I've been having this issue with my EG4 hatch were 2nd gear on occasion pops out either during 1st to 2nd shifting or shortly after the gear is engaged. I do have a short shifter that has been fitted by its previous owner so I have no idea about the specs on that but my suspicion would be that its related to this issue. Its a very temperamental problem as well. I can go a whole day without it happening and on the other hand it can happen at almost every shift.

The other obvious thing could be some sort of transmission issue. All the other gears are fine and sound healthy without any grinding or popping out issues. I'm still trying to source were the issue is coming from so I can take action accordingly. Any insight on this would be greatly appreciated.

1. Check the shifter linkage that go to the transmission.
2. Bad denten springs
3. Bad gears or shif rail/fork

 

Do what Ang008c recommends. I would guess you have a worn 2nd gear, which means rebuild time (synchros, bearings, 2nd gear). Probably not what you wanted to hear.

 

S20 should mean aluminum shift forks which don't typically bend, instead they break. So it would most likely be worn 2nd gear. Kind of a common gear to take abuse with street racing as that is the one you are slamming into gear at redline most often on the red light take off race.

 

Thanks for the help guys. Hoping I can get it resolved soon.

 

It wouldn't be hard to find a OEM shifter and replace the short shifter, Short shifters put extra stress on synchro's etc. Easy way to rule that out! If it still pops out pull the trans and have second gear inspected/ replaced.

You can try installing new or aftermarket detent springs which might help keep it in gear if its a worn out detent spring, these are very cheap and easy to install!

 

Any links to the aftermarket detent springs? Would like some stiffer ones to firm up the feel of the transmission in my car.

 

I'm using Speed factory ones but i have a B series not a D series,

Any idea where I can get OEM shifters online?

 

The shift linkage? i think Innovate and Hasport sells aftermarket ones but OEM shift linkages are discontinued, i bought one from ebay a few years back but hes sold out now, its similar to this package but this is for a D series but the OEM shift selectors are hard to find new.
