Wow, did not know this. Sounds like a great tip!

reverse gear does not have a synchro. This is pretty common on cheaper cars.

I changed the gear lube in my 07 sedan at 100k with mt90. The original fluid looked as good as new...

Id go for the Redline MT 90.

Will do this soon, does anyone have the pics saved ( or is it just my computer that they don't show).

Second question is where to get Redline?

i'm on Royal Purple now, and my gears still grind somehow, reverse still stuck on cold morning, first gear still stiff, maybe Redline next time and compare.

inside the engine bay on ur tranny check ur linkages and grease/oil where felt needed. my 5th and reverse were stiff and toyota did this for me now all gears go with with ease

Just wanted to say thanks OP for posting this, I am doing a ton of 60k maintenance on my car, new plugs, new brake pads, and now thanks to you i have new tranny oil :-) much obliged!

Another thanks to the OP for this very helpful thread. I just passed 100,000 miles on my '07 and even though the dealer said that the transmission oil didn't need to be changed, I went ahead and bought some MT-90 from amazon.com and changed it today in addition to the coolant. Many thanks for this forum.

ROYAL PURPLE likely to be a GL-5 which is the same as the factory fill which causes the grinding and clunking into reverse . You'd want a GL-4 , like that of REDLINE MT-90 . Does make a big difference . Better shifting on cold days with MT-90 . Changing the gear oil is easier than a oil change . After the fill of the GL-4 , work through all the gears ( reverse too ) and before you know it shifting is a breeze .

I called around, found a place local that will sell the redline MT-90 for $9.95 per qt. Going to do this this weekend. I've noticed since I got the car that reverse is pretty chunky if not a little grindy at times. Will try this. No problems with any of the other gears.

Going to have to buy a few things first. I've never seen a funnel like pictured in the DIY. I'm going to have to get something similar to put it in that side plug. I also don't have a torque wrench. A friend of mine that I work with who also works on motorcycles says 29 ft-lbs of torque is not very much. Just a slight muscle flex as your tightening it after its all the way on. (course he's a pretty big guy so that's relative) Should I buy a torque wrench just for this? Is the torque that important? I also will need to get some kind of pan to drain it into. Do i just take the used oil to wal mart or somewhere? It's probably a good idea to buy something to transport the old oil in rather than in the open pan in the back seat, heh. Goodness, this is adding up.

Do this if you don't have a torque wrench . Take a medium to fine SHARPIE permanent magic marker with black ink and draw a line on the drain fill plugs and the tranny itself so they line up . Then write D.P. ( drain plug ) or F.P. ( filler plug ) on the plug so when you put them back in you'll be using the same plug so they will line up . Can tighten it just a bit more beyond the mark on the tranny , if needed .

Hmm interesting thing to do. But would it work if you changed the sealing washer? (also unecessary)

Torque wrench complete overkill for something like this however. Manual says something like "Torque the oil filter with a torque wrench. If you dont have one take it to your dealer for proper torque."

Just intimidating the public Im afraid. The bastards. Actually torqueing the OF to their spec will prolly result in it being nearly impossible to remove IME.

This method worked for the '08 YARIS 3 door w/ 5 speed manual . The permanent marker remained for a while . If I remember correctly , reused the washer from the factory . Would get a new one when doing a second change of gear oil .

i didn't notice this thread until I already did the job, and apparently I over-torqued the nuts. i was assuming they were crush washers like on my honda. is this a problem?

also, my oil was very dirty at 26k.

Went out to take the pic for my avatar just now and drove to a different parking place in the sun. I went from driving around in first to putting it into reverse to back into the parking place. Slight grind in the gear as I placed it into reverse. *shrug* hopefully the gear oil change will help.

Great thread and thx for the great pic's

I just changed my trans fluid today at 55,400 miles, Tranny fluid looked as good as new when coming out. No metal flake look to it. Installed 75w-90 Royal Purple and went for a drive. Well don't waste your 30 bucks on this oil. My car did shift better. On cold days before it would be stiff or hard to get into gear down shifting to second and to first. It is better, but not as good as I was hoping. In 5,000 miles when I change my oil I will be going to MT-90 and will update you guys on how that performs.

[Hershey]

Big difference , when cold shifting and no clunking into reverse . After the change , take it out for a spin and work through all the gears , including reverse . Not long after you'll be in for a smooth transition .
