mostly everyone has had this issue, the fix i had found to this is that, start ur engine and ppl normally say drive it for 5 minutes softly b4 any hard driving or anything but the actual fix to this is, start ur car and leave it there for 5-10 mins or until the needle moves up.

i found this had fixed all gear issues and everything. no more crunch, pop out, or anything.. so try it out.. it works

and driving it for 5 mins softly will do nothing.. so yeah
