To the point: I just got a '93 Maxima GXE used at an auction, so I wasn't able to take it on the highway or anything. The instrument panel acts wacky (the wackiness being that the temp gauge fluctuates, usually higher, depending on what electrical thing is activated, there is no tachometer response whatsoever, and the speedometer is off by seemingly random amounts), the radiator fans run all the time, and it only uses 1 forward gear and reverse. Oh, the horn doesn't work, either.
The tranny fluid doesn't smell burnt and is pink, but I'm a little confused when the stick says Dexron. I thought I'd see something to indicate Nissanmatic. Maybe I'm just a tard.
Also, for what it's worth, it's hard to tell how high the engine revs by ear because there's a super-quiet aftermarket exhaust on it.
I'm thinking that I'll have to hunt down a bad ground somewhere to solve the instrument problem, or maybe at least replace the temperature sensor. After doing a little hunting around, I seem to think that the ECU is the most likely culprit for the transmission problem. Either that, or one or more of a dozen or so problems.
Everything else seems to work OK; lights, wipers, brakes, no leaking fluids, no funny-smelling or funny-colored exhaust, and none of the idiot lights come on. Which brings to mind a question: Will the check engine light come on if the ECU goes bad?
Also, if the wrong tranny fluid is in it, will the tranny go into failsafe or will it just ruin it?
Sorry for the long post, but I've come to realize that as much info as soon as possible is a good idea in most cases.
edit: also, sorry for interrupting the previous guy

holy crap how much did you pay for it? not much, I hope!!!
lemme read the rest of the new posts and i'll get back to you..
edit: ok.
even tho the CEL is not on, you may still have stored codes (ie, my 02 sensor harness had broken wires but still no CEL... but i pulled codes and it revealed a 33, i traced wires, fixed the broken wire, MPGs went from 15 to 20 overnight. gen maintenance sticky post #18 tells you how to do that.
tranny... hmm, i know there's a way to do tranny diagnostics too. i think your speedometer/tachometer issues MIGHT have a hand in this. some of those problems will throw codes at you too, so checking the ECU code may tell you if the CAS is bad, if the ECT sensor is bad, etc. also does the odometer work properly (following milemarkers on the highway)?
tranny fluid is dextron2 or 3
as for some of the cluster issues you may need to just get a new cluster altogether.... but not until some of the other tests are out of the way
