is it good practice to shift to neutral, while driving downhill on automatic transmission? the owner manual does not recommend, would like to know why.it makes sense to save gas, while doing this. (i used to do it while driving manual)
View 7 RepliesI notice my instantaneous gas millage goes up if I coast in neutral in my new Volvo V50; say when cruising up to stop lights or coming down a hill. I appear to be saving gas, but am I damaging my automatic transmission?
View 8 RepliesSo yesterday after running an errand I got home, after having dinner I was about to head out and, SURPRISE! The car wouldn't start... The engine doesn't turn, no lights on the gauges when inserting the key, no clicks.... the battery seems fine, as the radio works, the anti-theft/alarm works well, the 2nd key behaves the same way.
This morning, I called VW road side, the tow truck they sent couldn't take the car because it is in a tight spot and we can shift the car to neutral. We tried resetting the ECU by disconnecting the battery without success... What to do??
1986 S10 blazer automatic transmission won't go into reverse OR neutral! It goes fwd in both reverse and neutral. It goes into park just fine. The fluid is full and not burnt. It will drive forward when in reverse and in neutral. I turned the engine off and checked neutral, it was not in gear but tried to go forward as soon as I started the engine.

View 11 RepliesI have a 1998 GMC Jimmy and until now we had little to no heat. In the morning when we first leave the house in the cold as we are speeding up we slip into neutral and we either have to pull over or shift the shifter into neutral and back to get it going again. We only notice this happening when it is very cold. How do we fix this before it becomes a bigger problem?
View 3 RepliesWhat normal idle rpm is with a/c on with automatic transmission. Mine fluctuates between 680 to 710 with condenser fan on low and 900 when high speed condenser fan is on.

View 1 RepliesI have the 4r100 transmission how do I bypass the safety switch? Also what are your thoughts on starting the engine with the transmission out? I know to bolt the spacer plate to the engine.
View 7 RepliesI have a '94 E4OD trans in my '53 F100. It uses an analog MLPS for the gear selection indicator, Neutral Safety Switch, and Backup light.
My MLPS Neutral Safety Switch shows continuity in Neutral, but not in Park, I need to be able to energize the starter solenoid in both Park & Neutral.
Shouldn't the MLPS show continuity in both Park & Neutral?
I was driving around some very steep hilly highways recently. I have tried this in both cruise control and normal coasting.
I noticed that the Tiguan will automatically downshift when going down a steep enough incline and a certain higher speed is automatically reached. Whether that is based on what was set by your cruise control, or even when letting the car coast down by releasing the gas peddle, it will still reach a point of downshifting automatically.
What I hate about it though is that this downshifting causes the engine to suddenly rev very high RPMs. Its also pretty loud at that point. That's bad for the transmission system right?
Usually in automatic mode driving, gear shifts up at around 2,500 RPM (mostly around 2000 RPM point). But when you are going downhill in a steep incline, the Tiguan automatically goes to a lower gear causing the RPM to shoot right up. I've had mine go up to 4,000 RPM downhill and the engine screams and spins really fast as you can clearly hear. It of course does the job of keeping the car at a certain speed, but is this bad for the transmission?
I mean, I prefer pressing on the breaks to control speed downhill. Break pads are cheap and easily replaceable. Transmission strain and failure is a whole other business. So I would prefer the strain be placed on my breaks and not my transmission system for the purposes of controlling speeds downhill. The latter failure mode will be the case if they rely on the transmission to control speed downhill.
So what is a "happy RPM" for the engine anyway? What RPM is the 2.0T engine at its most efficient?
I have a 2005 Camry, Base, 4cyl, 190k. The last couple of weeks while everyday driving the engine will rev up like the transmission has gone to neutral. It only does it for a couple of seconds and then back to normal. There is no rhyme or reason why it does it. We bought the car brand new and the fluid has never been changed.
View 14 RepliesMy wife's 2004 V6 Camry is not happy. As you accelerate from a stop, the automatic transmission will go from first gear to second, and then sometimes just drop spontaneously into neutral. Because you are in the process of accelerating, the engine RPMs increase until you take your foot of the pedal. In the short trip to the dealership for testing, the problem seemed to reset itself when the car was fully stopped. Other times it just reengaged with the transmission on its own without stopping.
Each time the transmission disengages, another strange thing happens--the instrument panel goes bonkers. The speedometer needle drops to zero, but the tach keeps working. The ABS, check engine, and brake lights turn on.
The dealership had the car for several days and has only been able to scan codes indicating the ABS system and the rear wheel speed sensors. I'm skeptical--especially since the repair estimate is nearly $4,000! I'm taking the car to an independent shop tomorrow for a second opinion.
I can follow up with more details from the dealership's diagnostic report, but for now, all I can say is that the car has almost 100,000 miles and we haven't had a bit of trouble with it until now. I replaced the transmission fluid about 10,000 miles ago.
2000 Passat GLS V6 Manual Transmission 102k miles
I was stopped at a light tonight making a left hand turn, I had the car in 1st gear and the my foot on the clutch. I slowly released the clutch and proceeded to make my left hand turn, halfway thru the turn the car made a noise that sounded like a pop (almost as if something came apart underneath the front end of the car and was loose) and then my manual transmission went into neutral. I slowly coasted to the side of the road and had the vehicle towed.
After I had coasted to the side, I tried putting the car into gear and the engine would rev up but the vehicle would not go forward or reverse. I tried all 5 gears and reverse. While sitting there the car would beep and the screen would say "hand brake on" and if I put the car into first this message would go off. The message only came on about 2 times in 5 minutes and never stayed on.
My 1995 1.8L Corolla wagon (230K original) automatic transmission will shift to neutral while I am driving. It will do this at any speed. It lasts for one to five seconds. Otherwise it runs and shifts perfectly . It does it on level or graded roads, maybe one to five times per week. I no longer feel confident to drive it. At first I would be driving along and the speedometer would go to zero. This would last for one to three miles. Then, after this, the speedometer would go to zero and the overdrive light would go on/off, and the transmission would shift back and forth. I changed the VSS but it did not fix the problem. Now it does the same again, only the transmission shifts to neutral.(The lever stays in Drive) This lasts for one to five seconds. Moving the shift lever during this time has no effect.
View 5 RepliesI have a 94 E350 with the 5.8 and E4od trans. The main issue I am having is the thing will just go into neutral driving down the road. It only happens for about a second. The engine revs up and I back out of the throttle and it will hook back up. It sometimes does it as it is shifting up through the gears. It also sometimes does a real hard 1-2 shift and sometimes downshifts when there is really no need. I took it to get the codes read today and there was nothing.. It is so frustrating and I baby the thing all the time because I don't want to be hard on the throttle when it loses drive.

I'm a new owner to my first 4x4 vehicle. My vehicle is a 2007 f150 xlt. Today while I was driving into work I had my vehicle in 4wd high. As I was going down hill I let off the gas and started braking. When all of a sudden my 4wd drive switched into neutral. I am wondering what could cause this to happen and whether it's an issue or not? It is snowing which was my purpose for being in 4wd.
