Automatic Transmission problems of the 2005 Nissan Frontier

2005 Nissan Frontier. Consumer writes in regards to malfunction in the radiator leaking, that resulted in completely damaging the vehicle's transmission.

Dear sir or MA'am; I have a Nissan Frontier 2005 v^ 4. 0l engine nismo 4x4 model. It has 91k miles in it and have recently been experiencing sluggishness and a "thud" while in low power (automatic transmission). So I have been reading forums and online sites to get an idea of what the source of the problem maybe. Mechanics and auto part stores have diagnosed it as an issue with the transmission brake control valve (internal). My trucks discrepancy might be isolated but what concerns me goes not only for my vehicle but also and more for all these consumers who have reported problems with their radiation+transmission. They have spent money and it seems from their comments Nissan dealerships and company have not been able to help or address a known issue (it sounds like a cover-up--hopefully the consumers are accurate in their description). What further concerns me is that they seem to be stuck with their situation and unable to go further. One consumer contacted a local tv stations consumer affairs section and got help. So it seems that what these consumers need is backing from a legitimate institution or agency. If the dealership/company will not listen to their costumers and address the issue (which I believe is a safety issue), perhaps we can get your (NHTSA) help. I propose that NHTSA pls look into this mechanical safety concern and look into possibility of poor materials/manufacturing of some of the Nissan Frontier components. Appreciate your response on this matter. . Read more...

Gradual failure of transmission due to ruptured transmission cooler inside radiator allowing coolant into transmission fluid. Symptom started as small vibration and numerous service attempts could not identify problem. Had transmission flushed and service center did not mention any discoloration of fluid or other problem. Had radiator drained and flushed and thermostat replaced,service center did not cite any discoloration of fluid. Transmission now bucks heavily and web research uncovered the problem with similiar make and model vehicle.

Vibration occurred while shifting. Took to dealership pf which they stated problem related to engine coolant getting mixed with transmission oil due to failed cooler inside radiator. Costs for rebuilding transmission over $6,000this is obviously a manufacturing or design defect, nothing to do with normal wear and tear. Nissan will not reimburse the repair.

The contact owns a 2005 Nissan Frontier. The contact stated when traveling at speeds of at least 45 mph, the vehicle would exhibit unusual shaking and hard vibrations. The dealer advised the coolant was leaking into the transmission and both the transmission and the coolant system would need to be replaced due to cross contamination. The vehicle was no longer being utilized. The VIN was not available. The failure and current mileages were 91,000.

The contact owns a 2005 Nissan Frontier. The contact stated that there was an internal leak in the radiator while spilled onto the transmission and caused it to fail. The vehicle was taken to an authorized dealer who stated that the transmission and radiator needed to be replaced. The contact called the manufacturer who offered no assistance. The failure mileage was 150,000.

I had to have emergency service to the u-joints. Strong vibration under driver seat, afraid to drive any further. Peruzzi Nissan refusing to reimburse a warranty part.
