5th Gear Disengagement

Recommended Posts

Hey Everyone,

On searching the web and this forum, I can find the issue I am having in 4.1 and 4.2 models, however I'm not finding much on it occurring with the 4.3 generation. I have a 2009, petrol, 2.4 l, 5 speed manual, Rav4. 

The issue I am having is that 5th gear won't stay engaged (it'll pop out to neutral) when power applied unless I hold it in with my hand on the gear stick. From my searching, I can see this was a common issue on 1st and 2nd gen gearboxes. So I have a couple of questions for more knowledgeable folks:
 

  • Is the gearbox the same on the 3rd generation Ravs as is on the 1st and 2nd? I.e. 5th gear can be accessed with dropping the whole transmission etc
  • Has anyone with a 3rd gen Rav also had this issue?
  • Will the fixes posted for 1st and 2nd gen models work with 3rd gen?

Any help would be greatly appreciated.

Cheers.

Hi Everyone,

Just for folks info:

Being a novice at doing mechanical work, but understanding the theory and with tips from the mechanics at work, I gave removing the fifth gear repair, described for the 4.1 and 4.2 gen models, a go, as it was a cheaper option than going straight to the shop.

I had the gear, sleeve and synchro case to replace. However, on the removal of the casing I discover a bit of synchro spring where it shouldn't be, so that could be my problem. I am awaiting delivery of that part to, fingers crossed, fix the issue. If not a trip to the shop and bye bye dollars awaits.

Well, good news folks. I received the additional parts last week and put it all back together. And after doing about 1200 miles over the last week, fifth gear is running just fine. Problem fixed in same way as 4.1 and 4.2 models, but the culprit was likely a less than $5 spring, rather than 5th gear and the collar.

 

I believe the synchro spring was likely the only problem, but I essentially replaced all the synchro parts, the case, 5th gear, and the sleeve to hopefully ensure another 10 years of happy motoring!

 

Cheers,

 

Dan
