Were/are the automatic transmissions for post-2000 Nissan Frontier pickup trucks really that bad?
They aren't as bad as Nissan cars it is a 5 speed auto in rear wheel drive form they can last sometimes but in the 2000s they had this coolant leaking issue in the radiator which could destroy the transmission but some years were perfectly fine. Not as good as a Tacoma but certainly bang for your buck. Look at Scotty's videos on best trucks to buy and he has the Frontier on it.
The intermix was only a concern from 2005-2007/8 before that those trannies never had problems
that is correct and more specific @r4nier 5 speed rwd transmissions were pretty good
Yes. Nissan is well-known for their transmission issues, especially their CVTs. I believe the frontiers use the 9-speed automatic...look at GM's 10-speed automatic having issues. It looks like the more gears they add, the more problems it also adds lol.
Correction: the new frontiers are equipped with the 9-speed. The older ones are equipped with 5-speed trannys. Apparently a big problem with the 5-speeds was with coolant mixing with the ATF heat exchanger inside the radiator...some people may what I said about these radiators being a bad design.
Ok buddy here is some info. The coolant issue was solved somewhere around 2008 2009 or so, and the 5 speed autos in RWD form were perfectly reliable exept for that problem.
