Need help with 727 transmision?
I have a 1990 Dodge Cummins with a 727 transmission. It starts in drive and reverse lights are always on. Mechanic said it was something inside the transmission (he tried a neutral safety switch and it didn't do anything. It also takes a bit of work to shift through the gears. It doesn't want to change gears, like something is binding up. I think these problems are related. I am being told it's the "rooster comb" and some plastic thing up in there that actuates the neutral safety switch is probably broken. It's above the valve body... Can I get to this thing from underneath the car leaving the tranny in? Just working from where the pan goes? Is it "staked" in and what's involved in removing it? It also likes to "creep" very little when I first turn the truck on after a long sit. Maybe it's going out? If so I'd just wait til the tranny went all the way out and did a total rebuild?
Why won't my transmission go into park?
It's an automatic trans for 1994 camaro, I know the transmission has a slow leak so it might have emptied but I usually fill it up enough, and I can usually tell when it's low because it starts slipping in gears. When I try to put it in park it just stops and won't move, how can I fix this? And what's wrong?
Why does a car engine with an automatic transmission idle at a higher RPM in park than it does in gear?
There is no manual clutch in an automatic transmission but there is a fluid coupling in the transmission called the torque converter that does the same thing. It allows the transmission to be stopped in gear with the engine running. It's basically two vaned wheels with fluid between them. At idle the fluid at the driving end does not move fast enough to turn the output wheel. When the engine speed increases the fluid starts to transfer its energy and it will speed up the output to the same speed as the input. (Minus a little slippage) So when you pop the transmission into gear the engine is slowed down a little because it is spinning the torque converters fluid. There are a few different transmission types out there including CVT (continuously variable transmission) which use different clutching mechanisms.
While stopped in traffic whilst driving a car with CVT transmission, does selecting drive and applying the parking brake significantly damage either the parking brake or the CVT transmission?Can you explain the mechanism of the pulleys and belt system in CVT transmission during driving and braking?
Neither the parking brake nor the CVT gearbox will take harm from this. Each CVT features some sort of clutch, which disengages the CVT from the drivetrain while the vehicle is at standstill. Cheap CVT vehicles (for example motorscooters), have a flywheel clutch, which opens as soon as the engine is at idle. More expensive CVT vehicles (which "creep" in D-position) feature either an electronic controlled clutch or a torque converter. These gearboxes are designed to stay in D position during shorter breaks.
Adjusting steering wheel Ford ranger?
I felt the plastic part that holds the steering wheel to the car and didn't feel a lever or anything, is that where I would look? Under the wheel? I hope it has one cuz I'm short and the wheel seriously interfers with me checking my speed
My Dodge Grand Caravan rolls when its put into park! is it the transmission, linkage or what? please help?
Does it roll a foot or two or will it keep moving? If it keeps moving you just need the linkage adjusted, it's not going fully into park. Most cars will roll a little.
Should I always put the parking brake on—even when I'm parked on a flat surface?
Yes. I was once was driving down a frontage road in the middle lane of three lanes alongside a tollway. As I was driving through an intersection, several hundred feet ahead I saw a pickup truck dead stopped in my lane without its emergency flashers or brake lights on. I moved to the left lane to get around it, and saw that it was unoccupied. There was another pickup truck right behind me. I watched my rearview mirror, and he must have been distracted or something, because he ran smack into the stalled pickup without seeming to brake at all. The impact caused the stalled pickup to roll in a wide arc up over the curb and about 75 feet into an open field next to a gas station. Evidently, whoever was in the truck when it stalled did not have enough sense to coast over to the curb. He/she evidently left the truck in neutral without the parking brake on. If it had not been an empty field, but something like a gasoline pump, an old man sitting on a bus stop bench, or an occupied baby carriage that the truck ran into, a tragedy could have occurred. I circled around and drove back, expecting to see a seriously injured driver in the second truck. He evidently had been wearing his seat belt, was unhurt, had managed to brake a little bit, and was walking around in the street picking up broken glass. Any unattended vehicle should have its parking brake on.
Is my transmission out if it won't go in drive but will go in reverse?
My truck has a similar problem, so I will attempt to answer the question to the best of my ability. But first, answer these questions: Does your vehicle shut off when you put it in drive (or any other gear[park is excluded])? Notice any abnormal smells? Next, look under the hood and check the dipstick (do NOT turn off the engine while doing this) run the engine until it is warm either in park or neutral. After rubbing the dipstick, fluid should run pinkish and almost clear and should be sweet or tart when wafted— if your fluid has a burnt toast smell and is brownish, take the vehicle to the mechanic. Check to see if the fluid is betwixt the ‘add’ and ‘full’/‘hot’ and ‘cold’ marks— if you are near the ‘add’/‘hot’ mark, flush out the old fluid and replace with new fluid until full; if you overfilled (which you probably did), you will have gear shifting trouble and your oil will be depleted. My advice is to siphon out the fluid completely and refill the transmission until full.Signs of a Failing TransmissionWhat Happens When Too Much Transmission Fluid Is Added - Driving Life
Why does my engine shut off when I put it into park?
this happened on my ex-wifes car all the time - it's probably the lockout cable on the shifter (that keeps the car in park when the key is removed) ... have it inspected by the garage when they do the oil change, and trans fluid service. **edit** The Park / Neutral safety switch ONLY interrupts the signal to the starter - this prevents you from starting the car in gear. Ask your Ford dealer if you don't believe me.
Is it bad to put your car in Neutral at a red light?
When you shift into neutral you release the transmission load from the engine. Without the transmission load your engine should idle down a bit and saving you about a drop of gas. When you shift the transmission back into gear you return the transmission load to the engine. The computer control adjust the engine management system to handle the transmission load, the engine power is absorbed by the transmission with drive force being carried from the transmission to the drive axles, to the wheels. Compare the drop of gas savings against the wear on the the transmission, and drive train. Although very minute the wear is there, the transmission must adjust to the engine torque and that takes a second and that torque is transferred to the drive wheels and back. New vehicle have taken this into consideration, for example VW & MB Blue tech or blue line engines and transmissions that are made to shut down when stopped for a longer period. What happens is that the computer controls the shut down and does not release the tension of the engine torque but holds it, the complete drive train remains under tension so when the engine starts up again there is not jolt to the drive train. This is more than what you asked for the difference is very minor, however whenever you put a car in gear the entire drive train receives the torque of the engine. When you leave the car in drive the engine torque remains and is not interrupted. That is the only difference I am aware of.
