CarComplaints.com Notes: For years, Nissan trucks and SUVs have had problems with coolant destroying the transmission. And for years, Nissan has done nothing about it.
The 2007 is no different than the 2006 and 2005. Just avoid it.
I bought my Frontier and almost immediately noted it was running hot, normal, but on the hot side. Logged into a complaint about it and discovered the radiator and transmission problems. I decided to replaced the radiator with a new all aluminum radiator, I wasn't about to replace it with a new (same) problem but a radiator I felt would keep my transmission fluid where it belonged. Since I replaced it I have not had any issues with either the radiator or transmission. Expensive fix, but if I had waited until it actually ruptured and started swapping fluids it would have been horrible.
