the truck is a 2012 f250 6.2 flex fuel from alberta canada.this isnt the first tranny form out there that ive heard do this .just wondering if any one else has come across this and why they do it.tranny seems fine shifts all right just a whine while accelerating

 

How many miles are on the truck and when was the transmission last serviced?

 

my 2012 with 138,000 miles had its transmission fluid changed at 50k and 100k..
and I will do it at 150k..

NO NOISE...

 

are you sure its the tranny. my 2010 f-450 has a whining noise, but upon putting it in neutral going down a hill, it still whines so I'm thinking its my semi-truck style tires.

 

150k on truck not sure when the last service was its at a used lot i was looking at it today. it only whines under load but its not the first truck from western canada ive heard doing this

 

Point it out to the dealer and see if he'll service it and give you a longer warrantee on the tranny. I haven't heard one whine. Maybe a Canadian thing. LOL

 

that is actually what i was thinking as i said it isnt the first one ive heard do this from western canada

 

125,000m Alberta born 2011 with no transmission 'whine' here. This wouldn't be the first time I've heard about whiny Albertans though.
