1. After stopping a a stop sign, the car acted like it was in neutral when I tried to go (shift lever was in Drive). Finally I was able to go. It has done this twice now, in approx a week. Rest of the time it seems ok. Car only has 47k miles.
2. Looked under the hood, trans fluid is at the normal level. No leaks seen under car.I did notice a vertical hose coming from the transmission hooked to nothing. First I thought maybe it had come loose from an engine vacuum source, but found no "open" vacuum fitting on the engiine. Therefore I am thinking that this hose is a transmission air vent, although it seems strange that the end of the hose is open to the engine compartment at its upper end, (If its an air vent seems to me it should have some type of small breather or something).
Any ideas/info on #1 ar #2 above would be helpful.
I would suggest having the fault codes read and check for a problem torque converter clutch servo/ solenoid problem
could be a bad connection but from your description that will be the area of concern
SOURCE: My 1992 Nissan Stanza has transmission leak.
The stop leak treatment may help the seals to seal better but I would get the car to a good transmission shop since it has that many miles on it. The fluid probably needs flushed out and changed by this time.

That is alot of work. It would **** to have a mechanic paid to do this but unless you are pretty good with a wrench and have a hoist and such then it wouldnt be worth your time. Normally what is required for something like this is supporting the vehicle on jack stands and removing both front tires. Once front tires are removed you would then have to remove the axles which includes the brakes/rotors and what not. Once the axles where removed you would unbolt the transmission and remove it. Now the problem is if the engine is supported by a mount that bolts to the transmission you are going to have to support the motor with a hoist or jack until the transmission is installed. All in all it isnt really alot of work if you know what you are getting yourself into and have all the stuff you are going to need ie jacks/hoists/plenty of tools and a good weekend. Also remember all the small stuff that might need to be unbolted to clear the transmission

With the ac, sounds like you definitely have a short with the ac electrical wires. Have a mechanic check that out. 2. The wiring for the dashboard gauges may have tears or something is causing high resistance in them or you may need a new dashboard itself. Have that checked too.
As far as the brakes when you trying to change gears, what do you mean brake lock wont open? Finally with the RPM, I dont think your dashboard gauge is working correctly so you may need that replaced also.
SOURCE: No "connection" between engine & trans?
check your driveshaft from the trans to wheel (both L and R). Possibly it popped out or is disconnected.
SOURCE: 2001 Nissan Altima - Instrument panels gauges stop working
My 2001 Altima's instrument gauges die out after high-speed driving for 40-50 miles. Engen also loses power. Everything is back to normal when the car cools down. It turned out the ingition relay was bad. I could duplicate the problem right away by removing the relay. Actually, it is very easy to find the relay which is located above the fuse panel. The ignition relay is the bottom left one among the five relays there. It costs only $20.
