Hi,
The first thing I would check is the linkage at the transmission to see if things are still attached.
I attached a few pics below. Check these areas for damage, something disconnected, or a broken cable. When checking at the transmission, have a helper shift through the gears to see what is happening.
Pic 1 below is for a 5-speed transmission. Pic 2 is for a 6-speed transmission.
Let me know what you find or if you have other questions
Take care and God Bless,
Joe
