No 5th gear

Driving home this evening traveling about 70 mph go to shift from 4th to 5th, 5th gear catches for about a second and then I hear a pop. No more gear... All the other gears are fine. You can move the shifter up to fifth and it feels like the gate is empty, nothing to catch on... thoughts, cost to fix? I had this happen to my XT, it was covered under warranty... Cheers.

Check with dealer - sounds like a familiar problem.

 

Seems to me that for some reason the fifth gear on the 5MT gearboxes is a bit sensitive.

 

And if you can't get that as a warranty fix maybe you should look into a change to a 6MT like the STi gearbox with DCCD. Just remember to change the rear diff too.

could be the shift fork is worn and poped oot

Now it gets stuck in gear too... A trip to the dealer next week...

That's not a good sign - that means that there are parts floating around in the gearbox, which definitely increases the risk of the gearbox disintegrating.

There must be a piece floating around in there, I took it back out again and now it shifts fine, still with no fifth gear... The Subaru dealer is only a few blocks away from my house. I'll ease it over there next week and see what the problem is... something tells me it's going to be a 1k to 2k fix, that's something I really don't need right now...

Any updates on this? ever find why you don't have 5th gear?

I'd be shocked if it wasn't 5th gear cracked in half, dropped, and is floating around the case. It gets stuck in gear, because half of 5th gear is blocking or snagging on the shift rails, which sit directly below 5th gear, right in the front of the second section of transmission housing.

Is 5th and rev on the same shift fork?

Yes.

 

Reverse has it's own synchro, though. It doesn't share the one for 5th gear.

I pm'ed the OP for a update on his SpecB 6 speed.

It's an 06 Spec B.

Yes.

I was just wondering what causes my car if you reverse its like the car will bind up enough to stop the car but not stall it.

 

I dont know when going to 5th you hear no engagement at all.. I want to take the rear off but is it going to be hard to get that shifter knuckle off?

I'd put money on the input nut having backed off in your car.

 

The knuckle comes off with a pair of punches (I don't remember the sizes). It's held in place with a double roll pin. Punch that out, remove the two rear sections, and you'll see the back of the input shaft. That nut is almost definitely backed off. Over the years, they kept increasing the torque on that nut (just like they have on the crank pulley). I THINK it's something like 165ft-lbs, but I am not 100% sure. You will need to get a new nut, and you'll have to properly stake it (just like an axle nut) or it'll back off again.

 

I'd rate that job a 6-7 (on a 1-10 scale, with 1 being mechanical noob, 5 being change your own clutch, and 10 being rebuild an engine). It's not HARD, but you can definitely mess things up a little bit.

The nut is 32mm right?

I believe so, but I honestly can't remember.

The same EXCAT thing happened to me. 5 gear split in to 2 pieces and fell of the shaft. i had all the other gears. eventually though, all the gears slid down the shaft and it jammed up the shifter forks and i could get the car out of gear. had to get towed.

It's an 06 Spec B.

 

Oh yea, 06's had the crappy 5mt.

 

Never mind....

 

Do you guy's think to check the Similar threads link at the bottom of these pages ? D_rock had a similar issue back in 08

Reverse is synchronized? hmmmmm

Yep.

I did a double take before posting too. I saw Spec-B, but had to confirm the year.

 

The 6MT is a completely different beast than the 5MT. If 5th goes out on a 6-speed, you have got problems that start with a $ and end with 4 non-zero integers.

on a 5mt, its yes and no. the gear on the shatft has a synchro, but it also has to engage a spur gear between 2 gears to get the reverse direction. this is not synchronized. this is why you cant always get it in to reverse when stopped and have to roll the car a little, or double clutch to get it to slip in some times.

There is no "no" about it. Reverse is synchronized. Synchronizers are completely independent from the idler getting jammed between two gears. They are mutually exclusive.

 

You can't always get the car into reverse, because the idler isn't lined up with the teeth on the 1-2 collar or the reverse scroll on the input shaft. That's not a synchronizer issue, nor could it ever be considered to be a synchronizer issue. It's a side effect of the idler design. Lining up the idler with the other two gears is not in the job description of a synchro. It's not what they are for, or what they do.

 

The 6MT has reverse on a constant mesh, where you select it just like any other gear. The NEW 6MT in the 2010+ LGT, has the same arrangement as the 5MT I believe.

How many miles on your '06? If you mentioned in a previous thread I apologize.

 

Good luck getting this problem resolved.

I made a little video.. hopefully I can open the transfer case tomorrow.. it seems like the hardest part will be just getting the selector arm to line up in the fork selectors?

 

Here is the video around 35 seconds in you can see the little jump in the shifter when I let the clutch out.

 

and at around 1:27 it's easy enough to knock back into neutral with just a finger with the clutch out.
