Not sure what to make of it, but I need to replace the fluids in the diff, transfer case and trans. But I was on the expressway and I needed to make it quick Lane change so I floored it, the truck accelerated like a monster but then it started what felt like skipping or stuttering from the transmission, not the motor. I did end up knocking loose my MAF sensor and I don't know if that would have been the issue. I had just installed my cold air intake but I didn't tighten the coupler connected to the sensor so it came loose while driving. Any thoughts or ideas on what I should look at or consider while I'm changing fluids? As always, any and I'll help is greatly appreciated!
