Yes Eric. I think it was just the flimsy stock spring retainer which holds up ok in a stock application, but with a TF-2 one of the modifications is the spring behind the pressure regulator valve. The stock spring is removed & relaced by the 2 springs in the kit. This mod effectively raises line pressure & in reverse the pressure is regulated to max. Line pressure is almost 3 times that what it is in a forward range. Full pump pressure is applied to the rev/high clutch & the rear servo piston. Another thing is, the rear servo return spring in the TransGo kit is considerably stronger than the stock item. That is the reason I strongly advise changing the stamped steel spring retainer for a billet aluminium one. Heck! 30 Bucks is better than laying on your back with transmission fluid dripping in your face! LOL
