Question about 2000 Nissan Frontier
2000 frontier ext cab 4x4. 12000 miles. Transmition is kind fo like going to a passing gear around 65-70 mph then dropping a gear then going to a "neutral" untill i let off the gas then it will catch a gear and i can accelerate for a short period of time before doing it again. It seems to get worse the longer i drive. I am kinda stuck with 300 miles left on my journey and unsure what to do. Thank you.
Unfortunately, you will need to get to a transmission shop a.s.a.p,
because there is a good possibility you "tranny" is about to "go out".
Be sure to carefully check the transmission fluid level right now.
If you have only 300 to go, perhaps you might rent a car to finish your trip whilst someone fixes the problem.
God bless your efforts.

Sounds like a bad overdrive clutch, it's in the torque converter and is not repairable, you have to replace the torque converter, this is somewhat common on high mileage automatics, usualy it sticks locked, when you put it in gear it makes a clang and unlocks, but locks up as you drive and won't unlock when you slow down like it's supposed to
sounds like this one simply will not go into gear at all, either the clutch is worn out (They're vry small snd weak) or possibly a sticking valve body.
this needs to go to the dealership garage, NEVER go to Mr Transmission type places they'll want to overhaul it whatever's wrong, they don't waste time on diagnosis

rear main seal is the leak to fix: drop transmission remove clutch, drop oil pan and replace seal. seal is about 30 bucks, if your not auto savy id let a shop do it.. prolly around 800 tho...

The evaporative emission control system checks to make sure there are no leaks in the lines that run from the gas tank to the charcoal canister and up to the engine. It also checks to make sure the gas cap is sealing correctly.
When you fill your car with gas, the vapors in the tank get forced into a canister filled with activated charcoal. Also, on a hot day as the gas heats up and vaporizes, those same vapors push into the canister where they're stored. But the charcoal can only hold so much vapor. At some point it has to be emptied. The emptying process is called "canister purge." Here's how it works.
The computer orders a canister purge by powering open a purge solenoid. That opens the vacuum line between the canister and the intake manifold. At the same time, it opens a VENT solenoid. That allows fresh air into the canister. So the engine is literally sucking out the gas vapors and purging the canister with fresh air. The computer has to adapt its fuel strategy to take advantage of all the extra gas vapors coming into the engine.
The computer notices the canister is empty when it detects a leaner condition (all the vapors are used up) and it resumes normal fuel delivery. Some car manufacturers then close the VENT solenoid but leave the PURGE solenoid open. That creates a vacuum throughout the entire fuel storage system. Once the correct vacuum is reached, it closed the PURGE solenoid and waits to see if the vacuum holds. If it doesn, the system passes the test. If it detects a leak, it sets a code.
The computer also watches the electrical activity during the testing process. When the computer operates the solenoids, it sees a voltage drop on the line. If it doesn't see a voltage drop, it knows there's a problem with the electrical--either the wiring is broken, or the solenoid isn't working. In this partcular code P0446, the computer has detected an electrical problem with the VENT solenoid.
