Hey,

My uncle and I are in the process of flushing the transmission fluid in my 1994 honda prelude SI with 17x,xxx miles. So far we've been taking 2 quarts(aprox.) out of the pan via the means of a fluid evacuator. Then after a while we'll repeat the process. I just did this for the 2nd time today and I can really tell that my car is shifting smoother. We're using OEM honda fluid.
Oh, by the way, my car has an automatic transmission. First car, you know. Anyways, my friend today told me that he thinks you should drain it out the bottom because on most cars the cap or plug on the bottom of the transmission is magnetic so it collects metal shavings and so on. He really thinks this is a good idea. It seemed to make sense, but I'm still learning about cars. I was hoping I could get your opinions. So far this seems to be working fine the way we are doing it.

 

Are you saying you used a pump to suck the fluid out of the dipstick shoot?
And wondering if you should be using the drain plug instead?
If that's the Question I would always use the drain plug. For a few reasons.
You can not get as much of the fluid out as you can pulling the plug. It's designed to be drained that way.
Also there could be a sludge layer at the bottom that you have been leaving in there. I don't know if there is a stock magnetic plug or not.
So I recommend draining via the drain plug.

 

Yep, you understood my question right. Thanks for the response.

 

yea always drain out the bottom. then run as many quarts as you want through to try and clean it out

 

Hey where is the car is this tranission dran and plug to pour new oil in? I think i need to flush mine too.

 

theres a 1/2" recess in a bolt on the transmission case just connect a a 1/2" drive ratchet and loosen it, let your tranny warm up first it will help sludge loosen up be sure to wipe off the drain plug before reinstalling it i think there all magnetic and some shavings/sludge will be built up on it
