i have been thinking and searching alot. but stil have a couple questions. i want to hook up a trans temp guage because i want to take as much percautions as possible with my new diff and tranny. what size sending unit do i need because i heard there is a spot on the top of my tranny that i can thread the sending unit in without modification like drilling. its a 95 mtx. any links to a kit they have used? i would prefer the gauge be blue led.
