Yes by all means warm it up before you move it. I let mine come up to
temp before it is moved far. I do move it out of the building to let it run.
One very important item. NEVER,EVER use high reverse. All ways use low
reverse.
Mine has ATF in it as well as the Memphis conversion manual shift
kit(REB) in it.You should drain the water from he transmission and remove
the front cover on the oil cooler on the transmission and clean it out Most
are full of trash and does not cool the transmission good.Heat will destroy
the transmission
