Actually, getting a flush is highly debated. Some swear by flushing, some swear that a flush killed their tranny. One thing that I have heard, and that I tend to believe, is that it'* okay to flush if you do it reasonably often. But if you wait too long, and you get built up deposits, then a flush can break them loose, and lodge them in all the wrong places, and it'* all downhill from there.

Your call, obviously. If it were mine though, I'd dump and fill. Not a complete fluid change, but you can do it yourself, and no danger of forcing bad things into bad places.

Yeah, I don't flush either as I've heard of it dislodging too many nasty particles. I just dump and refill as well... I figure dumping it gets most of the old crap out anyway.

Here are the videos.


This video is of a hot engine start. The car hasn't been sitting very long since it was last started (comparable to going into a store and shopping for a while).






This video is of my car after sitting overnight. It cranks for about 5 seconds. I stop cranking it and then try again and it fires right up. Sorry about the poor sound level. My cell phone doesn't record sound very loud.





Today I'll probably clean the throttle body and MAF sensor.

Okay, I cleaned both cable endings. There was a little bit of corrosion on the positive end but it wasn't too bad. The battery is fairly new (i think it was put in a few years ago). I'm going to wait for the engine to cool down a little more and then I'll clean the throttle body and MAF.

edit: I followed the directions for cleaning the throttle body as given by http://www.lesabret.com/phpBB/viewtopic.php?t=4054

and now I'm waiting for it to be ready.

guys, this car is extremely low mileage, it can withstand a flush. don't start this flush screwing up transmissions crap. that MAY be true in a high mileage trans, but thats only if failure was imminent anyways. for a transmission of this mileage, a flush and filter change should bring it back to like new condition.

if you choose to follow the advice of these pussyfoots Razz , do be sure to change it TWICE, otherwise you'll only get about 3/8s of the fluid in the trans.

I did a flush on my semi high mileage trans and it worked better than ever. don't be worried. flushing is recommended in the FSM and every other manual i've ever read.

Alright, I'll pick up some transmission fluid and filter. Hopefully this isn't too hard of a job and it doesn't have much of a chance of messing it up.

I'll have to keep an eye on that. I read the section of my repair manual about changing the FPR out and it seems very simple.

Also, could anyone tell me where the fuel pump relay is so I know how to relieve the fuel system pressure?

I'm gonna go off topic here...

I'm one thats a stickler for changing fluids... I can't stand to see the trans with fluid anything other than a reddish color...

Now on the flushes... Flushes are 99.99% of the time never going to be the cause of a failure... But it can clean the trans out to the point that some of the varnish in the trans was helping the seals and the like inside the trans... When the varnish or sludge is cleaned out it can cause the trans to fail, But at the same token the Trans would have failed along the line..

After having seen the 4T60-E apart, and the 60-E is very close to the 440-T4( 4T60 ).... There are filters in a couple of passages in the channel plate... If any particles break free and plug up these filters in the channel plate you will have problems...

At 60k I'd say flush it and then keep the fluid changed.... But flush it only if your fluid isn't Black or very dark brown, <----- If you have gotten it that dark, you may want to leave it along..

Now if the fluid looks decent and is a reddish or pinkish color with a hint of Brown, the flush may do you some good, as you'll get all of the old fluid out and replace with fresh fluid.. These old transmissions required more care and fluid changed than say a 4T60-E or 4T65-E... The THM440-T4( 4T60 ) would overheat the fluid in a bad way...

So hows the Fluid look?

Back on topic... This is a thread about starting issues
