you need three quarts, two and a half go in.

 

Do I have to jack the entire car up or can I just drive the front wheels on ramps!!! Thanks, doing in the morning finally!

 

when the OP says:
"While you are under the car, go ahead and remove the "fill" plug circled in red in the picture from above. We will be filling the fluid from the top of the car but by having the fill plug out, we can guarantee we wont be overfilling the trans. When fluid starts coming out of the fill plug, you know you are good to go."

how do i approach that? do i place a bucket under the fill plug? will the excess trans oil come pouring out or drip slowly? so does that mean by the time i pour in the 3rd bottle of trans fluid in, i should be periodically looking under the car to see if fluid is coming out?

 

yes.

 

Couldn't you just use a funnel and put a snug rubber hose on the end of the funnel and snake it into the fill plug (without bends of course) ?

I am doing my tomorrow. I hope i don't over tighten the drain plug like the other guys. I have a tendency to do that lol

 

probably one of the more useful threads ive found on here

 

Ok i am about to do this oil change for my car and when looking for redline oil i went to their site and this is what the site says:

"This product is not designed for use in most manual transmissions or tranaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems"

Anyone have any problems like this?

 

i used royal purple 75w90 im at 3k miles since i changed it and oooooh boy i love it. no problems and shifts a lot smoother and easier, engages a lot more positively and really lets the motor run a little more toward its true potential.

 

one more update...

I used royal purple on my 5speed for between 15-20k miles and it let me down after I rebuilt my engine. I never noticed any problems with it till my engine build (i also replaced the clutch while i built the engine btw). so i went through the list of possible causes. I tried adjusting the clutch pedal, tried changing my shifting habits, made sure i had the proper amount of gear lube, i even went as far as throwing on a short shifter but to no avail. 2nd to 3rd would grind if I shifted too quick or 3rd to 4th. So i recently swapped over to motul 75w90 so far has been with success. no grind at all after 200 miles. Im not going to pretend to know exactly why but so far its worked. Ill wait for 20k miles though before i give a thumbs up..lol

I have a few ideas on why but again its just ideas.

 

im at about 12k on my royal purple and still no problems... its not perfect still but thats just the tranny... its not exactly built for craziness lol

 

Hey guys, I bought a used 05 scion tc with 139k miles. Car drives like a dream btw! :D

The tranny oil I believe has never been changed. Would it be safe to change it now at such high milage?

 

Yeah, the manual says 2.6 quarts of GL-4 or GL-5 oil type with the SAE viscosity of 75W-90. I just changed my fluids yesterday. I used Royal Purple 75W-90 synthetic and it made a significant difference!!! I'm very impressed. The engine's powerband is transferred to the wheels, the gears shift smoothly, the vehicle coasts soooo much smoother with ease, and the acceleration is linear. I'm sure my miles per gallon will increase too if I can refrain from being so heavy footed....Its the best 34 bucks I ever spent on oil....

On that note, the transaxle case ONLY took about 2.5 qts of oil before it began to leak out of the fill hole. This was a clear indicator it was full. I guess if one were to add fluids from the reverse sensor plug, you probably could get 3 qts into the transaxle case. which reminds me, how in the world did you remove the reverse sensor? Does anyone have any info on this? It would have made the job a whole lot easier....

 

This is the best pic of the sensor i could get at the moment (its a little dark out right now). Unplug the sensor, pictured in the middle here, and also unbolt the bracket directly behind it and pull the wire out of the way. Grab a deepwell 6 point socket to fit the sensor, sorry i dont recall the size i did mine a while ago, and CAREFULLY remove it. The resulting hole is where you would fill your tranny from. I was told by dealerships and other tuners alike to leave it in neutral and roll it back and forth a few feet while filling to let the fluid really get everywhere it needs to go. When the fluid starts to come out the "fill" plug on the side of the transmission you have enough in there. Let it get to a real slow drip out the side before you put the plug back in as it is possible to over fill and it will cause problems. After you are all filled up torque the sensor back down to 30 ft./lb.. Reinstall the bracket that was pushed out of the way, plug the sensor back in and you are ready to roll. *NOTE* When you are draining the old fluid out leave the reverse sensor in so the fluid comes out in a little more controllable manner.

 

if u still need help with it hit me up and ill do my best MRflint.

 

technically its not a flush, a trans flush is using a machine to cycle the fluid threw the transmission and the trans line but since a manual doesnt cycles the fluid the same way its not being flushed, more like a drain and fill
