5th gear popping out; taller replacement?

Hi all. I have an '02 5-speed, and it just started popping out of gear after 180,000 miles and an untold number of miles where the shifter would move while in 5th gear and under load.

I've found a number of posts that detail the DIY fix (the fabled original, this TOC summary, 4.2-specific with pics, another 4.2-specific summary). Thanks to everyone who contributed!

My question is whether there is a suitable replacement 5th gear that I can purchase for my belov'd Red Ravver that would supply it with a taller gear. In the stock setup, highway speeds make for a very noisy RAV, so I'd like to give it lower highway cruising RPMs while I am already swapping out the worn fifth gear for a new one.

Any suggestions? Can this even been done?

Thanks everyone!

I have nothing to contribute to this thread other than I have wondered this exact same thing. I look forward to any information we can get on this.

Alright, so I've confirmed that my RAV, a 2002 5-speed AWD, has the E352F transmission. This comes with a 5th-gear gear ratio of .820.

My question is whether a 5th gear and 5th driven gear from a 2002-2009 Camry, which has the E351 tranny, would fit in the E352F. If so, I am going to give it a shot, so does anyone have insight about the gear inner diameters and other relevant dimensions for these transmissions?

Thanks for the support. So far, I've posted in a Camry forum, and one person said I'd be the first to see if the gear fits... so I may be in uncharted waters, though I doubt that I'd be the first to discover the relationship between the transmissions.

So I'll ask again: Does anyone have any experience or knowledge?

Here's what I've found so far:

-At least some of the E-series transmissions from the 2002 era have interchangeable fifth gears due to their using the same gear spline and bearing sizes. As far as I can tell, this is the case for the E352f (2002 4WD 5-speed RAV) and the E351 (2002 Camry along with many other cars)
-At least 1 edition of the 2002 Camry uses the E351 transmission, which has a bigger fifth gear ratio (.732 for the Camry vs .820 for my RAV).

I'm ordering the parts I need tonight, so I should be ready to do the repair in 2 weeks time.

I'll keep you all posted. Wish me luck!

Felix - how do you tell which gearbox you have? Is it marked somewhere on the casing?

Good luck with the modifications.

This link has helped identify the different variants. Also, I have a repair manual for my 2002 RAV, and it tells me the only one for the 4WD version is the 352f.

At the same time, I have a hunch that it is stamped on the case.

Thanks Felix and also for the link.
So if I replace my 2003 E352F gearbox with a E359F, my car will be quieter in all gears except 1st and reverse?

Because the final drives are the same and the gear ratios are slightly lower in the E359F, if all else stays constant, the RPMs should be lower in the 359F.

I have no idea what you'd have to do to swap the tranny though; that's out of my wheelhouse!
