It is some thing that has occurred to me. The first transformations of a character in the films take quite long compared to how long they usually take. For eg on TF 1 blackout took ages to transform in the airforce base and in the city he transformed when th soldiers were in the alley and it took literally a second . Why didn't he transform quickly first off ? Then in rotf ironhide takes a while to transform in shanghai I don't remember in dotm but if you do post ur reply I thought I would mention it to see if anyone else noticed ?
