Tranny shifting

[Dirtridertwo]

My 1997 powerstroke f250 is shifting stiff first to second but at a good rpm after that it seams to be shifting short some times and also quick and hard not shore what's going fluid seams good and it's not sloping at all but don't want any Problems if keep driving it like this

Also the more throttle I give it the shorter the shift seams to be if I run a 1/4 throttle it shifts perfict once a half or more simes to. Be short shifts

Mine does the same thing man I was reading on other forums on here for people having the same problem but it seems pretty common, it might just be that way normally I have a dump so I will see how it does with a load on I hear they shift smoother into second when weighted down

All automatic transmissions need regular fluid and filter changes ,Have either one of you guys done it ?
I strongly suggest a complete fluid and filter change including the torque convertor ,using the proper fluids .This is recommended by the factory every 30 k miles .
Believe me ,heat and debris from under serviced transmissions are expensive and unnecessary .
