my goofy 240sx

[yangs13]

for some odd reason, my 240 has been weird symptoms: idle fluctuates from 500 to 1200 rpm, gears shift really hard in 1st and 2nd. when i let off the gas, it seems to be stuck in a gear so it seems like its in neutral-revs drop to 700ish rpm. a grinding noise has appeared when in reverse. its an automatic. im assuming i need a transmission flush, but the idle problem is perplexing...

sounds like a transmission problem

don't recromend a flush

going to need a new transmission soon... really wierd it has a grinding sound going into reverse.... your completely stopped when you go into reverse?

your transmission should have a drain plug on the bottom of the pan, just take that out and when its done draining put it back and fill with new fluid

mercon/dexron III is what you want, and you will need 3-4 quarts if you don't have any leaks...

check fluid level in Park, after refilling, start car, put gear selector in each position for 3 seconds going from P-R-N-D-2-L-2-D-N-R-P and leave car running, take out dipstick, whipe clean, re insert, take out and notice fluid level... add in 1/4 quart amounts as nessecary... and if its not on the stick at all add another quart and continue the process....

5 speed swap ftw.... autos suck unless your making a drag car, then some ppl still like stick better.

i am at a full stop when i reverse, its usually backing out of my driveway. ill change the fluid and see what happens from there
