Anyone EOC with automatic?
 

Got to thinking about it I really do think I am going to try this mod when I get around to it even though I have an automatic I really think it can handle it. 92 nissan sentra GA16de, not sure of the tranny model but is 4 speed automatic. Tranny has about 250k on it now and fluid is squeaky clean between changes, no shifting problems. So I think I may try it unless someone who is really familiar with these transmissions say for sure that it will kill it.

I would start by seeing what your owners manual says about flat towing

Manual says for automatic transmission:

Observe the following restricted towing speeds and distances

-Speeds below 30 mph

-Distance less than 40 miles

...so don't kill it until you're down to 30, and if 40miles is a limitation, I think everyone will want to hear about it.

Yeah I think I am going to push it coasting will be done at a max of 45, thats a 15 mph difference and I am using more advanced fluids than was available in 1992, I mean if it comes down to it I may install a small electric pump to circulate the fluid if that is what it needs.

Total commute is 22 miles and only will be coasting a few spaced out points less than .5 mile each.

Well tomorrow I will start testing, looking at the inventory of the local pick and pull there is a dozen donor cars with manual or auto trans only $75, nothing risked nothing gained.

Why not look into a small electric pump like you said? It shouldn't be very hard to install it.

Yeah I will if I see any hints/signs of issues. But thinking about it, will be coasting for just a moment after fluid was just pumping just slightly above recommended using far superior fluids to stock, I really think it will be fine.

My manual says tow engine off 35mph and less than 50 miles, which I read later at the suggestions on this site.

Very shortly, 2 or 3 days, after starting mild EOC 45mph to stop and a few 60mph to 45mph coasts on the highway my tranny light coded, flashing OD off light. 2 weeks later and my car is at the tranny shop getting an overhaul. 145,000 miles with no problems. The indication is that the torque converter is not locking up now. May be coincidental, but really not worth it. My 2 cents, if you are running an automatic and want to coast do engine ON coasting in neutral twards a stop sign, traffic light or landing to park.
You have been blessed to get 250k out of the tranny, be good to it unless you are ready for an overhaul anyhow.

Points taken there something to consider for sure.

As far as the mileage I have abused transmissions with 380k, 573k, and 415k which was a mercedes(used as an undercover police car with mucha crazy driving once even ended up standing vertical!) Dodge d150 and a Dodge cargo van. So the mileage part doesn't scare me a bit but the part where it damaged in short order that part I am familiar with, once forgot to hook up a tv cable on a 700r4 in a car with 450hp.....gone in a few minutes....

I did do EOCing with a 2000 Caravan 3-Litre, though that was above the speed the manual stated.

I was about to say this I did the same thing in my 99 and my 01. No problems ever.

Ok I started slow yesterday, just did alot of EOC to park and to the mailbox. Didn't do EOC on any hills yet. No noticeable feel to transmission. Checked my fluid yesterday before started and will check it today with white paper again to see if I see anything.

I do it in my 08 chevy work van too and my Gfs 09 jetta and I used to do it in a dodge neon a ford explorer and a 96 contour. no problems ever.

Ok tried it on a particular hill but did not seem to coast as far as usual, will test some more this week to see if this is the case. If it is the case would seem to indicate that would be better not to do this...

Ok did some more testing and it coasted just fine, I might have coasted sooner yesterday than I usually do. Tonight I made sure to coast at the usual starting spot.

My odyssey has a similar 35 mph / 50 miles restriction. Since I'm only coasting for distances well below 50 miles, I feel I can push the speed a bit higher. That said, the benefits to eoc diminish at higher speeds. Neutral coasting gets more and more efficient at higher speeds, because you have a fixed idle fuel consumption divided over an increasing distance covered. I don't bother at highway speeds.

* in the Ody. My manual Fit spends more time in EOC than it does running.
