Transmission fluid in with gas

Is this a rumor or is it for real:
Adding transmission fluid to your gas help clean your engine. A mechanic friend said he does this once every five tanks.

Anyone ever heard of this? Has anyone ever done this?

I don't buy it. I've heard of using synthetic ATF for power steering fluid (coincedentally in my 97 Saturn) but not in the gas tank. Only thing i'd put in my tank besides gas is techron.

ive heard of this many times but have never tried it, although i think my dad did this for a while but then stopped for some reson.
maybe because it doesnt work, or maybe hes just lazy lol. But if you want you could give it a try for all of us and tell us if it kills your car lol:lol: And if it helps THANKS!!!

It actually does work, trans fluid has so many cleaners in it it will clean the hell out of your engine for sure. I actually put half a quart into my CrankCase about 500Miles befor my oil change, it's sorta like SeaFoam but cheaper.

Just did this with my 96 Buick PA and what i did was a put in 1/2 in at half tank and toped the tank off then i put the other half into the crank. Everything works perfect and this was done about a week or so ago and im down to about half a tank * dont do much driving *

Good Luck

so what about the o2 sensor? wouldn't that cause it to become damaged? how much trany fluid do you put in each tank and how big is your tank, Marsal?

I only put in one bottle of it at half a tank then fill the rest up. And, im not sure of the size of my tank.

Indeed it is true, transmission fluid does helps but I think, old cars don't need much.
