In an automatic transmission there is a ring with teeth on the output shaft of the transmission. When the transmission is shifted into park a lever called the parking pawl is lowered against the ring. If the parking pawl did not land squarely into an opening in the ring the car will roll slightly and there will be a usually an audible click. The parking pawl ...

As @ᴘᴀᴜʟsᴛᴇʀ2 said, this appears to be a known issue with Honda Odyssey Model Years 1999-2001. From the Wikipedia entry for this set of model years: The 4-speed automatic transmission in 1999 to 2001 models had serious problems with transmission durability. Honda spokesman Mike Spencer stated that four-speed models were afflicted with a bad bearing ...

Your question is incredibly board because it can be broken into 5 distinct aspects; planetary gear sets operation, clutch and band operation, torque converter operation, control system operation and the power flow through the transmission. Further complicating the answer is that there are hundreds of different types, kinds and transmission manufacturers. For ...

NO GO You won't be able to tell if he is being honest. Oil in a radiator is a sign of a blown head gasket. A blow head gasket requires the following to repair if the head is ok and not warped. Remove all fuel injection or carburation. Remove intake manifold Remove exhaust and manifold Remove valve cover and cam sprockets (if it's an overhead cam) Remove ...

Given the description of the problem, I think the comments are exactly right, this is an issue with your transmission. Now you need to determine if it's just fluid level, or if there is something more serious going on. Couple of things you can do, first, follow the instructions in the comment by @DucatiKiller. That will get you into the proper fill level. ...

The stalling at high speed could be a variety and/or combination of things: clogged fuel filter, dying fuel pump, collapsing rubber fuel line. The need for a high fuel flow (engine demand) can cause old rubber fuel lines to collapse (Bernoulli effect). Fuel pump or fuel filter are self-explanatory. The Celica is fuel injected. If you uncap your gas tank ...

Old automatic transmissions were shifted entirely using hydraulics, not electronics. For this operation the transmission would generate 3 pressures; line pressure, throttle pressure and governor pressure. Line pressure is generated with the front pump of the transmission. It is used to actuate clutches and bands. Throttle pressure is a derivative of line ...

Ok...my suggestion on starting this is. MUST BE A VERY CLEAN DIRT/DUST FREE AREA Don't flush ... Start to change the fluid and filter as recommended. When you take down the pan loosen the bolts in a left then right then left order all the way around. Just loosen them.. Go back and slowly open the bolt patter and you will see the pan lowering.. It may be ...

Well - most older cars that didn't have a TCU used manifold vacuum to determine shifts. When one of the vacuum hoses broke or fell off, the transmission wouldn't shift properly. But this won't be realistic for your bicycle - you'll have to write some software and figure out an algorithm that will work - using some speed and torque sensors. It's new ...

As a best guess I'd suggest the transmission is doing okay. Your driving the vehicle as you have been is not only good for your Eurovan, but for any vehicle in general with an automatic transmission. I don't think there is anything inherently wrong with the transmission from the way you describe things. This is just my opinion which is just based on your ...

Keep in mind that you can have a low battery and not be able to crank the engine, but still have enough to run some of the interior electrical parts like the one you mentioned. The fact that it's only been an hour since the car last ran makes the soft battery a likely candidate. The key (as mentioned in the comments) is whether the engine is cranking or not. ...

I've brought it to the mechanic yesterday and I got an update thru the phone that the problem was a P0700 error code that was thrown. He mentioned that before he continued to check the tcm he noted that even though the transmission oil was red, it was not feeling like oil(there is no water mixed but the oil feels less oily, based on how he described it to ...

Pulse Width Modulation (PWM) can easily be achieved with two wires. All PWM does is hold one wire constant and rapidly pulse the other between 1k and 10k times a second. By changing the relation ship of how long the pulse is on versus how long the pulse is off the duty cycle is changed. Both the wires from the pressure control solenoid go to the PCM. The ...

How much should I use? As much as you need to get it back up to operating level if you plan on driving it any more. If you don't get it up to the proper level, you'll be burning your soft parts up (clutches/bands) and risking the more expensive hard parts (planetaries, sun shell, sprag). Would the take care of the problem or am I looking at a more ...

What you describe is a common symptom of a dirty or contaminated oil filter! I am speaking of an "automatic transmission fluid" filter. it is similar to a motor oil filter except it filters "ATF"instead of Petroleum oil! When the filter is dirty or contaminated it Beaks down to a Thinner less effective consistency. At that point it can't develop enough ...

I have this same problem on a 1999 Dodge Ram 4x4. Didn't start doing it Until it had 50,000 miles on it. The 1999 has only one oxygen censor and throttle body. That said, itss not not a vary smart electronic system so I wouldn't think the system has a limp mode. I also remember years ago that a deep snow broke a plastic vacuum line under the trany that ...

In addition to the port being disconnected it is possible that the CEL bulb in the instrument cluster has blown, which would explain why you are not seeing it light up when the key is turned to Ignition On. The transmission control module is usually separate from the engine control module.

There is no way a 2011 car can run without the engine ECU, unless the engine has been swapped for something from 70s.
