According to the guy doing my trans, my trans has (had) the mechanical diode. It's a 2001, V-10. Thought these didn't have them??

01-13-5***TRANSMISSION - 4R100 - DELAYED OR NO 2ND GEAR - DIAGNOSTIC TROUBLE CODES P0781, P0755 AND/OR P0756 - VEHICLES EQUIPPED WITH 4R100 TRANSMISSION WITH TRANSMISSION BUILD DATES BETWEEN 7/27/2000 AND 3/23/2001 ONLY

The above TB shows they did.

So what's the story??

 

Nope, gassers didn't have them. Ford only put them in the diesel engine rigs.

Hmmm...this is confusing.

 

When I worked at Ford we were told that all gasser trucks that were built with the mechanical diode had the trans replaced before leaving the assembly plant. I now believe that a small number of trucks did not get the trans replaced and a few mechanical diodes did end up in gasser trucks. It wasn't supposed to happen.

 

Thanks for updating, Mark. I was going by your previous posts when I answered this thread.

I will be getting all the parts that came out of the trans. I will know for sure tomorrow and put a pic so that way this can get put to bed.

 

recently my EX began shifting hard ...then the OD light flashed and the check engine light came on ... my problem was P0755 (shift solenoid B malfunction)... a new solenoid modual and $515.00 fixed the problem.......

 

Lucky for you man. I could deal with $515 as compared to what I'm paying for my trans.

 

the part was $320.00 ... then there was fluid and gaskets and labor

 

Same here. But now I have this pretty thing under mine:

 

Yep,our '01 Navigator and a good friend's '01 Lightning both had the MD in them. The Navigator had the trans replaced before delivery, and the Lightning was replaced during the warranty term.
