LUBEGARD Kooler Kleen High Pressure Transmission Cooler Flush (Water Based Formula) works like a fire hose, jettisoning away grease, dirt, sludge, and metal shavings that taints transmissions. And it inhibits their return! It’s all about the high pressure dispensing and proprietary formula that contains no CFC’s or chlorinated solvents. For those who prefer water based cleansers, this is your Trans Flush!
- High pressure water based formula physically removes gunk from transmission cooler lines by flushing out grease, dirt, sludge, and metal shavings
- Prevents costly comebacks by eliminating build-up of new or rebuilt units and inhibits the return of foreign deposits including rust which reduces claims
- Contains no CFC’s or chlorinated solvents and leaves no soapy residue
- OEM and large rebuilder approved; ideal for those that do not have a dedicated flushing machine
- Standard 5/16″ fitting

Works great. Allows for a through transmission flush

I used this to clean out the cooler lines and the cooler for my GM 4T65E-HD transmission, because the transmission was overheating. The standard tip that comes with this doesn’t work well for GM quick connect lines, as the line connection points aren’t threaded, but I just bought the “universal tip” Kooler Kleen (O’Reilly Auto Parts only sells it) and used that nozzle, along with a make-shift seal. That worked well. My cooler was clogged with junk from the transmission which reduced the transmission fluid flow in the lines and caused the fluid to overheat; this stuff effectively blasted it out. I’ve used the solvent formula Kooler Kleen, but I don’t think it works very well and certainly not as well as this water-based version. This version is under much higher pressure to blast out junk in the lines and cooler.

Iโm hoping enough got pumped through my auxiliary transmission cooler. I shook can and while slowly depressing button as much of cleaner that was pumping through, an equal amount was blowing out the top of can at button. Not a well made dispenser!

Should come with assorted fitting for applications.

I’m not new to automotive repair. I bought this and a couple rubber hoses and bottles to catch the cleaner fluid.First, the adapter fitting didn’t fit my trans. Lines at all! Nothingvto adapt larger or modify onto the steel line. I tap into the rubber part of the line and still cannot make a seal. So I made a mess and had a difficult time properly flush, following directions. It seemed that if the can was PERFECTLY upside down, it will spray cleaner, not just pressure. I got it to work, that’s what matters
