Modern diesels don't need/require to have auto transmission fluid to be dumped into fuel tanks anymore.
I used Diesel Kleen + Cetane Boost - it does not contain alcohol. I directly asked sales support from Power Service Diesel Additives. This will not "dry-out" parts in the fuel line.
Read this:
" Depending on the type of trans fluid being used, it has as little as 17% to as much as 25% chemical make up that makes it trans fluid. Most all of those chemicals will be bad for rubber fuel lines, the rubber seals in your pumps and bad for the metal contact high pressure components in the VP44 and CP3. Used engine oil is one thing as the add packages wear out leaving just oil. But many of the components of trans fluid doesnt leave the fluid and instead will get rather corrosive as they break down. Used trans fluid also will have way more wear particles blended into the fluid, both metals and frictions that engine oil wont have. Aluminum, brass, iron, steel, bronze, copper, plastics, teflon and metalized friction papers and ceramics in there. This stuff is so fine that it cant be really filtered out but instead will need to be re-refined. But its not fine enough that it wont cause damage to the pump, but instead will cause some severe scuffing. It will also bore out the injector nozzels with it being pushed thru them at such high pressure. Even on the P pump engines.
Just say no to trans fluid, ESPECIALLY used fluid!"
And
" There are also other problems associated with used ATF besides the contaminates, and that is these 'trans fix it' in the can additives that people looking for a magic fix pour into their transmissions. A lot of aromatic chemicals and seal swell chemicals are in them along with other additives that cause the chemicals to particpate sludge forming deposits. That stuff will cause sludge deposits in the tank.
Also the contaminates that do pass thru filtration, besides the abrasive effect, is most of that stuff doesnt burn. Instead it will bond to the pistons and rings, cylinder wall and combustion chamber and injector nozzels. When the engine is torn down for a rebuild, the tech is likley to say, "Oooh, look at all the pretty colors!" All of the trans clutch and band components use a bonding agent that uses high pressure and heat for the bonding agent to work. Perfect conditions for those in a combustion chamber. Nice way to permenatly bond the rings to the pistons and injector components together. Also the thrust washers and bushings are made with bi-metals and tri-metals that are bonded together using similar processes.
Transmission fluid also has a high concentration of detergents that cause ash deposits when burned. Modern day transmission fluids are either full syns using poly material (plastics, Herb knows the tech terms) or semi syns that combine polys and hydro carbon or a cracked hydro carbon base oil. These oils arent designed to be burned and dont burn very well. When they do burn, they produce a lot of soot that will blacken the engine oil quicker than diesel. An engine oil evaluation test will produce some very interesting results.
Burning trans fluid 25 years or so ago wasnt really a bad idea, before all of these new propriatory chemicals have gone into play, because the base oil was whale oil and didnt need most of the chemicals now that has to be used. It used to burn fairly clean. We used to heat our shops by burning used trans fluid in special heaters. Now when you try to burn the fluid, it clogs the injector and ruins the high pressure pumps in the heater. Deposits are a big problem in those heaters and EPA came down hard on their use because of the chemicals being emmited. Its hard to even find those heaters now, much less the use and building codes that prohibit using them. The heaters that you can find now will have a sticker on them that says, Use waste engine oil as a fuel. The use of transmission fluid will void the warranty. "
