Hi guys, I'm planning to change the tranny fluid on my '94 E320. What is the best way to align the the torque converter drain plug to the hole in the bell housing? Can the alignment be made without removing the fan shroud? And, the idle on the car in park sometimes rises up to 1000-1200 rpm (engine warm to operating temp), when I gun the gas pedal, the idle drops slowly back down to normal (about 650 rpm). Throttle positioner sticking?, where is the thing? Thanks......

 

Use a socket on the front of the Motor. The crank pully has a (forget mm) bolt. I used it to turn the motor and my arms are not that long so it should work fine. Its a pretty easy job, I don't know why all car makes can't think about drain plugs for this.

There's any number of ways to accomplish this. A 27mm socket with the proper-size extension (it has to be just right) will turn the engine. Turn it clockwise only. It may be helpful to prop a mirror under the transmission to see when the plug presents itself.

Some others walk the flywheel by prying on the flywheel teeth.

 

To use the 27mm socket I assume the fan shroud needs to be removed for clearance? Also any suggestions on the idle problem, I noticed that when I stop for a red light , sometimes the idle goes up in drive too? What should I look for? Thanks.....!

 

If you have a buddy, and a good set of jack stands, get under the car after properly secruing the jack stand and look through the window in the bell housing where the drain plug will be. Get your buddy to bump the starter while you watch until the drain plug is visible through the window. Shouldn't take more than a couple of tries. I don't have to tell you that getting under the car requires safety precautions that must be adhered to. Use jack stands, not the spare tire jack or a block of wood.
