corvette servo 4l60e and what else after cam swap

I've done a little bit of reading and found this on another forum called chevytalk about common issues with the 4l60e and these were the only ones that it seemed similar to. I have noticed it shift from 3-2 before, and on occasion it has shifted from 1-2 after crusing along at about 20 mph for almost a full minute in 1st, but in general it is completely resisting shifting from 1-2. Last night I tried a little WOT in 1st gear and once I hit redline (around 6k at 55) the engine just continued to stay at redline it would not shift into 2nd. If I'm leaving my neighborhood at light throttle, it revs up to 3-4k before shifting into 3rd at around 30-35 mph. I think I have a pretty decent idea of how it's acting now, but not sure what may be the problem or how to proceed.īasically it seems like my truck does not want to do a 1-2 upshift at all. This problem has been going on for maybe 2 months, but I drive my truck so rarely that I never had much time to troubleshoot it or figure out the symptoms. Been busy with 2 jobs and school, but since I'm on Christmas break I'm trying to figure out this transmission issue before I go back for the spring semester.
