I don't believe in power flushing the transmission. Here's some threads that may be of interest:

This is about the best rebuttal post on the benefits of flushing around here:

I guess I'd want to nail down whether your procedure really was a power flush or just a fancy fluid change without any pressure. Plus if your tranny doesn't fail in the first week after flushing, that's probably a good sign.

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.

Could you let me know if your Villager has a screen or filter and what the interval for the fluid change is? (Maybe Steve would know this also) I haven't done anything with the tranny on my '01 Villager withe 54K and was considering changing the fluid and filter. The owner's manual covers like every ford transmission for the maintenance intervals and I don't know what transmission I have.

The maintenance schedule in my service manual says to inspect the fluid every 12 months/ 15,000 miles for normal service (schedule 2). Same interval for schedule 1 but if you tow, use a camper or car-top carrier(?) or drive a lot of rough, muddy roads, then change the fluid every 30,000 miles. I don't know where they cut and pasted the camper/car-top stuff from since you can't put a camper shell on a minivan (unless you want to be a YouTube star!).
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?

Thanks for the info Steve. I checked my fluid and it looks clean and red. I'll probably change it next spring. I see by the dipstick it uses Mercon/Dexron 3.
#11 of 55 '99 Nissan Quest GXE rpm and shifting issues
Jan 29, 2007 (1:02 pm)
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.

Hey Hugo, I'm not a tech but I have a manual for my '99. The shift is regulated entirely by electronic signals transmitted by the revolution sensor and throttle position sensor. Those signals control a couple of solenoid valves. There's a bunch of stuff to troubleshoot from there, but the throttle position sensor is often one of the first things on the list.
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.

#13 of 55 reverse problem on mercury villager 94
Mar 20, 2007 (3:40 am)
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...
