I flushed my Transmission, now I have a loss of Boost and Top Speed??

[JDebus]

I flushed approximately 14-20 quarts of ATF through my Transmission and thought everything looked good.



Unfortunately, right after the flush on a test drive; I have a major loss of boost in each gear, -10PSI or more and the Top Speed is only 85MPH (used to be ~106).



This must be computer related... Is there any way to reset the computer?



Anyone understand this problem or how it happened, and most importantly: does anyone know how to fix it?

I also removed a body ground just long enough to attach a wire

Any help would be much appreciated.

You should fill in the info on your truck /sig , better answers with more info .
How many miles on trans ?
This where some bad ideals about flushing come in , its not uncomin that a tired trans get a flush & acts up , then what ground , if its one that goes to computer it may need reflash , a number of starts to reset .
