Will this part I ordered from you bring my idle back down to normal?

I have more questions
As far as your idle, Your IAC valve and coolant sensor will have much to do with that. Also check for vacuum leaks. You first need to check for codes and repair what you know is bad. The shift solenoids control your shifts but they also get input from your TPS sensor so I would also check to make sure your TPS sensor is good and adjusted properly. What are your symptoms? What are your codes? Thank you for your excellent feedback. Thank you for using just answer. You can continue asking more questions here

Wrong part wrong Youtube wrong transmission. I am sending the part back. I drop my oil pan and it was totally different from the video.

That part is for the trans that came with your vehicle and fits 94-99. If your trans has been replaced with something else I have no way of knowing. I will opt out and let other experts see if they can help you.

my trans is original form new. that part you sold me is now where to found. the youtube i was looking at is not my trans. I pulled the pan off look nothing look youtube. 1994 318 B250 van

Are you saying there are no wires and no solenoids inside your trans? they made two different types of control solenoids, one with converter lock up and one without. See this link:,carcode,1073854,parttype,8476,a,


Are there any other codes? Have you replaced the TPS sensor and checked IAC valve? Have you checked your coolant sensor? These sensors would affect your idle.

Where is it located it is nothing like the YouTube you have. I will look for some numbers tomorrow.

Here's a couple videos but they are lengthy and completely go through the transmission for rebuild. The solenoid is located on the valve body.

I would take a close look at your coolant sensor for idle problem.
