Periodic Cold Transmission Failure
Periodic Cold Transmission Failure. My 2008 6.4 diesel F350 has 165,000 km. problem started last October about 20k ago.
Only when cold, it occasionally fails to fully engage. I start up, put it in Drive, and step on the accelerator. It revs, but fails to go, I'm just kinda coasting, as if the clutch is totally worn out.
This only lasts a minute or two, then it starts acting normally. Interestingly, I was using a diesel Dodge 3500 for a short time last year, which was doing the identical thing, again only when cold.
Took mine to Ford mechanic, they could not replicate the problem or get any codes. Anyone know what's going on? It's getting more frequent, like a few times per week.
