December 5, 2016I`ve got a 4l60e that i had built by Performabuilt and it`s got less than 3k on it and I`ve totally lost 1st! It`s not limp mode! I`m 100% sure. Manually I can get 2-3-4, lock up, everything works. But in OD it takes off in 4th. I can not get 1st anyway. Replaced both solenoids and checked 1-2 accumulator. Any ideas?
