How-To: 6-Speed Manual Transmission Oil Change

Last time I did mine, I made a pretty good mess, even using a pump that I bought with my MT-90. I wonder if you could drain, then take off the console and shifter boot and fill with a funnel and some poly tubing? Mine is due soon, I'll see if it can be done.

 

This should be a sticky up top with the 2nd gen how to's

 

if i am changing my tranny oil and have a tranny cooler do i need mroe than 1.9 qts?

 

Do you have an auto with cooler?

 

Pretty damn easy. I done mine almost like oil changes.

 

you have cooler for the MT. Do you have picture of this ?

 

You're right its pretty easy. I've used a bunch of different methods / pumps to get the gear oil in before. The one I just used was by far the best I've tried. If you're looking for a

pump try this one. I use some clear hose I had from a previous project and that also helped keep the spills down.

Kinda pricey but well worth it.

 

I just did this today for the first time at 30,000 miles. I put in the Redline MT-90. I'm kind of baffled by all the people on here saying it improved their shifting so much. Mine feels exactly the same. I still randomly get light "grinds" going into the lower gears. I've driven this thing like a granny and most of my miles are on the highway.

The old oil looked brownish and the magnet was full of sludge, so it's probably good that I did it.

I HIGHLY recommend this oil suction gun. It worked flawlessly and the tube is the perfect diameter. It sucks up about half a quart per "gulp".

"improved their shifting" - it's the placebo effect but it's really maintenance - it's not to improve but to keep it working thus maintenance. I bought a gun that looked like that one but didn't work and someone bought one at work so I tried that - it sucked oil up but then the oil just ran out. Is there a technique involved like holding it in a certain position or something ? Thanks for any reply.

 

You're probably right about the placebo effect, lol.

I just held the end of the hose upright so none would dribble out.

 

I did mine this morning. I currently have 6,800 miles and after driving it for just a few miles definitely feel a difference. 3rd is much easier to engage. FWIW, if you don't have metric sockets that go up to the size of the plugs, a 15/16" six pointed socket fits just fine.

 

Thanks for the reply. I'm a little older and I find it helpful to hold the end of the hose upright so none will dribble out

 

would someone please help me i got a 89 toyota pickup i put new wires plugs, rotor button but i can; get it to fire what do i need to do.....bcrufus

 

Haha! Someone else might have experience with a good pump, but I thought that gun was great for the price.

 

What is the reasoning for this?

 

I just changed out my tranny oil again (only ~8000km old, Penzoil or GM syncromesh oil I think) because it felt inexistent when shifting gears. Basically felt like straight metal on metal! I ended up putting in Royal Purple Syncromax because it was on sale for the same price as Redline MT ($15/quart, reg $45/quart). So far after driving around for a day, I can confirm that it's smooth and not grinding in any gears. Paired up with the TRD short-shifter kit I just put in and it feels pretty damn good.

PRO TIP: I tried filling my tranny without a pump by attaching some clear tubing to the nozzle of the bottle and running the line as horizontal as possible into the transmission. HORRIBLE IDEA! Made a huge mess of both me and my driveway. I picked up a cheap hand pump for less than $10, poured the oil into a container, stuck one end of the pump in it and the other end in the transmission and was done in no time.

TLDR; Don't attempt this without a pump.

 

Thread revival, whats the break in period for the 6 speeds? I really want to change to Mt-90, but want everything broken in first...i was thinking at least the first 5k miles before i start changing fluids

I honestly don't know if there is a break in period for the first fluid change but I changed mine at about 5-6000 miles. The Core shifter lets you hear gear noise that the stock shifter didn't. After the MT-90 most of the gear noise was gone. I still get gear "whine" but no rough sounds like when the stock fluid was in there.
