1989 4l60( 700r4) shifts from 2nd to neutral
I have an 1989 4l60 (700r4) and from time to time it shifts from 2nd gear in what i would describe as neutral. I have rebuilt the transmission and it has parts of a B&M shift kit and a Transgo shift kit in it. 95 percent of the time it functions just fine, shifts quick and hard through all gears. When i do have any problems it is the 2-3 shift and my foot is in it, i'd say at least 80 percent throttle. All i do to fix it is i let my foot off the gas and it slips into gear and away i go. It tends to have problems more often when it's cold. I'm not overly concernd about it, but i'd like to fix it. Kinda make me feel like an idiot when i go to pass someone and it shifts into neutral and just revs the engine haha
If anyone has any ideas or suggestion i'd like to hear them.
