I have 2008 frontier SE 4.0 liter with transmission cooler located in the radiator and it has failed 2 (2 x new radiators) leaking tranny fluid into the radiator and getting water in my transmission. had to buy a remanufactured transmission and putting an external transmission cooler on. :crying:
"parts & labor nearly $5,000"
Automatic transmissions in certain 2005-2010 Nissan SUVs and Trucks are under attack from their radiators. Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it.
The widespread issue has prompted the North Carolina Consumers Council (NCCC), a consumer protection group, to plead that everyone avoid the 2005-2010 Frontier, Pathfinder, and Xterra at all costs.
The Strawberry Milkshake of Death
Ruptured radiator cooler tanks are forcing coolant into the five-speed automatic transmission through the cooler lines. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion.
The liquid is known as the strawberry milkshake of death (SMOD) and it’s not because it tastes good (please don’t taste it).
In June 2012, NHTSA was petitioned by the NCCC to investigate the issue. The key to the petition was proving a safety defect existed, something Nissan has continually denied. NHTSA only forces automakers to issue recalls when there’s a safety risk involved.
NHTSA found that the radiators are defective without a doubt.
“When examined under a microscope, cracks and fractures were observed at the lead points. The other three non-leaking transmission fluid cylinders were inspected under the microscope and five of the six transmission fluid port areas were cracked.”
However, they didn’t find that the majority of complaints represented a safety risk and closed their investigation. That means the only hope for a recall is up to Nissan. Cue the sad trombone.
The Warning Signs of Transmission Failure
Some articles online claim that being aware of the proper warning signs may help prevent your Nissan from needing a rebuilt transmission. These warning signs are:
•Heavy Vibration While Shifting
•Heavy Vibration While Accelerating
•Car Doesn’t Warm Up When Sitting
Owners who have had their radiator crack are claiming that even if you catch it early, your transmission is still doomed trouble due to this engineering / manufacturing defect. You can read their stories over at CarComplaints.com for the three Nissan models that are showing the defect:
Perhaps even more troubling is owners who have already had their transmissions “repaired” by an authorized Nissan dealer are still reporting catastrophic transmission failure. Through no fault of their own, Nissan owners who are out of warranty are left to cover the hefty repair bill, which can be over $4,500 when all is said and done
Yes we are aware of this. there is 110 , now 111 pages on it.
