2004 F150 4.6L Transmission question Help please

Okay, let me start off with I did use the search options and couldnt really find my exact issue.

I just bought a 2004 F150 STX 4.6L V8 with automatic trans with 57,000 miles.
I love the truck. However, I just noticed yesterday that in heavy traffic at very low speeds (constant stop and go at low speed between 10 and 20 mph) that the truck at one point seemed to slip out of gear.

In other words, it seemed like the truck shifted into neutral just revving when pressing the gas (again, this was at a very low speed so I dont think it was OD problem like I read about) The truck did not show a check engine light or anything. Once I let the truck rev settle back down, I was able to drive it again. I've had the truck for about a week now and this has been the only time it has happened.


Any ideas? Has this happened to anyone else? Any help or tips?

**when using the search option, I read in several places that the 5.4L truck having a similar issue, but with the trans going into neutral just before shifting into OD. So I dont think my problem is related since mine is a 4.6L and it only happened once and that was at a very low speed as mentioned above**

Any help or advice is greatly appreciated
thanks,
Josh

Josh I would check a few things. Check the dipstick when the truck is hot idling in park after driving a few miles. See if the fluid looks dark or smells like its burning. Make sure the fluid isn't low. If the fluid it hasn't been changed which I bet it hasn't it's due. I bought mine at 45,000 miles (now have 75,000) and I've noticed that between 20-30 mph the truck slips out of 4th and into 3rd sometimes but I don't notice a loss of power.

i drove the truck not long ago . it prob sat for about 15 mins. it was still warm so i pulled the trans dipstick and smelt it. i dont really know what burnt fluid actually smells like but it smells okay i guess. u could tell the fluid smelt warm but i dont think it smelt burnt. however the level seemed kind of high. the fluid was above the hot level marking in the do not add marking. the fluid looks new too. i bought the truck at a dealership so it looks they servised it new oil, trans fluid, etc. etc. could the level being high cause the prob? the truck has not done it again but its still in my mind.

The fluid should be checked hot and with the engine running. I would contact the dealer since you just bought it and see if the transmission had been recently serviced. If it has been serviced there is a possability that the filter is not seated properly.

Millzy's right, the reason it needs to be idling when you check it is so the pump is operating which will drop the fluid on the stick a bit. Yeah you should check to see if they have it on record of the change at the dealer. If it only happened that one time I wouldn't worry about it unless it comes back. If the dealer didn't change it I would at least drop the pan, change the filter and replace the 5.5 quarts. Or you could do the system flush method after replacing the filter, adding the 5.5 qts and getting the rest out of the cooler lines on the front, just for the peace of mind.

Here is a link for info on the flushing method if you want to do it yourself: https://www.ford-trucks.com/forums/6...-schedule.html

Bad tranny fluid may not necessarily smell burnt, it can have a sour/bad odor.

Is it possible to syphon tranny fluid out through the dipstick tube and replace with fresh fluid?

Yes.

Many of us "home mechanics" install drain plugs or replace the pan with one that has a drain. That makes future fluid changes less messy...and thus, more likely to occur.

Every once in a while mine truck seems to slip between 2nd and 3rd gear for a brief second. I also have a slight misfire when idling. No check engine light. Haven't put a scanner on it yet. Could a misfire effect the shifting?
