The trans on my 2005 5.4 4x4 has started slipping. Is there any band or other adjustment that can be done on these?

Would this be the 4R75E trans?

 

Yes, it's a 4R75E. No, there are no adjustments on the transmission.

 

Thanks Mark.

 

When was the last time you did a complete fluid exchange?

 

Even more importantly, have you had a pan drop and filter change? That IS the factory recommended normal service as opposed to a fluid change which is only recommended when the fluid is visibly contaminated.

 

About a month ago had full trans service done. Pan, filter, converter flush/fill, and general check-over performed by dealer. Unfortunately, looks like that was wasted money at this point. 150K on it so not completely unexpected but still kinda disappointing. My 94 F250 that I've beat to hell and back hauling many tons of rock and everything else has a lot more miles on it and it's still going strong (knock on wood lol).
