Automatic Transmission Longevity
Hi! I am haven't posted to FTE in several years but am looking at buying my first powerstroke and I had a question for all the automatic tranny owners out there.
Either, how many miles do you have on your auto without any major trouble/rebuild or how many miles did your tranny go before major trouble/rebuild?
Any info on how much towing you did and at what weights would be helpful.
I am trying to decide between auto and manual.
Thanks in advance for any info you can give me.

I've got 196,000 miles on my stock E4OD now, and never even flushed the fluid out. I haul trailers regularly from about 5k to 14k and have never had a problem. I think a lot of it has to do with the program in the computer and how you drive it under a load. I definitely suggest a trans gauge to watch the temps, but at 6k lbs I don't think you'll have any problems.

165,500 on my 99.5, auto. Has pulled cattle trailers off and on and has always had a conversion tank in the back. My next one WILL be a manual no questions asked. Major torque difference. Auto's are more sluggish when starting out.

94,500 on my stock tranny and had to replace TC/Tranny/Input shaft seal on Transfer case. No trailers, just highway miles. Should not have had to replace it.

My 99.5 has 140,000 on it. I bought it used with 86,000 miles and as far as I know it still has the original tranny in it. I pull from 4,000 to 12,000 lbs 4 or 5 times a month. I did change to synthetic tranny fluid shortly after I bought the truck. I also have a set a gauges for the tranny temp.
Good Luck!!!

I have 107,000 on my 96 and it starting to slip a little on take offs. I do pull, on occassion, a 12,000 lb. fifth wheel. I guess it time to start looking for a tranny. I wonder how many more miles I can get out of this tranny if I don't pull anything and keep my foot out of the throttle???

If you want a Auto tranny to last a long time; the 2 following things are a must:
1. Tranny temp gauge.
2. Proper flush intervals.
If it doesn't already have a tranny cooler, you definately need to get one. (All SD autos get one regardless of engine)
Heat is the #1 killer of a Auto, thus the need for a tranny gauge.
You change your motor oil, right? So why not change the tranny fluid?
A properly maintained Auto can out last a motor or two.

heavest weight in was at 26k and change, combined weight of truck and trailer.
maintenance: regular fluid change every 30k.
