Hey All, I was wondering... My tranny seems a little harsh at times, but figured I was just paranoid. Anyway, this weekend I was running through some mountains in NH, and I let the car roll down the hills in neutral. When I went to put it in drive, the indicator on the dash said D, but the tranny would not engage. Took about 5 tries, and then it dropped into gear. What do you think? Not the first time I put a vehicle into N on a long downhill run, but the first that didn't want to go back into gear. Tried it later on a differrent hill, and it was fine. Guess you can call me Paranoid Pablo!

Yep, your paranoid. It won't work!

Fnky will probably jump in here, but I've tried this too and its normal for our cars IMO.

I only had it do this once... I got a little freaked out as well. Usually it engages.

Prolly not great idear to be putting in "N" and coasting anyway.
Kinda reminds me of the old days, take a rental, get up to 50 MPH and try to shove it in reverse!!

If I remember correct, these cars don't like being put in Neutral when driving at all! I think one guy actaully went into limp mode when he did that...

What's the bi deal with putting it in neutral? How can it hurt? Not trying to sound cocky, just curious. If it is just freely rolling, how can it hurt anything? I didn't try to slam it into 1st or 2nd at 60! That might be fun on someone else ride, or a rental, but not mine! My Superduty with the diesel just rolled away on the hills, as the diesel doesn't have the same engine braking as the gas engines, or something like that.

Why are you doing this? To save gas or something? Just wondering why you have a habit of coasting hills in neutral?

Hummm...I'm gonna pull out my owner's manual....I think I read something in there pertaining to this...




Page 208 Owners Manual for 2005 Dodge Magnum....

"Neutral
No power is transmitted from the engine to the drive axel. When the brakes are released, the vehicle can be moved freely (pushed or towed). Do not engage in neutral position while driving execpt to coast when the vehicle is in danger of skidding (e.g., on icy roads).

CAUTION!
Coasting the vehicle, or driving for any other reason with selector in neutral can result in transmission damage that is not
covered by the limited warranty."

As a rule of thumb, never drop an automatic transmission into neutral while "coasting". It is a *very* bad idea. They are not designed to do this.

I don't know why, I'm just pulling on the vast experience of others. I've had people like my father, gear head friends, and others tell me it is a bad idea to put an auto into neutral downhill.

I imagine it has something to do with one part of the tranny spinning incredibly fast as it is coasting (drive train) and the other side of the tranny spinning very slowly. Engaging the transmission at this point would send a very large jolt through the drive train. All that sudden torque could wreak havoc me thinks.

I have a slight understanding of transmissions and shifting. It seems like when you coast a manual you can go right into the proper gear. Perhaps the automatic isn't "smart enough" to automatically go into the highest gear so dropping it into drive may be hitting a low gear and quickly shifting to a high one...

just some thoughts.

I have had some clunking issues when accelerating at times. I have a feeling it is a universal joint

Don't have a habit of it. Just rolling with the terrain this time. Never heard it being an issue. It was actually more fun coasting through these decents on my bicycle, which I had just taken over the climbs. 45 MPH on 23mm wide tires! With turns. Ye Haw Cowboy!

I have had my tranny stick in second gear when driving it hard(most of the time!) & wondered if anyone else has had this happen. I have to go to neutral as it will stay in 2nd & not shift even as I go up & down through the gears??? I've only got 32000 km's(20k miles) & wonder whats next.

I don't know about you with your Hemi AWD, but on my SXT AWD, I usually accelerate when off the throttle coasting downhill in O/D.
