well, as you know my AOD is going out. instead of a lentech i was thinking about getting a TCI. everything i could break has been relpaced with good stuf. one piece imput shaft, red alto bands, etc. etc. i can get it new for 1500 at my speed shop. he said it looked like a good tranny. same gearing as stock. if i get this, can i shift it 1,2,3,OD manually with a Ratchet shifter? or wil it stil go right into 3rd like a stock aod? is this a good choice??? THANKS!
