Perfect fit on my 1993 F-150 with the inline 6, no issues whatsoever. Kept having a check engine light for a while and took it to a shop and I was told it was the range selector and cpu. I changed the range selector which made a huge difference in shifting. Turned out the sensor was the actual culprit. Stopped the slight hesitation and the light is now off. Quick and painless install.

Temp gauge stopped working, and my truck was running rough. Put new one on runs great again.
