1999 Intrepid 3.2L Transmission Speed Sensor

I just ordered Mopar Parts # 4800879 (Output) and 4800878 (Input). Based on posts here (thanks Bill and others), it looks like I will need a 1" deep socket. (That will be the first non-metric tool I've ever used on the car :)

You're welcome, Greg.

You might find that an open end wrench from below or from the side will work better on one sensor or the other depending on what other stuff (harnesses, pipes, etc.) may be partly in the way of a direct shot with an extrension and socket.

Jack the left front up (use jack stands of course), and access from lying on the ground. The sensor bodies are plastic, so just lightly snug them up - an o-ring seals them to the tranny case (i.e., sealing is not dependent on torque).

Sounds good. Did any fluid come out when you removed the old sensor? My driveway is sloped so I'll probably limp to a shop where I can raise the car and work on it.

No - none at all.

One more question, do you remember if OEM sensors have any markings on them identifying them as Chrysler parts? I purchased two sensors which are allegedly Mopar parts but they don't have any markings or numbers on them. Most OEM parts that I've seen have at least the Chrysler symbol and usually the actual part number. At least it doesn't say "Made in China." :)

Of course maybe it is better if they *aren't* the Chrysler parts, but that's another issue :)

Not sure, Greg. When I've bought them from the dealer, they are in sealed plastic bags with the part numbers, etc. on the *bag*. I don't recall if the sensors themselves had part numbers on them.

As far as OEM vs. aftermarket being better, it's anybody's guess on a given part. Many parts these days come from the same manufacturer whether going into the OEM or aftermarket system (but then again, sometimes parts that are slightly outside the OEM spec. on the production line often get shuttled over to the aftermarket suppliers). It may also be that both aftermarket and OEM replacements have been redesigned so as not to fail as often. I wouldn't lose sleep over it. :)
