2004 Frontier shift connection quit by mjwinter48

My military son just bought a 2004 Frontier club cab, auto 2WD, with 70K on it. Drove from Colorado to Chicago and it worked just fine. Now, when he shifted it to D, it went to reverse, and now must be in drive, cuz it won't start (obviously not in neutral or Park) Is there a pin or something tht may have let go that connects the shifter to the tranny? Is this easily fixable or does he need a dealer or tranny shop? Can a good reputable mechanic fix it? Any ideas. He needs to get to his next duty station and is on a limited budget.

2009 Frontier downshifting problem? by oralbertr

I have a new 2009 Frontier 4x4 V6 with auto tranny. Have a strange problem - it looks like tranny doesn't like to downshift.
 
Even at slow speed it stays in hi gear, so RPM goes down to about 1200RPM, engine looses power and starts pinging. Is there any way to re-program its ECU to make tranny willing to downshift at slow speed? I understand that it probably tries to save fuel, but I'd prefer it to be more responsive, right now it takes about two seconds after I bottom gaz pedal before it downshifts. It's not only annoying, but it could be dangerous when trying to merge or need to accelerate fast, since engine lacks torque at low RPM.
 
The other problem I have (not sure if it's related) is engine is constantly looking for idle RPM. It goes too low and starts vibrating, then increase RPMs to suppress vibration, then go too low again, and so forth.
 
It's a new truck and problem started from the beginning. I tried to reset computer a few times, but it didn't help. Tried to use hi-octane gasoline, but it didn't help either.
 
Any ideas?

99 Frontier gear shift pops out by thomf

I have a 99 Frontier, 4x4 king cab, V6, 5 speed. In March I had the clutch replaced. Over the last month and a half the gear shift has started popping out of gear when I am sitting at an idle. It does not do this when I am driving. My shop says it might be the synchro gear but would have to drop the tranny to check it out. Oh boy. Is it possible for something else (less expensive) to be worn or out of adjustment, like something in the shifter assembly or something? Thanks

I have a (non-Nissan) book that shows these usual culprits - Worn Shift Fork, Broken Spring, Synchros.

auto tranny hard shifting by frontier_girl

Hi all.
I have an 03 supercharged 4wd frontier with an auto tranny and just shy of 100k miles. As of late, it seems that whenever I am driving through town at a fairly even speed of 35-40mph, when I press or let up on the gas pedal, the tranny shifts up or down harder than usual. I don't notice it at any other speed ranges, and it doesn't throw me to the floor or anything,.. just enough that I notice. I did notice that my tranny may have a small leak underneath, but I check my fluids constantly and it's clear and pink and I've never had to add any.
I don't have a reliable mechanic here in this small town, so when I take it to the big city to have it worked on, I'd like to have an idea of what I'm talking about. I've had enough experiences with repair shops to know that they will often take advantage of me since I'm a girl.
If anyone has any feedback, I'd sure appreciate it.
thanks

Manual Transmission by bcjax

I have a 2003 Frontier with about 90,000 miles on it. I have recently notice that when I push in on the clutch I am getting sort of a humming noise. When I release the clutch the sound goes away. The transmission seems to be running fine, I am having no problem with shifting. Also, it moslty happens in the morning after it has been sitting over night. Any thoughts?

Loud whine at cold temps. transmission? by billyberu

Hi,
 
New to the forum and have a question. I have a 2007 Frontier 4x4 Auto King Cab and last winter experienced a blood chilling whine coming from who know's where. It was so pierecing that we had to stop the truck as I thought a bearing had locked up or something. This noise has only happened twice and both on cold days -25 C to -30 C. The first time it happened I had been driving for a hour already. The noise would get louder slightly the faster I drove but would completely go away below 70 k/hr or ~45 mph. I took it into the dealership and they said they could not reproduce the noise and then said they found some obscure bullitin and something. I do not have the invoice on hand to let you know what they replaced, but I was sceptacle anyways. It happened again a few weeks later on a cold day but I was only a 1/4 mile from my destination (work). I pulled in and it has not repeated itself. Winter is fast approaching and I am getting concerned again. Any ideas out there would be appreciated. We have a old time mechanic at work and he has a idea that a pump is being starved at cold temps.
