I have a 07 f150 5.4 supercharged and today while driving to work i notice that the transmission was not shifting to 4 gear which is overdrive,..in WOT but normal driving it will,..also if I do it manually, it shifts with no problem,..the problem is only at WOT,..does any one know what the problem can be? I have an Aftermarket converter that I bought from Troyer Performance, its a 2800 converter. I checked the fluid and its good,..I smelled it and it doesnt smell burned or anything like that. If any one knows whats the problem let me know.

 

anyone i really need help!!

 

Bump

 

What's the highest RPM you have seen at WOT in 3rd? Is the ECU stock or do you have a programmer or tunes?

 

I have troyer's performance tune, and the highest rpm's is 5500 But I have to let go to the throttle in order for it to shift

 

You need to contact Troyer. Something is not right with your tune, the 3-4 WOT shift point is not set correctly. You haven't been playing with any of the parameters, have you?

 

I already did and they said it had to be something mechanical, since I haven't change my tune, and I have to agree because it wasn't doing it, it barely started to act up!!

 

Sounds like a tune issue to me. I'd make Troyer look look the tunes over.
