Having throttle problems when pulling heavy load

Im having problems when im pulling up hills my rpms start surging up and down when im flooring the gas pedal but when I barely press it the truck drives fine I changed fuel filters air filters had injectors done last year I have a code MID 130 PSID 27 FMI 12…. But the code comes and goes only when I floor the gas pedal I know it’s for the clutch in the transmission also I have no check engine light any body had this problems can you help me out transmission is a IShift

Yeah everything stays the same just rpms goes up and down but it seem like I’m loosing boost also when I’m climbing

 

I do have a oil leak around that area and I never got a check transmission warning and I have 753208 miles on the truck but sometimes the truck would go to “L” mode when I put change to drive I would have to turn off the truck and restart it to go back into “e” mode but that haven’t happened in a while
