I was wondering where on the transmission do install the sender for the temp. gauge. My truck has a auto with O/D I believe its a 46rh.

 

The best place is to put it in the hot line with a thermal T.



That's supposed to be more responsive and accurate than in the pan. I don't think it makes as much of a difference as a pre- or post- turbo pyrometer, but I'd think it has to be better.

 

Now should my tranny have pressure test ports, I was told the 47rh did and the company I am getting the gauges from said thats where they put there sender for the trans temp and I was wondering if my tranny was the same way, but I havent had a chance to get under my truck latly to see if does
