Transmission drain plug... - Toyota Nation Forum : Toyota Car and Truck Forums

Kingdom934 · 07-25-2008, 08:34 PM

I was thinking to start doing a drain/refill by draining the fluid in the tranny and refilling it with fresh fluid every other or so oil change since I could use a fluid change since you don't get 100% of the fluid out of it unless you do a flush. I could do a flush, but it'll run a bit more and require more tools.

Anyhow, I've seen that a '98 Corolla has a bolt that you can simply get a wrench or socket and it'll come off; however, when I went down to look at my '85 Camry transmission pan, I found it had this odd shape drain plug. Anybody knows what I need to take this off?

*Also, anybody knows of any online site where they sell Genuine Toyota parts? I just went to the dealer ship and they quoted me $51 bucks for a fuel filter for the Camry. Wondering where I can get it cheaper*

Allen wrench looks like to me. Same thing on the rear end/transaxle case also Just drained mine yesterday. Any big lots or sears or any place has them. I would do a darin and fill over a flush. People sometimes
say flushing old trannies causes them fail afterwards

10 mm 6 point Allen wrench

Thank you! Looks like I gotta go head out for that.

Also, do you folks know if you need to get a new crush gasket/washer for it like how the oil drain plug has one?

It has aluminum washer; I usually applying 1/8" bead of Ultra-blue rtv sealant on the top of this washer.
so it is going to seal the threads at the bottom.

I just did it today! took about 30 minutes. Its a 10mm hex key. runs you like 10 dollars ><! i picked up a 10 set of keys for 7.99 at walmart today

Kingdom934 · 07-26-2008, 10:17 PM

Alright.

Thanks you all for helping me out. Now to actually do it. I'm tired as of right now as I just did my friend's '95 Camry V6 oil + filter. The oil filter is a pain to get to when the car has been running XD...

Don't forget the torque converter. It uses the same fluid. Always open the fill port BEFORE opening the drain plug. Located on the back side of the transmission and uses the same 10mm allan wrench.

Correction to Kep's post:
It is not torque converter it is differential
for
aych: the drain plugt must be tightened to about 25 lbs X ft

Kingdom934 · 07-27-2008, 08:23 PM

Yea XD. I gotta do that one day.

LOL, I remembering people who drained their differential but when they tried to take off the fill port to fill it up...stuck.

But...I know the tranny fluid was changed before, but I don't the differential was ever changed. Worth doing it?

aych · 07-27-2008, 11:41 PM

oh. no torque wrench here. i just gave it a good tug

Doctor J · 07-28-2008, 08:59 AM

For differential , I would suggest to open the fill plug and check the level. If it filled with ATF, just add more if necessary, if some one filled it with gear oil [80w90 or similar], it can be either drained, flushed, and refilled with ATF or left alone, however the gear oil causes scoring of differential pinion thrust washer

I would want to do the differential, but I don't exactly have all the tools. I wonder when the differential was done...if was.

Anything worth noting about the differential and a fresh amount of fluid for it?

I want to do the drain and refill for the tranny, but the weather hasn't been great here as of late.

aych · 07-29-2008, 09:14 AM

a couple points.

the drain and refill vs the pump and refill are very similar. the amount of atf fluid removed is give or take +-0.1L. Im not sure about yours, but mine, after 300000km's the gears are so nicely worn, there is no grinds stuck to my magnet. my magnet was still shiny when I pulled it out. So if you dont have a hex key that size, pump is probably easier.

the differential.. im really not sure if that needs to be replaced. its been 20 years, 300k.. i haven't changed it once. the car is as smooth as anything.

Kingdom934 · 07-29-2008, 09:55 PM

I just did it. Boy, was the camry ATF like...dark brown. No sign of red. Also checked the fluid while pouring it out, doesn't look like there was any metal particles.

Since I was on a row, I did my cressida too. The Cressida '87 had a 14mm bolt. Did it too and it wasn't as bad as my camry, but pretty dark.

Another question, how much ATF do you put in? I filled it until it was halfway between the 'COLD' and 'HOT'.
