I think somethings wrong with my automatic...
Well this started last night while I was doing the local "bogan laps".
the trans shifts and everything, but the shift themselves are very very harsh. ie, 1st > 2nd is really bad while the rest get better. not so bad while under hard acceleration but dam, under light throttle its like the trans wants to split apart or something. This startted suddenly and I have no Idea what it is. I wasnt driving hard or doing anything I shouldant have been doing. I cant get to a dealer for a few days, but need to dive the car, will it damage the trans? (im thinking yes)

The Throttle Position Sensor detects the throttle valve position and sends a signal to the Engine Control Module.
The Throttle Position Switch consists of a Wide Open Throttle position switch and a Closed Throttle position switch. The WOT switch sends a signal when the throttle is open at least 1/2 of the WOT position. The CT switch sends a signal when the throttle is fully closed.
The Sensor and Switch are integrated into one unit designated TPS. It is mounted on the rear face of the Throttle Body, in a reasonably accessible location. Procedures for testing, adjusting, and replacing the TPS appear in the Chilton repair manual (page 4-18) and the Haynes repair manual (page 6-8). These procedures require only an ohmmeter and a screwdriver.

This test is made with the ignition off. Disconnect the connector and use an ohmmeter to measure the resistance. It should be about 12 ohms.

1) Minimize the number of miles driven until repairs can be made.
2) Find a friend who drives a 4Gen Maxima and measure his dropping resistor for purposes of comparison. If he is willing, borrow his dropping resistor for a five-minute test drive. This experiment will reveal if the resistor is the cause, and the only cause, of your symptom.

You may just head on down to Radio Shack and pick up a resistor around 12 ohms or so, and I'd assume around 5Watts. Just put it in place for the time being and your trans should shift better. Actually come to think of it, if you just went up a little in resistance, perhaps thats a good mod in making the slushey auto shift just a bit harder??? IDEA ! ! ! !

Before checking the electronics, have you checked your ATF level recently?? You will be surprised how low ATF level will affect your shift quality. Make sure you don't have too much ATF in there as well.
The Maxima uses Dextron III ATF.

Would I be right or wrong?
Maybe a dial mounter in the cabin, or even better, how bout a factory nissan switch for dimming the dash lights wired properly to do this instead?
Just some Ideas...

Ben Garner tried a variable resistor... and it burst into flame! He then realized that he needed a high-power "pot" to make it work but decided the switch suited his purposes well enough.
