4WD V8 LE

2005 Nissan Armada • V8 4WD Automatic • 126,815 miles

I have a 2005 nissan armada and recently it gave me some trouble codes with p1759, p1757, p1841, when I test the car the the upshifts are good all the way to 5th gear but when I reach a stop light the car does not downshift at all. The car stays on high gear. I have to shut the engine in order for it to reset and begin the same cycle.

DTC P1757: FRONT BRAKE SOLENOID VALVE
DESCRIPTION

Front brake solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then be shifted to the optimum position.

POSSIBLE CAUSE

• Harness or connectors
(The solenoid circuit is open or shorted.)

• Front brake solenoid valve

DTC P1759: FRONT BRAKE SOLENOID VALVE FUNCTION

DESCRIPTION

• Front brake solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then be shifted to the optimum position.

• This is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunction such as control valve sticking, improper solenoid valve operation.

POSSIBLE CAUSE
• Harness or connectors (The solenoid and switch circuits are open or shorted.)

• Front brake solenoid valve
• ATF pressure switch 1

DTC P1841: ATF PRESSURE SWITCH 1
DESCRIPTION
Fail-safe function to detect front brake clutch solenoid valve condition.

POSSIBLE CAUSE

• ATF pressure switch 1
• Harness or connectors
(The switch circuit is open or shorted.)

How was erangel89 's problem solved? I was told I need a new transmission, but don't think it's the transmission. DTC P1757 is code it is throwing. Same exact problem and dealership service center replaced a recalled ECM relay today

Since the P1757 refers to a faulty signal received by the front brake solenoid, make sure the connector is properly connected. If so, replace the solenoid.

Danyuell, refer to the 2 posts above. Check electrical connections first. Then check pressures.

Danyuell, I finally got my 2005 Armada fixed with the codes above which left me with no first gear after stopping. The transmission place told me it is the TCM that is bad. To fix it you have to buy a new valve body. (The transmission shop said do not buy a rebuilt or old one. Buy straight from Nissan as they have upgraded the metal and it is more solid.) The body itself is $1172 labor was $120 and they charged $119 for transmission fluid service for total of $1511. It is now running great, better gas mileage than with no first gear, ha. It was definitely a defective part and I am sending my bill to Nissan in hopes that they will reimburse me, but everyone says I'm wasting my time. I will report back.

My 2006 Nissan Titan was broken down due to a recalled problem. After the dealer installed the recalled ECM relay my transmission malfunctioned. I have a 2006 Nissan Titan. I recently had a problem with my truck not starting and then when it did start it would shut off while driving. I looked online and found that there was 2 recalls on my vehicle that just so happened to be the problem with my truck. I had the truck towed to the Abeloff Nissan Dealership in Bartonsville, PA. The dealership replaced the recalled parts which were the ECM Relay and the fuel sender. When I went to pick up my vehicle after the recalled parts were installed I backed out of the parking spot and drove forward. I came to a stop and when I went to go again my truck had no forward motion (it felt like it was in neutral, engine would rev but wouldn't move forward.) At this point the engine light was on and I hadn't even left the dealerships lot. I went back in and told the service manager what was happening and the mechanic got in the vehicle with me and we drove up the road about 2 miles and it seemed fine. When we stopped to turn around it happened again engine revved but didn't move. The mechanic turned the truck off and then restarted and we were off again. When we got back to the dealership the mechanic put it on the computer and said that the code was P1757 (front break solenoid). Apparently this part is located in the transmission and Nissan no longer makes these solenoids (you have to buy the complete valve body which costs $1200.00.) My truck has NEVER had any signs of a transmission problem before this. I contacted Nissan Corporate in hopes that they would fix this problem that they obviously caused by the ECM relay replacement. Nissan Corporate called back a week later and denied any funds to help me. They stated that the ecm relay replacement had nothing to do with the transmission problem. I went home and researched this problem. I found multiple cases where the same thing happened to other Nissan truck and suv owners. I went back to the dealer and informed them that that I found these other cases and implored them to google this problem. The mechanic was standing there and he said that he did go home the night of the problem and researched it himself and found the same thing that I did. The service manager there was surprised at our findings and said that he would reopen our case with Nissan corporate to try to get this problem fixed. Today, 21 days later I got a call from the service manager at the dealership and he informed me that Nissan Corporate denied my claim again based on the year of the truck and the mileage (122,000). I asked how that was fair when it has nothing to do with the mileage on my car. Had I gotten the recall notice from Dec 2010 I would have gotten the work done and my mileage would have been 63,000 (I know that because that is the year I bought my truck). To replace the valve body it will cost me $1685.00 for parts and labor. This recalled ECM relay was installed on Oct. 10th and transmission problem was right after that on the same day. My final answer of denial came yesterday, Nov 4th. It has taken 26 days for Nissan to decide that my vehicle is out of warranty. I have had no work performed on my vehicle due to their delay yet my payments keep coming. My contact at Nissan corp. Was Jennifer (regional specialist) ext. 457210. Or Sue the escalation specialist. Case #12334061.
I would love to get in contact with other Nissan owners with the same problem. Please email me mpastor25@yahoo. Com

I have the same problem started one week ago and they told that I have to rebuild my transition and I am in Saudi Arabia and we have change of woner ship of the Nissan Delar and we never had any recalls in Saudi and you can say all you want no body is going to listen to you or even look at your car and it would cost over 4000usd to rebuild the transition.
