Should be 300 ohm's Can anyone give me the part #'s for the turbine sensor and internal wiring harness. Or where I can get these parts. I am going to pull the valve body down and replace these parts.

wolfe10 Report post Posted April 7, 2017 straycatboat, Welcome to the FMCA Forum. With your transmission serial number (on the driver's side of the transmission) you can go to or call any Allison dealer for the correct part. Where are you located? Share this post Link to post Share on other sites

wolfe10 Report post Posted April 7, 2017 At least a call to Allison could get you the correct PN. Then, if you find one for less $$ you could go that route. Share this post Link to post Share on other sites
