RPM fluctuation after 4L60E rebuild.
All,
I just had my transmission rebuilt (sun shell broke, Beast sun shell installed and 5 gear planetary installed instead of 4 gear along with all gear packs) and we installed it with no issues at all. Only things I'm noticing that seem off to me are the following. When I got to take off, it seems as if I have to reach about 1300 RPM before the full power actually kicks in. Everything is fine after that until I get to OD. Once I hit around 45 and up on the highway, I see a 200-300 RPM fluctuation up and down. Doesn't feel like a downshift at all. Just a fluctuation of some kind. I don't know what it could be. I have been all over some forums and do not see this exact list of issues. It could be two separate things that I need to look at. Just need some help to push me in the right direction.
