Th400 users? Where did you mount your tranny temp sender? Where is the best place to put it without worring about any clearence issues? Probally a no brainer question just curious if anyone has had problems with where they put it.

I put it in my passenger side of the oil pan. Use a insulated thermocouple wire and just run it up the tranny and through the firewall by the PCM somewhere.
As far as the speedo goes, the sprocket gets pressed onto the shaft inside the tail section. Then the sending unit is bolted into the side of the tranny. Then get the connector and splice it into the speedo wire from your factory harness. No polarity, just hook it up. Then you need to recalibrate your VSS pulse rate by increasing your tire diameter. My car thinks that it's on 57" tall tires to get the ratio pretty close to correct. That's for six speed conversions. A4 Conversions use a different pulse rate that you need to adjust to. Best way is to keep adjusting it using a fixed RPM in 3rd gear to obtain your MPH. Continue to adjust until they match the calculated MPH. Or get an officer to clock you a couple times. Sometimes that works, depending on how cool your local police are.

I mounted mine in the same place as Derty. I have an Autometer Pro-Comp tranny temp gauge installed in a dual pod. As far as speedo goes......well, it's on my list after I have the tranny freshened up in at the end of the upcoming season.
Oh, your a funny guy. Go blow up another new engine Jim. 
Its gotten a few break in miles. Its only been away from the dragstrip for 2 years....so its gonna get thrashed this year.

The location is on the transmission housing by the tail shaft. Looking at the transmission from the rear it should be at the 10 o'clock position. You won't be able to just plug it in. The exciter ring needs to be installed in there. Also, it might be possible that your housing doesn't have the location in it for the sensor.
