Here we go again... EOC & automatics

[Oval_Overload]

Eh...
Bad news...
I went to Stillwater Ford yesterday. It doesn't exist.
I was there a week and a half ago to look at a ZX2 for sale. Now, the place is deserted. Apparently the parent company is on the verge of bankruptcy because its assets are tied up in Chrysler Financial.

SO, at this point, no definite answer on the EOC in 'drive' thing.

I'm pretty sure I'm going to drive my wife's car without her being in it with me, and find out what happens.

This, of course, won't answer the question definitively, since the only definite answer I get will be "does it work on a '94 Grand Prix SE w/ 3.1 MFI"

I'm sure someone will have an opinion differing from what happens if I get a positive result.

Neutral coast engine off automatic. IM IN UR FORUM MESSING WIT UR ACRONIMS

Hi all, Interesting discussion.

How long does it take for the bearings in an auto to go dry after the pump stops. I would imagine a helluva long time. The reason oil starvation in an engine can be quick and catastrophic is mainly the cylinder walls. They can go dry and cease pretty fast due to the heat and the rings scraping oil off every stroke. Then the piston stops and your crank keeps going. An automatic does not have these harsh conditions so the seconds that elapse during a reasonable coast could not possibly starve the bearings enough to do any damage... In my opinion. Also, in neutral there is very little pressure on anything, just rotation as far as I know.

If someone could explain how all that oil will magically evaporate then I might believe the anti coast theory.

Anyone?

Anyone actually experience a failure under these conditions?

I want to believe.

Hugs and cookies.

Most of the wear comes from needle bearings that aren't lubed as well as they could be from what I've heard, not as strong as ball bearings and not splash lubed means bad things could happen at any point in time. As long as it stays in N I don't think you'll see issues w/ the clutch packs.

Let me know what comes of that! I have a '93 Lumina Euro with the 3.1 MFI, and would love an answer!

Also note: I work in Bloomsburg - nice to see a (relatively) local!

I'll be sure to let you know what happens, as soon as I do it... unfortunately, that will require me coming up with an excuse to drive her car, which would also mean I have to stop being lazy and get up with her in the morning so I can take her to her rendezvous for her ride to school. (5 am is early.. wah.)

I can't think of where Bloomsburg is... and I wish I still had work LOL.

I'm up Route 11 from you, about 60 miles. If we want to go shopping and make a day of it, we'll go to Selinsgrove - that's closer to you, maybe you recognize that name.


I shut my car off in gear this morning. 35 MPH, was most likely in 3rd + TC lock (it was about 1500 RPM - don't know if it was 4th or 3rd + TC lock). Turned key back to run, and car kept coasting. Engine did not re-ignite; I had to shift to N and manually re-start.

was the engine still spinning while the car was off? You'll feel/know the difference immediately if the engine is still spinning, not to mention that when you turn the key back on (or in some cases, even while it's off) the tach will still show RPM immediately.

If you're in lockup mode, chances are, you're not going fast enough for it to work.

Since you have a tach, drive in 2 or L until you get up to about 2000 to 2500 RPM, then shut the key off and leave it in gear.

As soon as you turn the key off while you're in lockup mode, the TCM/ECM unlocks the torque convertor.. it's an electronic feature. Which means that you're way outside the realm of the engine starting back up when you turn the key back on.

No, it was definitely off - felt it cut out and tach dropped. I have to run out for lunch today from work, I'll possibly try it then.

Keep us posted.
