I know they usually break off when removing old one, my question is how to get enough room to remove 10mm bolt holding clip and pull old sensor out? Chevrolet and others say if it breaks off, tranny has to be dropped to remove the part. I've already sprayed half can of p-oil, let set overnite, wondering if anybody has experience in actually getting enough room to get your hand in there to work?

 

I got an 8.1 in my 1500 and I have changed mine in the vehicle. granted it aint fun. I did mine from underneath. twisting it helps a bunch

 

yep same thing here! underneath is the only way I know how...and its miserable! Just a bad location. But I didnt break mine when I took the old one out
