Hoping for a little help from anyone. I have a NAG1 transmission that shifts fine in every aspect, except when it goes from 1st to 2nd. When it shifts it slams really hard. It almost feels like being rear-ended. Any ideas out there?
I'm not familiar with that nag1 transmission but does it have the ability to shift manually? Just curious if it does if you shift it manually rather than letting the valve body do the thinking does it still do it? Just curious.
