I agree not quite the same but it gets the fluid pretty hot, and it also gets dirty, guess this is one of those times we agree to disagree. would that be a another time warp thing, ha ha.
For sure!
But that is why I looked at and sniffed the tranny dip stick. (keep it clean you guys!) If the fluid was dark and smelled burned. I would have went for the flush. I went about 90,000 miles on my Bronco with AOD and had been in the mud and 4WD the heck out of it. I pulled the tranny dipstick and it smelled really burned and was dark brown. I flushed it but didn't let them use any flush chemicals just tranny fluid. Worked out great.
In Central Texas I found Mercon SP at a local parts house that is owned by Arnold Oil company, a local distributor.
The 30k maintenance only calls for a drain and fill and external tranny filter change. The flush is extra and not necessary. I did the drain and fill. It took 8.25 quarts. I know a local trans shop that won't do the flush.
I think the reason that some don't recommend changing all the fluid is that atf has very high levels of detergent (probably common knowledge here) and all replacing all the fluid will remove built-up varnish causing increased tolerances that could only lead to no good. My personal opinion on automatics is if you are going to flush, do it more often than prescribed preventing or at least slowing normal wear & tear and varnish buildup from the get go. I don't know if it was SB ot KW that rotates between flush and drain & fill but I like that idea for these high tech tranny's. If I am going to overkill on fluids I will do it there b4 the oil (I do it there also) because I love the truck!
I can't confirm this, but a guy at the local trans. shop told me that if you change the tranny fluid too often the detergent eats up the clutch plates.

I once had an F-150 that was a really good truck. I loved it until I had the tranny flushed at 75k. A week later it started slipping and I barely made it to a pay phone before all the fluid came out the bottom popping and hissing as it hit the wet ground. Naturally, I was on a rescue mission to pick up my wife, kids and in-laws as the wife's Nissan van had lost it's fans and overheated 40 miles from home and was now awaiting repair. After getting home I discovered the heat pump had thrown craps and needed repair. Three grand plus in repairs in one day and the in-laws were still there. Among other things, I suddenly hated that truck!
Of course, after the fact, several folks pointed out that I should never have flushed the tranny at 75k. I should have done it sooner or not at all. Jeez, I just love all the advice as I write the check...

Fellas,
A couple quick questions regarding my transmission leaking fluid. I have a 2005 PSD FX4. I just recently had my transmission serviced out of town. When pulling a trailer, I noticed a lot of fluid coming from the transmission. I can not tell exactly where it is coming from. My understanding is, there is a vent on top of the tranny that will release excess fluid. I am assuming it was overfilled. When checking the fluid level, letting it cool overnight, the dipstick still shows it to be full. THis has happend several times, but the stick continues to show that is is full. The truck runs great, other than the fluid coming out I can't tell that there is a problem and this did start immediately after it was serviced. Questions are,
1. Will having the excess fluid harm the truck? Or does the overflow vent correct the problem by default?
2. Do yall recommend starting over? Drain, flush, and put back in the correct amount?
3. Ok ,the manual calls for MERCON SP. The guy at the local transmission shop (not the one that serviced it to cause the problem) said he does not carry regular MERCON SP but uses the synthetic version. Does MERCON SP-"Synthetic" exist, I haven't found any info on this? Or is MERCON SP already a synthetic and the fella is just confused?
Any input on this one would be greatly appreciated. Thanks
