I have an issue awhile back where I couldn't shift passed 2nd. Took the car in and had the transmission rebuilt. Lately, when I first hop in the car and take off, it will miss 4th and go into neutral until I let off the accelerator. Second I left off, it catches and shifts to 4th. Also, if I'm in 4th and get on it, instead of shifting down it misses and goes to neutral. This just an issue with a poor rebuild?

 

made to shift out of overdrive under heavy acceleration from factory = lame

 

Sounds like the Input sprag is letting loose bet it dosent do it in D3
