Good day. I drive a 2004/2005 VW Polo Classic 1.9 TDI 5 speed. My Polo recently started with an oil leak on the gearbox after I had the CV joints replaced. On my way to the auto parts shop to buy gearbox oil, 3rd and 4th gear struggled to engage and made a grinding sound. I did not force the car into gear but decided to pull over and stop. I then pulled away again and when I wanted to try and select 3rd and 4th gear, it was as if the were never there. What could have gone wrong?
There are several possibilities:
- the selection mechanism at the gear lever
- one of the cables or links has stretched, broken or disconnected
- the selectors and interlocking detents in the gearbox are out of alignment
- the synchromesh assembly for 3&4 is damaged, seized or breaking up. Further investigation needed
