if its the first time you serviced the tranny then it should be alright with the mileage. how does the fluid look?

 

it smells burnt

 

is this the first time the tranny is being serviced? a flush may help it but i dont know if it'll fix it.

 

it is the first for me but i only bouht it like 15000 miles ago

 

its entirely up to you what you do. i've seen flushes save transmissions but some vehicles it doesnt always work out. the 4r100 depending on the cooler and radiator takes 18-20 quarts of fluid so it can be a pretty expensive flush depending on who does it.

 

If there's metal in the pan and the fluid smells burnt, start looking for another tranny.

 

That is natural after that many miles. Take the pan off and clean it, then put new fluid in with a new filter. That should be good to go for another 100K.

 

Burnt fluid is not a good sign though.

 

does it have to be out of a superduty and the tag on the tranny how do u decode it

 

Yes, it has to be out of a Superduty.
