5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I was talking to a friend of mine who is also a mechanic about how to keep the engine clean. He said if you want to clean your engine, you can replace a quart of engine oil with a quart of trans fluid when you change your oil. According to him, the detergents in the trans fluid clean the engine gently over time.
I've done this in the past (decades ago), but with todays modern oils you won't need to do this. In the past the lighter tranny fluid supposedly helped with sticky lifters. I also used Rislone and Marvel Mystery Oil a long time ago, but no longer do so because todays oils are very good.

I thought I was the only one old enough to remember pooring trans fluid down the throat of the carburator with the engine running to free up a stuck lifter. Boy did that make smoke.

I'm sure that pooring ATF through the carb, intake, combustion chamber, and exhaust would free up a stuck lifter...NOT! It's IMPOSSIBLE!
The only reason ATF is poured into the carb or intake IS to make smoke. There isn't any way that it could free up a stuck lifter when poured in that way...
Getting back to the original question, it depends upon the age of the engine and the sludge level. ATF is very detergent as you know and will clean out sludge pretty well. You wouldn't necessarily want to add it on a regular basis by the quart. More likely, add a cup full about 100 miles before changing oil if you just feel the engine is very dirty. If you have a sludging issue, be certain that the pvc system is free and open first and then add 2-3 cups of ATF to the oil, and then change the oil filter every 3-400 miles, adding oil and ATF each time. The ATF will free up a lot of crap so go slowly and change the filter often. No, this is not something that TRD is going to find documented in the Toyota service manual, but it seems to work over the last 50 years or so, so it likely will do no harm and can potentially eliminate a sludge problem.

Way back I had an old Ford Truck with a leaky Rad. and we had to drink all the beer and then pee into the Rad. to get home from the lake.

That is kinda bogus considering the lifters are not accessible through the carb, intake, or cylinder. Only way that would be feasible is if you dumped it into the crankcase....... I have however heard of using powdered laundry detergent, or comet to help seat rings. I would never do it, but have heard it works....

id just stick to oil in your engine honestly...we sell some additives at my dealership, and theyre made by 3M (fuel system cleaner, added in gas tank) and MOC (engine additive/protectant goes in oil)....i use them now and again but i doubt they really do much...
my engine looks brand new inside and all i do is change what needs to be changed at reccomended intervals....i do mobil 1 5w-30 synthetic every 3k with a toyota oem filter, seafoam every so often, and change trans fluid/coolant and always be on the lookout for leaks and the like...if you treat your car right it will treat you right honestly.
