Today i was playing around with my 240sx, (practicing how to drift)... when i was done, the car seemed fine but a slite slow now.... I have a 93 240 automatic with over drive...... i left the parking lot and floored the gas but the car didnt take off like normal so i did a few test while driveing.... Conclusion-----I droped it in first and it was fine,, then i put it in second and it was normal,, but then i put in drive and nothing happend.... it was still running in second. i know it has to be the transmission but i am new to the sports car world and my 240sx is my pride and joy.
Some one please help me with this on infomation so i have a good idea on what to look for.
P.S. i just joind this forum yesterday, and this happens to day. coincidence or what!!!:help
Automatic transmission problems!!
problem just gone!!
Ok.. I hade a prob, with my trans two days ago, and well.It just dissaperd like that the next day. The car is fine now!!!! This is not the first time my 240 has pulled a hudiny on me.I have read in other forums about missfireing problems that just dissaper like that.. My car has done this too, twice in two months! Is it possible that the O2 sencer could cause slugesh response without the missfireing, therfore (thinking) it was a tran's problem???
I have not replaced the O2 sencer yet, but plan to here very soon.

Re: problem just gone!! (chino)
Yeah, that same thing happen to me. Almost exactly... playing around in a parking lot, jammed the gas to go... no more torque, uh oh, drove home trying to diagnose. I left it in the garage overnight (unpluged the battery to be sure) and hopefully in the morning it'll go away.

same problem, but maybe an answer
I had the same problem in my 96 240... jumping into my 240 after work in an empty parking lot, I started it up, let it warm for a minute, then spun the steering wheel left, stabbed the gas and let her rip from a dead stop for a couple hard counter clockwise donuts then ripped the e-brake to stop.The trans was not hot, it was three minutes warm from sitting 10 hours at 40 degrees in the rain. Over heating is not the cause.Same symptoms as I nursed the car home.. slipping, not shifting properly, no overdrive nothing, just stuck in 2 to move the car.Next day... NOT A DAMN THING WRONG... or for the last two weeks of normal driving. I'm not ready to throw it around again in case my theory is BS...... After reading about the trans a little in the tech forum, here's mysemi-educated theory:since the trans pressure is constantly monitored by the computer, if the pressure drops suddenly.... as in, IF the trans fluid flow is interupted or starved for just long enough, it will trigger the trans into safe mode...
throwing the car counter clockwise then coming to an abrupt halt will throw the fluid around enough AWAY from the pickup that it starves the line, the computer says PROBLEM and triggers the safe mode.
by shutting the car down, the computer resets for the next start up. At next start up, the fluid is settled and pumping at normal pressure, the computer says everythig is OK and away we go.
I also believe it has to do with counter clockwise donuts and coming to an skidding halt out of the donut instead of driving out of it. I've had my 240 since 36k, now it has 154k... together we have logged butt loads of slideways miles in snow rain, whatever, and this is the first time for the trans problem that just went away the next day... I need to check my trans fluid level.. that might be contributing to starvation.. duh..
