I need to know what PO760 is ?

Question:
I need to know what PO760 on a 97 chrysler cirrus and where would that be on the car ?

Answer:
P0760....Shift Solenoid 'C'
This fault code is a solenoid circuit failure in the transmission
most times when seeing this fault code it is either a bad transmission control module or the transmission solenoid pack
both parts are expensive and should be tested with a scan tool

GM Dex-Cool/ Intake Manifold Gasket Class Action Lawsuit Settlement Reached March 20th, 2008

NATIONWIDE SETTLEMENT REACHED IN GM/DEX-COOL CLASS ACTION LAWSUIT
On March 20, 2008, the California Superior Court granted preliminary approval to the class action settlement reached with General Motors in the GM/Dex-Cool class action lawsuit. This settlement affects people who purchased or leased a “covered vehicle” anywhere in the United States other than Missouri. A separate settlement has been reached for those who purchased or leased their vehicle in Missouri, which will offer the same benefits but will be separately approved by a Missouri court.
The lawsuits were filed on behalf of owners of General Motors vehicles, which were factory-filled with “Dex-Cool” coolant. In summary, the lawsuits alleged that Dex-Cool degraded certain vehicles’ intake manifold gaskets and other engine sealability components, and that in certain other vehicles, Dex-Cool formed a rusty sludge, clogging the vehicles’ cooling systems and causing vehicles to overheat.
Terms of the Settlement:
You may be eligible to receive between $50 and $800 in cash reimbursement under the settlement if you have paid for a covered repair by May 30, 2008, and if you submit a claim by October 27, 2008. If you paid for multiple covered repairs, you may be eligible to receive multiple cash reimbursements provided you submit a separate claim for each repair.

Have had it at the dealership

Question:
Have a 1995 Jeep Grand Cherokee automatic with 226,000 km on it. Have had the starter replaced but still have problems starting jeep. Will start okay a few times but then will need to try up to 5 times (turning the key - no noise but lights on dashboard come on, etc.) before it will start. Any suggestions on what the problem could be?

Already Tried:
Have had it at the dealership - they replaced starter but that did not help at all. The start problems usually happens when the car has been parked for less than an hour but this week it started even when parked overnight. It will be okay for about 4 time parked but then will not start. Have to turn the key in the ignition a few times before it catches. The dealership has no idea what the problem is as the car works okay when it has been left there (left twice, overnight for them to test during the day, etc.) Any ideas would be appreciated.

Answer:
I would definitely suspect you have a problem either with the cables for the starter. Or you have a bad or failing starter relay. But lets get the OBD or on board diagnostics. They can often point in a good direction.

Here is general procedure for getting engine codes by using the flash method.
Turn the key from off to on three times within five seconds. Then watch the CHECK ENGINE lamp. (odometer on digital odometers will show codes not flash) When you hit the proper rhythm ( this varies some from vehicle to vehicle and takes a few tries sometimes ), the MIL will stay lit longer than normal, go out and then start flashing.
Count the flashes. There will be short pauses between sets of flashes to indicate you're going to another number. The last set of flashes will always be 5-5, or code 55, which means end of test. All the codes will have two digits to them. You can repeat this as many times as needed to get a feel for how it works. If the PCM or battery has been disconnected within the last month or so, the first code you'll see is 1-2 (code 12) which indicates a recent loss of memory. be careful not to misread numbers so like 1-2 becomes a 3 or 2-3 becomes 3-2. Do this a few times to check and always write them down for future reference. Remember these codes do not say parts are bad only that they got or receive a bad signal. SO it maybe part before or after them that needs to be replaced.

1984 Honda Accord. No spark at the plug.


Question:

1984 Honda Accord. No spark at the plug. Timing belt replaced six weeks ago.


Answer:

Unplug the coil wire at the dist. cap and see if you're getting spark from the coil wire.
If not then you probably have a bad coil or ignitor.

My Car Eats Batteries!!


Question:

2001 Chevy Impala mileage: 55,000. Hi...my girlfriend's old Impala eats batteries! We had one burst last month, thought it frozen. Got a replacement, now this one is belching sulfurous gasses and is warm to the touch after the car has run for a little while. Not cold enough to freeze - possible charging system problem? Sometimes the interior lights/radio lights go dim, then bright again, also. The alternator is putting out about 14.7 volts, the battery is charged to about 13.5 volts, seems high. I thought maybe the voltage regulator could be bad, but don't know where it is on that year vehicle! Otherwise a great low-mileage nana car...any advice you guys could give on where to start looking for the problem would be appreciated!


Answer:

Check the ground wires to make sure they are in place and making good contact, especially the battery cable ground connection to the motor. If this checks out okay, you probably have a faulty alternator. BTW you will need to replace the battery again also. It cant take over charging.

Starting - Accelerating problems


Question:

'99 Acura Integra GSR 97,000miles. The problem started with what i thought was just bad spark plugs. The car would occasionally misfire when i gave it gas. I changed the spark plugs and the misfiring increased and the car became almost impossible to start. I pulled the plugs and checked the gaps again and the plugs where dark and saturated with fuel. I also noticed while trying to start it again several minutes later that you can smell strong gas almost immediately after trying to start it. it seems to idle fine when it does start, but as soon as you tap the gas it either stalls are comes close to it. It has good spark also.

Answer:

Just a thought, but plugs wires come to mind. Especially when you said it ran worse after the new plugs were put in. Tugging and pulling on those wires breaks down the composite conductivity of the wires. The hesitation is also a symptom.

1997 Ford Taurus Starter problems


Question:

We replace the starter but when we went to put the positive cable back on the battery the starter started to crank without the engine being turned on. Did we put the starter on wrong?

Answer:

The problem is that on the back of the starter there is a small wire that goes to the "s" terminal and The positive cable. The positive cable is touching the small wire , so the Starter is getting power on the "s" terminal wire and thinks you want the starter to crank. Separate the two wires from touching and all should be fine once more.
