something to consider,

the "D" on my dashboard has been out for months. i cleaned the switch underneath the shifter, by the tranny, when it first happened. it was dirty, now its not, and the "D" is still out on the dash. so i figured the bulb must be out. and there was not any odd shifting problems in all that time.

my power mode light has been out for around a month, before this all happened. the winter mode still works fine, and the winter light on the dash works.
the truck feels like it is in power mode, even if the dash light doesnt tell me so. so again, i figured another bulb is burnt.

fluid in tranny was checked this fall, and was right where it should be.
a change and filter has been on my to do list. but i got alot of other list also.......

i just feel like something happened when i lowered the tranny down that bit.

thanks for the input thus far. i cant stand being this close to driving again. the things i was worried about, (timing, timing belt, etc) went so smoothly, and the thing that wasnt really even on the radar, is giving me fits.
thanks again!
