1993-1997 A/T Drain Plug

[blumonster]

What is the size of the drain plug? Which tool should I use?

Do I have to replace the crush washer? I read that if it is metal it can be re-used.

What is the size of this crush washer? Is it the same size with oil pan's drain plug washer? If so I can find it easier at auto parts stores.

They do not even list the transmission drain plug washer.

I dont know the size but 17 or 19mm is typical. Use a good fitting socket or wrench of course.

Replacing the crush washer is best. Usually when they are used over they seep. A lot of time people are careless and let dirt get under it and that affects the sealing.

Only a copper washer can be reused but ONLY if its annealed. (Heat red hot and quench)

They are sized by the thread size of the bolt. Even if the parts store doesnt have a listing they should be able to set you up with a washer. It may or may not be the same size as the oil drain plug.

Some automatics DONT have drain plugs so dont be suprised if you cant find it. I cant say for sure on the Toyota since I havent had to work on any automatics.

Do a good job and pay careful attention to conditions for the fluid level, and that you get it right. Re-check a few times HOT after the job is done.

Thank you speedy25 for your explanation. I think I will go to the dealer parts dept. to get a new crush washer to be safe.

I have metric L shaped metric allen wrench set, I will get a hex socket set also in case L shaped allen does not work.

I am thinking of doing the first (and maybe second) drain/refill with Valvoline Maxlife Dex-Merc and then do another drain and refill with Redline D4. Do you think mixing these two fluids is OK?

Allen wrench??? Drain plugs I have dealt with have ALL been hex head. Sometimes the filler bolt might have an allen head.

^ Allen's are hex.

It's pretty large forgot off hand. But your standard Allen set generally doesn't go that big. You can just go to a auto parts store and try out a couple for free in the lot.

The drain plug can be reached by laying in front of the bumper.

No need for a new washer, Ive done a total of 6 flushes on mine. The original washer holds tight.


Instead of getting an Allen key just get a male hex socket for one of your ratchet wrenches. That plug is tough to break loose without a cheater bar.

Thanks for the reply gomes512.
The biggest I have is 10mm. I also ordered the hex sockets in case I might need them for other jobs in the future. 8.50 for a set from amazon.

Was the washer on yours metal or fiber?

[blumonster]

I do not have a hydraulic lift. I tried to reach the drain plug laying by the bumper, I was not able to see the plug. The front of the car was lower than the back because it is parked at 25 degree inclination. I will try parking the car to bring the front of the car at the higher elevation. That might help reaching the plug. Would that affect the fluid level on the dipstick and the pan?

[gomes512]

Yes keeping it on an incline will affect the fluid level. Always check it on level ground. I usually do it at the bottom of my driveway.

The washer on there is metal.

It may not be visible because it is ever so slightly recessed in regards to the skid plate on the pan. You can use a small mirror to get a look at it. Once you know where it is you can then get access to it by laying down.

If you still have problems seeing just bust out your spare tire jack and slightly jack up the drivers side (keep the wheels on the ground). That'll lift the body enough to get you more room.

Also if you have the 1.6 motor. The differential drain plug uses the same hex size. The fill, however, is 17mm socket.

It is 1.8lt version.
I just checked the plug.It does not have a hole where I can put the Hex sockets in. I think it needs a female hex socket if there is anything like that at all. The bolt has got 6 sides, I counted. The center is not recessed.Just slightly lower.
Thank you for your help.

This is the pan and the bolt.It looks like a hex bolt with a washer/flange. I am surprised it did not have an opening where I could use the hex key.
So I should use a regular socket? (Its size is similar to the size of oil pan drain plug size, I think.)

I just took these photos. After reviewing them on the computer I saw a moist area next to the transmission pan. Below is that photo. What do you think it is?
Is it normal?

[blumonster]

It is 14mm bolt.
No need for a hex key.

I just did a drain and refill with 1qt of Redline D4 and 2 qts of Valvoline Maxlife ATF.
