Directions anywhere? Easy? Any gotcha's?

I can't find the "old" DIY area with procedures and pics.

Thanks!
 
God, are you lazy!!! It's an almost new car. It can't need it already!!:biggrin:

Don't forget to get the big crush washer for the fill plug & 3 qrts of your favorite synthetic trans oil. I'm using the amsoil. I know there are 27 threads on old Honda MTF, the new Honda MTF, various synthetics, GM syncromesh + friction modifier, & the new Honda MTF. The drain plug uses the same crush washer as the engine oil drain plug. It helps if you have an assistant to either hold the funnel or hold the end of the hose in the fill hole. I did mine with the car on the ground, no jack or anything.
 
I just did mine today!

40 minutes at the most. difficult level of 2/10.

I used the Honda Manual Transmission fluid. I wouldn't use anything else.
My '91 has 31900 miles on it with no record of the fluid ever being changes.

Probably didn't need it as per the mileage. Oil doesn't go bad with age. Otherwise there would be an expiry date on th bottle.

Just piece of mind for myself.

What I did was put a level on my spoiler (use a towel to prevent scratches). Jack up the rear, and remove the rear wheel. No jackstand required. Just make sure you have a good jack. You can see both the fill and drain plug once the wheel is remove. Loosen the fill plug first, then the drain plug (just in case you are having trouble with loosening the fill plug, you still have MTF in your transmission. When draining your fluid, lower the car until it is leveled to drain as much of the fluid out as possible. Once the oil is drained completely, raise the car, tighten the drain plug, and lower the car until leveled. Insert the fill tube into the fill hole from the wheel well and fill until oil just comes over the fill hole thread. You will have excellent visibility to when the oil is coming out of the fill hole (just fill slowly). Then stop and wipe off excess oil by the thread. Should take no longer than 1 hour unless you are cleaning other things when you have the wheel off (I did). Hope my instruction helps.
 
Can you confirm both the 5 and 6 speeds take THREE qts? Dealer tried to tell me the 6 speed took 5.

There is NO SUCH THING as a "good" jack for this purpose. NEVER get under a car and trust your life to any hydraulic seal. ALWAYS USE A JACK STAND. Floor jacks do not have mechanical locks, there are not safe for getting under the car, EVER.

Larry,
I would never get under the car without a jack stand. The good part is I don't need to get under the car. I can loosen the drain plug with a 2X4 (resting on the ground against the rachet wrench) and a light tap with a 2 lb hammer to loosen the drain plug. After that eveything else is accessible from the wheel well without having to get under the car.
 
What if I accidently put more than 3 quarts? Won't hurt anything? It will just keep oozing out until the desired level has been maintained. Then cap it.

You can't, it will spill out.

Your comments were not clear on that, and people may take that as get under there without a jack stand. Glad you do not.

Another great thing about the NSX is the three jack points per side. Jack up the car using the middle point, and put stands under the front and rear points. It makes me wonder though, how it's done on cars with just the front and rear jack points. Where do the stands go?

The stands would go under the jack points, and typically you would raise the car using the suspension arms or a strong chassis member:).


HTH,

This schedule says every 24 months. Are people not doing it that soon?
I am.

Yup. Not only does this help with jack stands, but it's also handy when you just have to swap wheels and tires (like for track use); you only have to jack up the side of the car once to swap both wheels/tires on that side. I found another advantage recently, when I had a flat tire (blowout, actually). The flat had lowered that corner so much that I couldn't fit the jack under the jacking point next to that wheel, so I just used the middle one.
 
What is the LATEST consensus (did a search already) on the best tranny fluid. Don't know if it makes a difference but I have the Short gears/R&P. Use Redline and it's sometimes hard to get into gear. Larry B.?:biggrin:

Im planning the white cap Honda MTF for my stock vehicle. I would love to know what LarryB thinks.

Ken - what are you using?
 
I did this today. Other than almost cutting my thumb off (no glove pounding on a breaker bar) it was easy. Not too messy.

I took the drivers rear wheel off. Much easier that way.
 
I've recently used the Honda white cap stuff in mine and it made a world of difference - I'd definitely recommend.
