so here is the story:
I am trying to do the 3x3 with redline type F, and now i am just finished 2nd refill/drain. the flashing D has been there the first time i drained and refill + the 3rd & 4th pressure switches replacement. to be honest I do notice an improvement on shifting, what could be wrong? all help is greatly appreciated!

Recheck the connections at the pressure switches.

forgot to mention this: the Flashing D only come on when I drive past 50mph

I hate cars

I agree, check the switch connections. Did you unplug anything else? Only flashing at 50mph almost sounds like something torque convertor clutch related.

yes i did, i couldn't get to the 3rd one so i unplug a connector on the gold plate so that i could remove that plastic cover

D flashing means an internal issue with the transmission that could be a number of things. I suggest you go to the dealer and have them pull the DTC code for the transmission to help you figure out what may have happened.

If you want to try something else, make sure you installed the switches in the right locations (3rd gear in 3rd gear slot) and as well check ALL the connections around the area in which you were working. Also it might be a good idea to check the fluid level too, maybe that might be tripping the error.
