Sorry at work
The reason I posted the gmt400 was because in the video it’s an external part issue. Because I’ve had so many people say it’s time to replace the transmission. So I was hoping it may be an external part like on the olds. Now what it will do is drive and shift slowly, however, from a stop it definetely is hard to tell if you shift it into gear as it does seem a little weak. Fluids were good. But yeah going into a garage from a slow speed it seems to struggle over the entrance lip, and sometimes when cold can struggle to get going into gear. It’s at the shop right now and they haven’t had much time to look at it or work on it, but they informed me of the issue and aren’t the first to. I’m asking what problems could this be on the external side so I don’t have to pay for either dismantling or purchasing a new transmission. I know my explanation sucks I’ll give more feedback as it’s available
