Hello sirs,

My Amigo has the GM 4L30E auto transmission in it. I'm having some occasional symptoms that tell me that the Range Mode Sensor is dirty and needs cleaned. Apparently it is only an approximately 1 hour job, but I'm afraid to do it myself. I don't want to pay a shop to do it though. Anyone here have any experience with this transmission and be willing to walk me through this?

I could bring your beer or some cash. This is our ONLY vehicle, and I drive A LOT though, so you have to promise me that we won't screw anything up. I literally can not afford any down time.

If you know how to change the diff oil and drop the tranny pan and change that oil, I'd be down for that as well. I've worked on cars before, but never really owned an automatic transmission, or a 4WD before.

Please let me know. I'm available Wednesdays and Fridays between 10 am and 3:30pm and Saturdays until about 4 pm.
