Question about Hyundai Elantra
Rough idle,and when i shift to reverse or drive the engine more rough,i change the coil pack and transmission speed sensor but still the problem excess
Would search first inlet air leak in between air box and engine - all hoses on, clamps tight no cracks
then disconnect idler control - about where the engine accelerate cable comes in / most probably opposite. Problem still there?
look for ignition - plugs, check leads with multimeter, connections

It's definitely cheaper to buy a trans from a wrecking yard than to have yours rebuilt. Before you do anything though. Did you make sure that the trans fluid level is full? I know this may be a stupid question, but I had to ask. The speed sensors job is to tell the speedometer how fast you're going...not related to your problem.

I had the same problem with my 96 Chevy 4.3. It idled rough enough to shake the truck at a stop. It revved up fine but sputtered on take off. My truck did not want to stay in overdrive because of the low rev. I changed cap, rotor, plugs, wires and this did nothing. Finally I took the intake off and found corrosion on the side intake gaskets near the rear of the engine causing a vacuum leak.

SOURCE: Volvo S60 sensor ?
Sounds like an oxygen sensor (there are two). I had a recent problem where I had a rough idle and my S60 continued to stall out. Turned out to be the rear oxygen sensor. After replacement, car idles nicely and car drives normally.
