What are some options with types of transmission fluid you can put into the tC? You used Redline MT90, but are there others you can use, and if so which ones? I know very little about changing the transmission fluid, thanks for the answer(s).

 

Im sure there are other fluids like Amsoil and Royal Purple but I havent researched or used them so I cant say for sure. I just know the Redline has been used with excellent results in the past so I used it. I do know the Mobil 1 should not be used though as people report lots of grinding with it.

 

So you fill it up till it reaches the top?

 

No, you fill it up until fluid comes out of the front plug circled in red in the pictue which you would have removed while filling. That plug is designated as the "fill" plug even though we are not actually using it as such.

 

Sorry for the n00b question, but is the fluid going to keep coming out of the fill plug or will it stop when you are filling it up?

 

When the fluid starts to come out of the front fill plug you would stop adding fluid.

 

honestly, I have never bought trans fluid before. If I go to the store there is going to be bottles clearly marked Redline MT-90- correct? .....and im going to have to get 3 of them correct? Do they just come in one size?

 

Redline is more of a specailty item and may not be available locally (at least the gear oil). I got mine (3 bottles) here:

by any chance - do you know how much handling was?

 

Shipping/handling on my order was $9.75

 

Will this apply to an AUTO?.....sori noob here..

 

no...5 speed only

 

does the car come with automatic fluid (im sayin the people w/ manual). I thought I read somewhere that a lot of cars are comming with auto fluid.

 

Ours does not use ATF. It uses a GL-4 (I beleive) 75w90 gear oil. All of the fluid specs are in the manual.

 

... ?

ATF... automatic tranny fliud. for auto trannies.

 

ok - one more day and i forget to look at the specs. figured I would throw that out since you guys know what you are talking about.

 

does anybody has a DIY for an AUTO?

 

So we drain it completely before, we change to the new product. But is it possible to get all of the old stuff out? Wont there be a little left over that will be mixed with the new different material being added?

 

Im sure some of the original fluid will be left over but it wont cause any problems. The same is true when changing motor oil, brake fluid, coolant etc.

 

When Centerforce did my flywheel and clutch they used Royal Purple in mine. It seemed to make a difference like you said. Great write up by the way. When they did mine, we used the normal drain hole and used a pump that goes on the bottles and pumped the fluid into it. Worked good that way too, but you did a great job on the write up.
