I just bought a 1989 240sx with the 2.4-litre SOHC KA24E engine and Automatic transmission. While driving the car if the rpms go over 5000 then it will not upshift. Has anybody heard of this happening and if so how can I fix it?
It will not upshift into any gear. If you step on the gas and the rpms get above 5000 then it will not shift into the next gear unless you let off the gas to get it under 5000 rpms then tap the gas and it will shift.
