and pick a cooler that will fit in that area. If you have the room I think a Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13502 should work well to cool the transmission fluid of your 2003 Cadillac CTS. The measurements of this cooler are 11 inches wide, 7-1/4...
