I have a F-150 5.0L with 90,000 mi. The tranny comes out of gear driving at a steady speed. No pattern, weather makes no difference nor does speed. This may happen within first 3-5 miles and may not for 200-300 miles. Left it with repairman for a week, he drove it every day and it never came out of gear while he was driving it.
Any suggestions?
Hi sansbois, and Welcome to FTE! Please take a moment to check out the Guidelines as they contain important info that you'll need when posting on the site:
What year, and what engine and transmission? With the info you gave us, all we can tell you is that something is wrong. Give us more info and I'll bet there will be some suggestions.
His public profile says it's a '94 and he originally posted in the small block forum so I would assume the engine is a 5.0. That should make the tranny an M5R2, I believe...
Did they use the ZF in the F150? My sources say that it was used in the F250 and up...
It was used almost exclusively in the F-250 and F-350, but a few very rare 1988 F-150/Broncos were made by Ford with a ZF. It's safe to say that 99.9% of the F-150's out there with 5 speeds have the M5OD.
I have heard that when a manual tranny pops out of gear like you're describing, it's rebuild time. But I haven't driven a manual tranny that far yet, so I'm just repeating what I've read before.

Casey, the pickup with strange tranny is '94 F-150 5.0L auto transmission. going a steady speed the tranny will come out of gear. I let off the gas and the rpm's will come back to normal and then everything is fine until it decides to do it again.weather makes no difference. neither does distance. Ford dealer says they will have to keep it
and drive it till it does it's thing. One mechanic drove it for a week and it never came out of gear. Got any suggestions?
Change the Transmission Range Sensor (TRS.) It is sometimes called the MLPS, same part, different names.
The TRS is failing. Until it dies completely it won't set a code. While it is failing it will sometimes tell the PCM that you moved the shifter to N. When this happens the computer will shift the trans to N. That's what you are seeing.
