Replying to: dtownfb (Nov 09, 2006 9:38 am) The shop told me they had a new machine to flush the fluid. After it was done I mentioned it to my brother-in-law and he said they probably didn't change the filter or gasket. So I called the shop and they said that newer transmissions are more advanced and don't need the filter or gasket changed until the vehicle has high miles or if there is a leak. He also told me the machine they use goes directly through the dipstick. I imagine it must have been a "power flush". My transmission does seem to be shifting OK. Does your Quest shift very quickly at low speeds? In normal acceleration mine is in 2nd gear at 10-15 MPH an in 3rd by 30. Unless you think there is a chance the trans was damaged due to the machine forcing clogged particles in the wrong places, I won't worry. On the other hand, maybe its worth doing a regular trans oil filter and gasket change somewhere else to be sure.

Plus if your tranny doesn't fail in the first week after flushing, that's probably a good sign.  Steve, Host SUVs and Speed Shop

Replying to: steve_ (Nov 09, 2006 12:01 pm) Thanks for the posts. This is all I needed to know. Now I will check my Haynes manual to see if it has a screen or filter. If it has a screen, I'm OK. If not, I will have another change done to replace the filter. Luckily I'm doing this at 30K. At 70K I'd be a lot more worried.

Replying to: toomanyfumes (Nov 12, 2006 8:08 am) I don't see anything about being able to clean or replace a transmission (or automatic transaxle) filter or screen. A couple of the diagnostic flow chats have you remove the pan to check the condition of the fluid and the book also says that if you change the fluid and it's dirty, to change it again until the fluid is clean. There is a magnet in the tranny pan. The owner's manual may say something different? Steve, Host SUVs & Speed Shop

Howdy all of you, I have a problem (maybe more than one) that I am trying to troubleshoot on my '99 Nissan Quest GXE (111 000 km/69,000 mi). The MIL is on. The engine has begun abnormal harsh shifting during 1-2 and 2-3 upshift and 3-4 (overdrive) doesn't engage while driving at 70-80-100 kph (43-50-62 mph) and even more excessive speed. I fact shifting occurs at abnormal higher speed. 2 weeks ago, another problem occured. I was not able to drive because rpm was fluctuating between 2000 and 2200 with a speed limit of 20kph (12 mph) even if I step on the accelerator. I borrowed a scantool and code scanned the vehicle and came up with the following fault codes: P0105 - Manifold Absolute Pressure/Barometric Pressure Circuit P0325 - Knock Sensor 1 Circuit Malfunction (Bank I) P1605 - A/T Diagnostic Communication Line P0446 - Evaporative Emission Control System Vent Control Circuit P1400 - EGRC Solenoid Valve P1705 - Throttle Position Sensor Circuit A/T P1105 - MAP/BARO Pressure Switch Solenoid Valve P1490 - Vacuum Cut Valve Bypass Valve (Circuit) I started troubleshooting the Nissan Quest 1999 service manual borrowed from the dealer which I don't have anymore. I checked the absolute pressure sensor power supply. 1. Ignition switch "ON". 2. Voltage between terminal 3 and ground with tester is 0.4V (should be approximately 5V). 3. Detect malfunctionning harness connectors (looks OK). 4. Detect harness for open or short between ECM and absolute pressure sensor. Short (or continuity) exist between terminal 3 and ground. My question are: What can cause the harsh shifting problem? What should I troubleshoot first? How do I locate the short between the sensor and the ECM? Recently, another problem occured: the radiator fan is running continuously (meaning 100% of the time). I think it is related to the thermostat but I'm not sure and would realy appreciate any suggestions/answers any of you could give me. I am on my own with this and am seeking some Nissan expertise to try and get my Quest back to running good. Thank you in advance for help you may be able to give. Sincerely, Hugo

Replying to: supernet (Jan 29, 2007 1:02 pm) Check out the Online Repair Manuals links and see if you can access any of them. I didn't see any help at the AutoZone link but I've had good luck with the Auto Repair Reference Center. Maybe a library in your area subscribes to it. You may want to check out the Transmission Traumas? and Cooling Systems: Problems & Solutions (Radiator, Fan, etc) discussions too, and hopefully someone knowledgeable will show up in here soon.

| hello, can someone help me out on my mercury villager 94 problem. my mechanic had to take down my transmission to replace a leaking freeze plug, so he drained the xmission fluid on the torque converter, then filled it up, when the everything is back in place, I had this reverse problem... evrytime I step on my gas and execeeding the RPM to 1300rpm the RPM/(tacho meter) goes up, even though the brake is already applied, the van will not stop coz' the RPM never drops, so I have to put it to nuetral to be able to brake. But reversing is ok when RPM is below 1300rpm, as long as you don't step on the gas to hard. And also if you are reversing in an inclined position with out stepping on the gas the RPM also goes up. Can someone please help me out. thanks... | |
