That's what happens when you let idiots build you a trans.....
Or you have the orc removed....
The 400 is heavier then the 727, not a little either...
I use A&A and MSperformance for my trans issues...
They see over 800hp, not even a hiccup, Rick did my 727 which was the 1st externally adjustable 727... that was over 10 years ago... that trans sees over 780 on muscle and then another 2 stgs....
Go to a mental patient and or places like tci and similar crap and then you'll have issues..
