Seattle Cl-S

I just finished installing the Comptech tranny cooler using a combination of their instructions and the DIY post by SilverBullet ( http://home.satx.rr.com/silverbullet/tranny.htm ). I decided I would need this for the supercharger install next weekend.

Now, my immediate question is which dot do I check to make sure I have enough fluid in the tranny? SilverBullet's instructions say to use the closest dot to the yellow handle. Now, there are 2 dots at the far end of the dipstick and a third dot waaaaay up the handle. Am I supposed to fill to the uppermost dot of the two near the tip or the third dot waaaaay up the dipstick.

Any help is much appreciated since I really don't want to drive the car until I know the tranny has enough fluid.

Thanks!

Fluid level should be between the two dots at the lower end of the stick ( far end from the yellow handle). Check fluid with engine off and on level ground. Should be closer to the top dot if tranny is hot and closer to the bottom dot if tranny is cold.

You'll enjoy the shifting difference with the tranny cooler. Much more consistent.

Thanks! I think I'm actually over the top dot right now. Guess I'll have to drain a bit out.

Where is the drain bolt located?

Better have a shop do this for you

Which brand tranny fluid are you using?

Seattle Cl-S

There is no "drain bolt". Maybe you're thinking of the fill bolt? If you look about 12" behind the battery and about 6" to the left, you will see a 11/16" bolt with "ATF" on it. You will need a breaker bar or torque wrench to get that puppy loose.

If you want to drain the tranny you either need a fancy pump or just hook up a fluid hose to the 'hot out' line and run it into a bucket. One word of caution: When following SilverBullet's instructions, I didn't understand just how fast tranny fluid goes through the system. 2 quarts comes out in about 8-10 seconds...really! Sure made a mess of my garage floor.

Comptech suggested the use of Redline ATF, so that's what I bought. CarQuest here in Bellevue carried it for $8/qt.

One day of driving and no spills yet. I sprayed down the engine so I could see fluid leaks a bit easier.

Can't really tell any differences w/ the limited amount of driving I've done so far. Some people claim smoother shifts but I can't tell a thing...just a little peace-of-mind when the SC goes in...

Once you have the easy-to-get-to transmission lines (hoses), it shouldn't be a problem to find a good tranny joint with a nice ATF flush/change machine to swap out the old fluid and they will make sure it all gets changed out and is perfectly clean. (And, no, I’m not talking about running solvents through the system.)

It would also be possible to leave in/put in some new/clean Honda ATF (in addition to the Redline or Amsoil) just to make sure that any critical additives are still "around" -- just in case there are one or more additives in the Honda product that prove critical.

You can only drain about 3 qts. of fluid with it.

Ah, I stand corrected.

So who makes the tranny cooler for Comptech? B&M? Thinking about getting one, not paying Comptech prices.

Eggplant-EX

Congrats on the cooler. But what I do not get is that we are all blowing trannies and you guys are adding the superchargers...

what am I missing here?

EricL

B&M

You can make some brackets or use tie wraps.

blader

yes B&M makes the cooler for comptech, I believe I saw an exact part number for a B&M unit that was the same as the comptech one in a thread once try a search .. the cooler is the same size and everything you just have to size your own fluid lines.

Some need for one or more of the following: the thrill of parachuting at low altitude, deep-sea diving with rusty tanks, high-speed chases in SUVs on Firestone tires, rattlesnake roundups, pit viper/cobra taming, and other pursuits.

That about sums it up. I guess I'm just feeling lucky...and I just don't really care. If the tranny goes :'( and Acura won't pick up the tab :sqntfawk: I'll just have someone build me a stronger one.

That clears things up. I had a feeling that was the one. So if only 3 quarts come out, what is the best way to add the redline fluid? I am thinking buy 2 gallons and drain and fill twice. That will still leave some honda fluid in which I am not sure how that will effect the tranny. Will the two fluids mix ok?[

The 2 fluids will mix OK. Redline and AMS Oil ATF are just better fluids, have better additives. They meet Honda's specs.

How much do you drive?

I would do a 3 quart drain the next 2 oil changes.

Or do 3 quarts now, drive for a week, then another 3 quarts.

Draining the car level will get about 3 quarts out. On ramps, I think people get 2.75 or something.

I have a short/low profile drain pan. I jack the driver side up, loosen the drain plug, and lower the car. My pan fits under the car, and it drains level. The drain plug it can be tight, I use a pipe on my ratchet for more leverage. The plug is 3/8. I use a 1/2 inch ratchet with a 3/8 adapater. The adapater gives enough extension to clear the trannycase. Torque the plug and fill bolt to the proper specs (I'd give the numbers, don't have my Helms right now). Buy a crush washer for the drain plug (#14). You can get it at a Honda dealer.

Hope that was not too much info

I learn so much on this site.

Bluto

I might have this backwards, 1/2 inch plug. Haven't changed the fluid recently.

EricL

I did a bunch of reading at some of the other Honda forums, and we are not the only folks who had slushbox problems. A number of people who were adding ATF, were keeping a bit of Honda ATF in the "mix" to insure that the additive package wasn't compromised. They were using a variety of synthetics. Maybe the Redline and Amsoil additives are AOK and fully duplicate ALL of the properties in the Honda additive package. However, when I've talked to various folks about this, they get kind of "funny" when pressed too hard.

I'd be dead sure about this if someone said, "We now have Honda/Acura approved ATF."

-- this is my opinion --

Bluto

AMS doesn't say 'approved' but 'Recommended for' Honda; Z-1. They recently added Honda to the list.

People use Red Line because Comptech pushes it with the SC.

I don't think Honda/Acura will ever approve another brand of ATF fluid, when they can force theirs upon us for $4 to $8 a quart.

I'm going to send a fluid sample to Blackstone from my new tranny when I change it.

I'm sticking with Honda Z1. Acura is generous with transmission replacements now, but in 3-4 years

EricL

Hard to know what Acura will do. With the emphasis on performance and factory mod packages, I'd hope they would be a bit less parochial.

And, here is a Mobil page (synthetic ATF):

"Builder approval" sure makes for a no-brainer.
