833 4spd repair advice

Well, any progress.
Hope it wasn't to bad.
Anyone who claims to have never screwed up, didn't try hard enough.
Apparently not much damage was done after my transmission was inspected by the guy who rebuilt it. He says he always lubes it up pretty good and even throws a little oil in.
Apparently the reason it wasn't going into 1st was because there is a linkage that closes off first and second when reverse is engaged and it wasn't disengaging.
Had the trans reinstalled....now it doesn't go into 1st again....
Called him up and he suggests I simply have to adjust the linkage to get that reverse to stop closing off 1st gear...
So, to answer your question lol....it looks a though I am not out of the woods and will know a lot more about 4 speed transmissions when I'm done doing it myself...
Pray for me lol
