Default Hard Shifting Automatic

I ended up driving a short distance today with no MAF, I just plugged up the hole. It drove just fine but when the trans would shift from 1- 2 it would be so hard it felt like I had wiplash. This was significant to me because the truck has been having hard shifts for a while, just not this hard. Its almost like a miss fire but I have no codes and it only happens when the trans is shifting. Any idea on what could cause this.

Default Re: Hard Shifting Automatic

The transmission relies on info from the MAF sensor in order to get it's correct shift strategy. Without the MAF sensor plugged in, the transmission control unit basically puts the transmission into limp home mode. I would not suggest driving the truck like this, as you could cause damage to the transmission.

If you're experiencing rough shifts, then I suggest a fluid and filter change. I highly suggest opening up the old filter and inspecting the filter element for rubber gasket material. Reading the trans filter element provides great insight into the condition of the transmission.
