Name that failing part!
I got my 2000 f550 in July. 226k on the clock, no record of tranny rebuild, I knew it would need to be done.
Last week I was driving alone and the OD light starts flashing for nothing obvious. Still shifted fine, sounded fine. Took her home, shut her down. Next day, same thing happened in about the same time frame, about 2 miles down the road, OD light flashing. Hoping to verify the issue, I unhooked the batteries to clear everything thinking if it's really starting to die, it'll with do it again. It does not, so I'm thinking whew and bullet dodged for now.
2 days ago, drove to the jobsite. My dad was there and his truck had a trailer on so he used my truck to run home. He gets back, doesn't say anything about shift problems, and I have to leave. a mile down the road I notice it's not going into OD. I'm getting that sick gut feeling knowing whats happening. Had a half quart of fluid in the back so I added it.
From there It doesn't shift into OD, it slips, it kind of makes a grumbling sound going down the road in drive. Taking off from a stop it made a grinding sound that sounded like the rear end went out even.
So I ask, is that the TQ, something a rebuild will fix, or something worse?
The fluid smells scorched now. There are no leaks, and about 3 weeks ago i did a quick fluid change. just dumped what was in the pan and put in some new to top it off. I did have about 1/4 cup of fine metal shavings on the mag in the pan.
So yes, I knew it was due, but I didn't think it would all go at once. In the past every trans I've experienced die did it slowly....
