started posting on here recently trying to diagnose noise in trany on my 99 duratec... turned out to be front pump... which failed on ride to work today, cooked my trany, just ordered new jasper. I inherited this car from an old man, who drove it like an old man, and even with 90k on it looks and runs like it just pulled off the showroom floor. Only thing that bothers me is that when I got the car I tried to treat it to some love... including a trany flush... and "coincidentally" now I need a trany. I have friends that have driven these cars past 200k with NO love and here I am with my cherry ride dropping a trany b4 100k. Upon googling the benefits of trany flush I find a miriad of mechanics that warn against this process. Causes unnatural fluid flows under high pressure. My warning to you... we drive these old rides hoping to save a buck... think twice before 'flushing' anything.

I too have heard that.

*edit - Let me rephrase, I too have heard that flushing a transmission with high mileage can contribute to transmission failure. Weather or not the transmission was on its way out or not, who knows.

That is pure absolute B.S. Nobody has a system that has that kind of pressure to force
all the fluid out of a transmission in a flush. Who ever told you that hasn't a clue of what they are talking about. The car is started and the fluid is pumped out on it's own.
That transmission has a bad rap for a bad converter bearing. You had better SEE and be
SHOWN the bad pump before you spend money. Make sure you take someone with you
that knows what to look for and is honest. Mind you you could have a bad pump. It's happened before. Not very often but could happen. If your pump DID grenade and send
metal all over the transmission you will spend a lot more than $1000.00. Good Luck

I've just read that artical and never have i heard such shit. As i said in my post the engine is started and the oil is normally pumped out on it's own. NO back pressure and
NO reverse flow. How can you flush an engine and transmision in the same operation ?
Here is the best part. There is NO DETERGENT in A.T.F. If there was don't you think the transmission oil would show some signs of dirt or get darkened ? You know, as the detergent cleaning the transmission. Why does ATF stay clean after more than 100,000
miles. A.T.F. is the same as hydrolic jack oil with a red dye in it so you can tell the difference between engine oil, power steering oil and brake fluid. I use A.T.F. in my tractor's hydrolic system. As far as pouring a quart of ATF in the engine oil. GOOD LUCK.
That is an OLD wifes tail. Mixing oil viscosities and blends ! Not a good idea. Putting
ATF in an engine will sooner or later cause serious damage. If it doesn't make a difference why then is there an oil for the engine and a different oil for the transmission ?

Sorry Chip, there are machines out there that power flush. GM has issued a TSB warning dealers not to use them. They can blow out the seal on the torque converter.

That is probably why NONE of our transmission shops and dealer don't use them.
