View Full Version : Changing Trans Oil....

Now I'm prob stating the obvious but here goes anyway. Here's an easy way to refill ur T50 after jacking up the front end, draining the used oil, etc...

Grab about a 1.5m of some small diameter clear PVC tubing from Bunnings or any other hardware store.

Crack the filler plug on the trans and get her opened up and ready (pray to the good Lord that the dude before you didn't use a freakin rattle gun to put the plug in as on mine)...http://www.ae86drivingclub.com.au/forums/emoticons/huh.gif

Get ur 4litre bottle of trans oil that ur going to use to refill the T50 and pop it on the cam cover of ur 4ag (if u have one) or somewhere upright and solid in the engine bay.

Open the bottle (suppose you see where this is going), drop in one end of the tubing and feed the other end down the side of the trans.

Jump under the car and start suckin'.... suck the end of the tube til you're about to get a Castrol facial and then let the siphon kick in (don't worry, you'll be able to see the oil coming down the tube well before you cop a mouthful...)

Stick the tube in the filler orifice and stand back....when the oil starts running out of the filler hole you know ur done.

The time it takes to fill depends on the diameter of ur tubing. I usually get a texta and mark the oil bottle on the back where the clear level is before I start. This way you can sort of see where ur at with the filling. From memory I think it's about 1.4l on a T50 but don't take my word on that.

i've found its easier to fill up by removing the shifter

Hmmm that's a good call upgarage.... but you've still got to get under the car to undo the drain plug anyway etc. Don't you have to remove all the plastics etc from the center console (assuming you're still using them)?

How do you know when it's full....measure it out exactly using a jug or something?

You could undo the fill plug first but that kinda defeats the purpose...then you may as well just fill it from there.

Cheers for the POV...

i remove the drain plug.. remove the filler plug.. drain the oil.. put the drain plug back in.. (leaving the filler/check plug out) and fill through the shifter.. once it starts to leak out the filler/check plug, she is full http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif same as the diff.. http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif easy as 1...2...3...

but yeh, you could do it this way also http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif the full mark will be when oil starts to come back out of the filler plug.. http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif good work arjay

also a quick note.. T-50's LOVE RUNNING ON AUTO TRANS FLUID!! garuntee if your gear box is a bit notchy or crunchy, befor you pull it out for a rebuild.. drain the box oil (ha ha ha box oil.. groooosss..) and refil with some good old dextron III auto trans fluid http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

My bf just changed my gearbox oil yesterday. He used a old 1litre trans oil bottle with a 10cm hose conneted to the lid. He filled up the bottle then got under the car and squeesd the oil in. He had to refill the bottle and repeat the process a few times, but it didn't take long before the box was full. http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

If you're filling it up till it runs out the filler, is ther car supposed to be level when filling the box?

yeah, should be

Oil gun/syringe thingy works....sometimes. I had mine fail the other day, and leaked about half a litre all over me and the floor http://www.ae86drivingclub.com.au/forums/emoticons/dry.gif

yeh have the car sitting as level as you can.. the exact amount of oil in the gear box doesn't really matter as much as an engine.... as long as it's with in a few 00ml... http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

thinner, warms up quicker...great for 300,000km old t50 shitboxes http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif with no synchros left

home made dogbox's are cool

MC68 hit the nail on the head... thinner works better with fucked out gearboxes.. my gear box wouldn't shift at 7k + with castrol VMX 80 and some other various types.. with auto fluid i'm flat changing with no worries!

I'm using Castrol Syntrans 75W/85, it's a synthetic Gear Oil. I found it really improved the way the synchros feel and it shifts really well. unfortunately its' like $25/L. You can use Auto trans fluid, most people mix it 50% ATF - 50% Gear oil to help improve shifting. The problem with running 100% ATF in gearboxes designed for Gear oil is that it doesn't have all the friction modifiers in it to help stop synchro wear.

Aaaaahh, so this is why you only use ATF in gearboxes with fucked up destroyed synchros.

ahahahaha phsycofox u just gave me an idea http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

how about 85w140 hypiod diff oil mixed with some leftover dextron 3 ive got

so that would be a thick diff oil, mixed with a thin auto fluid... you might as well just use a thin gear oil.. if you just use straight dex 3 will be beautiful..

Doesn't ATF have small particles in it to help the clutches in the auto boxes to engage?
I would have thought that if it did those particles would cut a rooted box to shredds in second.

Please correct me if I am wrong (probably am).

btw the guy who rebuilt my mates box in his BMW said he should run a thick engine oil like Penrite older engine. Is this a good thing to use or not?

sorry to hijack your thread
