I think it's not wise to do so.

Something about the fluid overheating because it's not getting pumped around properly.

Also, I'm sure that putting it back into gear at speed isn't real nice on the internals.

But mostly the overheating fluid bit.

ya i was thinking it might be bad

v606er · April 22nd, 2008, 07:52 PM

yeah dude it burns up your tranny fluid, (supposely) but I know someone who has had there car for 100k and done that (put in netrual and costed with a auto) and he changed the fluid at 50k and its still good

Manualy downshifting the newer electronic overdrive tranny's spells disaster. Mine went with only 60k on the ticker. I manualy shifted mine often and one day it grenaded.

You've been here 1 1/2 years, have 600 posts and think your a forum whore?lol

TheBusher · April 22nd, 2008, 09:37 PM

I would say it's bad, and it MIGHT get you 3-5 more miles per tank depending on how often you do it...

2006GTARPD3 · April 22nd, 2008, 10:08 PM

Honestly You have a 6er and its not worth the damage. Suck it up and buy some gas, your not guzzling it as bad as the 8 bangers.

Unless the hill is around 1 mile long(seriously, my dad used to coast his VW GTI down one all the time, turned the car off once too just for laughs) why bother? Shifting into drive if you're still moving sounds pretty bad too.

v606er · April 22nd, 2008, 11:08 PM

well im definatly not doing that again

Trick Tuners · April 23rd, 2008, 11:13 AM

One thing to think about is that the car will go into coasting fuel shutoff during decel with moderate load. This uses 0 gas (less than idle). If you put it in neutral it will go to idle mode.

you're missing what he's saying...He's telling you it's saving gas by keeping it in drive...

Right. Coasting fuel shutoff turns the fueling off. If you have a wideband it will peg at 20. Take it out of gear and the gas turns back on and should run at 14.7.
