Looks like I lucked out and won the transmission lottery.

2011 XLT 5.0 142,000 miles.

Pull out of work tonight, and 1/8 mile down the back street starts shuddering and instruments go wacko.

So I pull over, shut it off, restarted it, and didn’t get 100 yards before it did it again.

Shut it off again, restarted it, got on the frontage road, acted fine until it downshifted to 1st from 40 mph, the wrench lit up, and it kicked out of gear.

So I pulled over, started it up, put it in tow/haul, and it acted fine until I got home.

I wasn’t going to do the reflash, and I’m not convinced it will help this.

Am I looking at a transmission rebuild?

Any advice ?

 

I'm thinking leadframe and/or VSS.

 

Sounds like a lead frame issue. Do you have forscan? You can determine yourself if it’s the speed sensor. There is a recall on this part but I’m not sure if 2011s are covered. Fairly inexpensive to fix yourself.

 

You should be covered under the leadframe warranty extension. Check your VIN, I suppose, but the original from a couple years ago was 2011s and 2012s.

The reflash recall stops it from dropping into 1st gear, but it doesn't solve the actual problem.

 

Mine is a 2011 5.0 and they just did the lead frame upgrade on mine as part of the recall. I have 100,000 miles and never had a problem or code

 

I made an apt for Friday AM, and the Blue Ox can sit in the driveway until then.

I mentioned the extended lead frame warranty, and I'm not going to let them get away with not changing the part.

Software won't cure this problem - it's obviously parts

 

I dropped it off, and they called me back and verified the lead frame was bad, and that they would have it finished Monday.

Im losing my 5STAR tune, but it’s not their fault my SCT Tuner is bricked.

 

*Update*

I picked it up - Ford covered it under the extended warranty.

so as a lagniappe I got my transmission serviced, because they had to drop the pan to get at the lead frame.

It drives fine, shifts fine, and the transmission temperature sensor must be included on the lead frame because the temp gauge reads lower now.

The only bad part is losing my 5STAR Tow/Perf time.

The shifting is softer again, throttle lag is present again, and my days of being able to pass at high speeds is gone.

Oh well - I had a good run with it!

It’s better than paying for a transmission repair.

 

Worst case it only costs $150 for SCT to fix the tuner. And 5 Star should be able to email the tunes to you again if you don't still have them on your computer.

 

I've got an email to 5STAR, because others have said that the reflash .changes the strategy, and that they couldn't get into the ECU's again.

I don't mind buying another tuner, because I had a heck of a good run with the last tune - 100,000 plus miles!
