Shifter Popping Out Of Gear

[raz0r$harP.UK]

Hi guys,

RB26, JB clutch and stock flywheel

- Car has firm (but not overly hard) suspension

- Bit of a resonance issue at cruising speeds (from exhaust)

- Shifter will pop out of gear after about 5 min on the highway, or bit earlier if the road is a bit rough

What should I start looking at to fix?

Cheers...

rx7 owners have this problem when their synchros are on their way out or if they have 500 hp.

shifter pops out while you step on it.

i had the same issue but was my 1st gear, bad news for you is that u will either have to pull box down or get another one,

If it happens when you back off more than likely you have a worn gear ( the one that pops out)

mine pops out of the tops gears, i have removed the gearboot and it helped for a while, but it still does it does that means the gears are destroyed? it maybe the 300rwkw goin through it though lol....

Does it pop out in all gears or just one or two of them?

Your synchro hubs sound worn to me. Will need a recondition + replace synchros.

it happens in 1st 3rd and 5th, but 3rd is the gear that is the worst... 1st and 5th rarely...

Yer you'll be looking at replacing the synchro hub assembly mate...won't know for sure until you pull apart the box but those are the symptoms that usually go with it. In a way it's good because there's no bullshit bandaid solution like using a different grade oil to silence problems, forcing you to repair it properly hehe

could it be worn detent springs/balls or the grooves in the shift rails?

[Birds]

Nah not really, they only serve as way of selecting the gear. The synchro hub and the gear itself hold it in

thanks for the help fellas, how much would this prob cost to fix, i need a new clutch anyway....

[Birds]

Bout $1000 to recondition it mate, plus the labour of pulling the gearbox out / installing it again. Oops, I just realised you aren't the OP that I originally addressed my questions to lol. Same problem anyway...
