tranny flush????
was wondering if a tranny flush is a good idea for a '99 4X4 superduty with 98k miles. The truck has never had its tranny serviced or had any transmission problems. I was told a flush at this stage would probably just break loose some sludge and gunk that would cause me many headaches down the road. Any advice or exprience on this would be greatly appreciated. Thanks in advance.

I did not choose to flush because I wanted to change out the filter and inspect how much junk was on the magnet. In my case, there was a lot of stuff on the magnet that I would have thought a flush might put it back into the transmission. I had 108,880 miles on the original fluid. It was pretty dark brown color. Looked worse than when you inspect it on the stick. Goog luck and Happy New Year.

All your doing in a flush is running the discharge oil from the converter into a bucket as it comes out of the oil cooler rather than let it return to sump in the tranny. At the same time you pour fresh oil in the filler tube. Do this until the oil going into the bucket is clear and red (About 16 Quarts). And you do that after the pan and filter change anyway. Oil is really cheap and transmissions are generally not. I would flush it every 50K

well, yeah i'd have it flushed i prob do 2-3 flushes a week. and it is really easy work with the right machinery, hook up the return and fill, drain, take off pan and take out filter, new filter, put back on pan, hit the fill button, done.. lmao it is easy, our machinery is brand new so all i gotta do is put in the vin on the machine and tells how many quarts the tranny will take.
thanks....
