During my install of some RR Racing USRS housing/bushings today I took the time to inspect the undercarriage as one should always do while under their car. All is good...no leaks and nothing out of place or broken. While inspecting the trans pan for any leaks I find myself looking at what looks to be TWO "drain" bolts for my AUTO trans. I know we have all said for many years these are sealed transmissions and all; but just to clarify, have we said that because there is no fill bolt holes or because others had no drain bolt holes? Here is what I found :



I'm just about to cross over to 100k miles and would like to remove some old fluid for some new. I currently DO NOT have any trans-related issues, otherwise I'd not be doing this. Some have stated that they've located a "fill bolt hole", but it must be difficult to spot because I couldn't see anything. But at least the drain part will be cake. LOL!

So bottom line, those will more recently built transmissions, do you even have drain bolt holes?

 

The 14mm nut is drain hole while the other nut (Alan key) is oil level check. The reason they said it sealed cause you cannot change all the fluid like other car. The most fluid you could change is only 1.7 quarts out of over 9 quarts total volume (if I remember correctly)

 

14 mm is drain bolt and fill bolt is top driver side. All you need is to drain and fill. It take about 1.7 quart. Drive around and keep drain and fill about 3 more time. Or brining to dealer for transmission flush. I

 

Is there any difference in the source of where the trans fluid comes from if draining from the "oil level check" bolt vs the drain bolt? Seems really weird to have two that seems to both source the same fluid from the trans fluid pan.

I also have to ask, why have an "oil level check" at all? What is its purpose?

Lastly, what have others used in the past to pump fresh trans fluid into the case? A quick search brought this up which is a cheap kit that will seem to work :

^Great FULL explanation of the entire process! Thanks man! I miss the ease of the trans fluid changes of my Civics.

 

you and me both, I actually just pulled and rebuilt the engine on the GSR and forgot how straight forward it is to work on an older car over the IS.

 

^Nice! I rebuilt my brother's LS trans for his B-day like 4 yrs ago and now it just sits unused in his garage.

He needs a new OBDII LS motor and just doesn't care about the '98 Teg anymore. I've rebuilt and BUILT too many SOHC 5sp trans to count. Had the most mint Si trans (sohc) in my boosted Civic with a Quaife LSD that the Honda factory had actually used in one of their factory race hatches. Even received their original purchase invoice!
