tomorrow i will be installing a b&m shift kit in my 700r4. this would be my first time doing something like this. i have read the instructions already and they seem pretty detailed. is there anything i should know or watch out for before i attempt this? are there any particular parts in the process that are particularly tricky? i have watched the trans guy at my work tear apart and put together a few 4l60s so i have an idea of what im doing but any advice would be greatly apretiated.
