El vehiculo coje la reversa pero no el drive y no quiere arracar no la puedo usar ni mover hacia frente

I was driving on an interstate at normal highway speed when the car shuddered as if going over rough pavement. the engine started racing, but the car gradually lost forward propulsion. i steered to the emergency lane and stopped. after a minute, the car regained just enough forward motion to get me to the next exit, across an intersection (where the light just happened to be green, thank goodness), and into the parking lot of a large grocery store before the vehicle lost all propulsion. we pushed the car the last few feet into a parking spot. it was towed to a nissan dealership. i was told the next day that the transmission warmer had failed, allowing radiator coolant to leak into the transmission, which ruined the transmission. the repair would cost $6000. i cannot put another $6000 into a 13-year-old vehicle, even though i've only had it for five months, so now i've lost the money i put into it and will have to start over with another vehicle.

Transmission is failing quickly. i had to replace my radiator a few months ago because it cracked. that event left my wife and children stranded on the interstate.

Radiator failed causing leak of radiator fluid into transmission causing vehicle to be towed to auto shop. vehicle was in motion on highway and then would all of the sudden no longer accelerate. mechanics, (got 3 estimates) all said same thing; that this was a problem with these pathfinders. my cost is about 6,500. i had just bought this vehicle for 8,500 about 3 weeks prior.

There is a system design flaw with the 05-10 nissan trucks; pathfinder, frontier, xterra. the radiator houses both coolant and transmission fluid. when the radiator fails, it leads to coolant and transmission fluid mixing; resulting in catastrophic failure and premature destruction of the transmission. our transmission was replaced with a brand new transmission after the original transmission failed at 89k miles. after the new transmission was put in, the transmission was destroyed at 90k miles and the issue was traced back to a cracked/ruptured radiator; leading to mixing of coolant and radiator fluid which in turn ruined the transmission. the cost of the initial transmission replacement was $6000; the estimated cost of replacing the transmission again along with the radiator and flushing the system and replacing the fluids is $8000. in both instances of transmission failure, it happened during driving conditions on a highway without symptoms of transmission issues. the worst part of this is not the cost. the worst part is that this known issue on nissan trucks should have been classified as a recall issue because the failure can happen anytime, especially during driving conditions and has the potential to cause a crash, serious injury, or death.

My vehicle suddenly started to have a delay in acceleration when the gas pedal was pushed, and then would catch and lurch forward. i have been told that the transmission inner cooler ruptured and has ruined both the radiator and transmission. further research indicates this is a known issue that nissan has failed to accurately advise owners about, or issue a recall. this is negligent and wholly unethical. negligent in that the symptoms could lead to serious harm out injury, as there is no warning prior to the damage being done. unethical in that now nissan gets to profit from their negligence, as it will cost $5,000 to remedy what could and should have been much less costly.

Tl* the contact owns a 2006 nissan pathfinder. the contact stated that the "overheated" warning indicator illuminated while driving approximately 25 mph. the following day, the vehicle failed start. the vehicle was towed to an independent mechanic who determined that the radiator failed and caused coolant and transmission fluid to mix. in addition, the transmission control module failed. the mechanic stated that the engine had to be rebuilt and a new radiator needed to be installed. the dealer and manufacturer were not notified of the failure. the vehicle was not repaired. the approximate failure mileage was 87,270.

Car overheated/no start, had suv tolled to auto repair shop was told by techician was told the following. radiator failed causing coolant and trans fluid to mix. transmission control module failed causing vehicle not to start.

My problem is with the radiator and transmission fluid contamination.. some hoses inside the radiator that carries transmission fluid and coolant cracked and contaminated both the radiator and transmission. this problem has caused my vehicle to lock into 4 wheel drive and contaminated both my radiator and transmission this problem will need to be repaired before the vehicle can be driven. it will be a costly repair that should be covered by nissan on a recall according to all the complaints i have read about.

Transmission has went out due to factory default there's a recall on the exact issue that i'm having with my car i need to know if there's an extended warranty or something to remedy this because it seems to be a known issue

Radiator malfunction cracked transmission lines, mixing antifreeze into the transmission lines, contaminated the transmission, the transmission is ruined! never informed about this defect in the radiator! never no recall!

Catastrophic transmission and radiator failure due to co-mingling atf and coolant at 136,000 miles. contacted nissan north america, they refused to help in any way, but acknowledged this as a "known" issue.

The radiator has broken and leaked into the transmission causing a complete failure in the system. both must now be replaced.

All 4 of my catalytic converters have had to be replaced (or need to be replaced - i've already replaced bank 1. now bank 2 is bad) in the past 12 months or so and now my radiator is leaking into my transmission. i discovered there was a class-action lawsuit on the radiator/transmission issue, but i'm outside of the warranty period. with respect to the catalytic converters, i occasionally smell exhaust, but the check engine lights stay on. with the transmission, it started out as gear slipping, causing rough driving (which the dealership told me was the catalytic converter). then, it started running slow out of first gear and hard shifting. i took it to a transmission place that pulled transmission codes and when they dropped the pan, the fluid looked like a milkshake. the rough driving/gears slipping didn't matter - it could be on the highway or in the city. i don't know the exact date in 2018 that i had the issue, but i've been dealing with this issue for a year.

The transmission would not shift into overdrive, so i took the vehicle to aamco. the transmission was contaminated with coolant from the radiator, requiring a complete overhaul including the transmission computer. estimated cost of damages is $4600! my vehicle is in excess of the extended warranty, however this is a design flaw that should be corrected by nissan.
