Before we could begin testing, there were still a few final details to be worked out. For our testing, we used the water jet cutter to slice out a few pieces of steel that mimics the thermostat in the open non-bypass position and Mike welded them together. You either buy a new cooler or find a way to make the failed thermostat work. Half of our audience wanted a thermostat, the other half did not. I recently purchased a transmission oil cooler for my dodge ram from Parts geek, the transaction was simple and secure, I received the part within a few days and not only did the part fit exactly like the original but parts geeks prices were far lower than anyone else I could find. Dan designed a housing that could incorporate our thermostat and devised a block-off that can replace the thermostat and keep the system in non-bypass mode.
If you ever want to go back to stock, the factory cooler will mate up to the cut lines with hose clamps without a problem. After all the design time, welding, prototyping, and fitting, we were more than anxious to test the cooler and see if all our work would pay off. Removing the intercooler was second nature to him and before long, the stock transmission cooler was sitting next to its former home. Because of that all-to-common failure many owners opted to install coolers without any thermostat. This positioning will allow you to swap the thermostat out without removing or draining cooler.
So, to satisfy both, we needed to find a way to allow the cooler to work with or without a thermostat. Many customers either cut their stock lines behind the fittings, adding straight transmission cooler hose to connect to the cooler, or replaced the entire line with standard hose and clamps. However, Rams in colder climates might need the thermostat to help the transmission warm up to operating temperature. After months of work, the test fit was complete. When that happens, the transmission fluid travels in a loop around the cooler, bypassing the cooling fins and overheating the transmission.
Thanks for reading, -Steve Hey Steve, Not to be a pest but I am delaying my my Firepunk transmission build until I can get your transmission cooler. Any updates, pricing, and ordering information??. The access port for the thermostat is also on top of the transmission cooler. Instead of utilizing the factory style quick-disconnect fittings, our cooler features hose barbs designed to securely hold standard transmission cooler line with hose clamps. The stock thermostat tends to fail with age. Our much larger, much better-looking replacement took up residence in the truck with only two bolts. That left us somewhere in the middle.
From the sounds of things from your reply a couple weeks ago, presale should be starting this week!! As our volunteer truck rolled into the shop, Dan began gathering his tools for a short, and ultimately rewarding, install. After 14 years of water, dirt and road salt, those quick-disconnect fittings were more like slow, painful, frustrating-disconnect fittings. Unfortunately, the stock thermostat itself is not available to buy on its own. Keep an eye out for the next post and, as always, let us know what you think. The stock lines for the 2003-09 Ram utilize a quick-disconnect style fitting at the cooler. I will definitely purchase any future parts from them.
