Think tranny is going out

[mwalls54]

back in november i towed a small load 1000 miles and the tranny started to make a humming/shutter noise in 4th gear. well it was about time for the full tranny flush 79k miles. I did that right before I drove home for christmas. I left the next day towing about a 9,000lb trailer from kansas city to virginia. First 500 miles was black ice so i didnt get the truck up over 50mph. Once the weather broke I was able to run 70ish and over the last 500 miles the slipping and shuttering got worse when crusing and down shifting from 5th to 4th. I was going to tow my trailer back loaded but the tranny woudlnt' let me.
It dosent' slip on hard acceleration but only crusing and part throttle. I checked the fluid and it smelled burt and tasted burnt too So i am guessing the cluches are getting burt up in 4th gear. before i headed back to kansas i drained the pan and put some type f fluid in to put a bandaid on it. it worked for a few hundered miles but it came back.

sounds like it`s toast........if you do end up R/R trans, make sure the trans cooler and lines get flushed out really good....

I havn't made it up that way yet. might have to wait till it gets warmer. Is that a dmax I see in your picture???

I have to figure out whats going to be the best route. Reman from ford or a built one.

if you can afford it, get one built....may cost more now, but should last longer if built properly. plus sounds like you do a fair bit of towing....JMO

Well I still havn't done anything about the tranny yet. Out here in flat land it dont seem to slip. but this morning when i came to a stop the speedo said 11mph and would pick up as i moved. I wonder if this has anything to do with the tranny going out?

The speed sensor is in the rear differential. There are a couple of wires going to the top of the diff and THAT is the speed sensor. They do go out and give faulty speed readings.

well ended up having to put the truck in the shop because i noticed oil coming out around all my boots on the boost side. It appears it was my turbo the whole time. Dealer rebuilt it under warranty and so far everything is back to normal.

Good to hear. What happened to the turbo? Glad to hear all is well and you are not out any major cash.
