I am needing to replace my Transmission Output Speed Sensor on my 1999 Dodge Ram 1500. I have watched a YouTube video on this replacement, and they used a transmission removed and placed on a workbench. My question is this; I am wanting to do this replacement with the transmission on the truck, and I was wondering if transmission fluid will rush out when I remove the old speed sensor? The video I watched had the tranny on a workbench, with the sensor out and there was only a few drops of fluid on the bench. I am assuming that the fluid had been removed from the transmission I saw on the workbench. Please advise, and Many Thanks, my name is Warren.

It will be the same just a little more dirt you won't loose much fluid at all.

By the way I just wanted you to know when I replaced the output sensor on my transmission today on my Dodge Ram, transmission fluid did come pouring out all over me and my garage floor, so you were not correct in saying not much would come out. It was a lot of fluid coming out.

We can't be perfect even if you expect us to. On a hoist that doesn't happen because car is level.

My friend I was not trying to be mean, I just wanted you to know that if you do it in your garage at home, the fluid really pours out. I got covered in fluid. I don't expect anyone to be perfect and I thank you for your trying to help me, my check engine light is still on after replacing the trans speed sensor. The electrical connection to the sensor got covered in fluid and I wiped it off as good as I could but the check engine light is still on, I thought I might replace the rear sensor above the gearbox, What would you advise? Again, I did not want to offend you in any way, your help is appreciated, thanks.

Clean connector with either brake clean or choke cleaner then use dielectric grease on the connection. Then drive it and rescan for codes to see if it's the same one. Give us the code so we can investigate this further as a lot of times replacing a sensor doesn' t fix it due to another problem. Do this before you spend anymore money

Wow, I live in Henderson! I live by the Henderson Auto Mall at the junction of the 95 and 215 Fwys. All in fun, you should have seen all the fluid coming out, if I was watching someone else and the same thing happened, I would have busted out laughing! Even if it remedies the problem, doesn't it take a little while for the light to finally go out, it doesn't go out(check engine light) right away?
