wth..no offense but why in gods green earth did you rev it up high enough in 4x4 low to get the trans to 260... 260!!!! jesus..
safe mark is 200-210...after that is catastrophic failure..
Id be saying you better go buy a trans..
DONT pull anything its not ment too...get a fully built trans...
What happened was the breaker that powers the fan on the aux tranny cooler failed and the fan quit working. Of course I didn't realize this until I noticed the tranny temp was too high. Immediately I rewired it to a fuse that was not being used so it continued to work. After doing so the temps hung around 200 and reached 210 maybe 215 a couple of times on the hardest pulls. The engine never really reved up all that much, just a steady hard pull for a long time.
I'll be the first to admit that I expect a lot out of my truck. I DO ask a lot of it, I pull heavy loads over tall mountains, haul loads of hay and lumber to remote "Back Country" locations that require a tough truck. Sometimes I have chains all the way around and bumper deep snow with 10-12 tons of hay on a 20 trailer. This truck is not babied. That being said, let me say that I am not complaining about the break down, just seeking advise on the tranny situation.
I had used Dodges up until three years ago. Always had manual trannys until now. I picked up the Ford because it had a full size crew cab and I have a large family. I like the PSD but these transmissions are not all that strong or forgiving.
I took the pan off today and found very little in it or on the magnet. Just some super fine metal. No brass, plastic, o-rings or large metal of any kind. Of course the oil was way burned. I'm going to do a flush and replace the filter and cross my fingers that I have not totally destroyed the thing.
Any other suggestions are appreciated. I still may need a rebuild, hope not.
Thanks for the info and advise.
Chained up for the last three or four miles on this load. Lots of mud!!
