You want this one...

Al, The tech at Summit read off the specs on both and only the 8998 will test the shift light pattern, which is what i need. So it is on the way At $392 I hope it covers my issue! I did test the throttle stop/ transvrake sequence several times without a hicup. No issues, and plenty of clearance around the components. So i suspect it was due to the wrong shoes and my big feet,! rest assured, this lesson will not be forgotten.


My 89981 works the shifter just fine triggered the same way but with a grid. The older testers will NOT work with a grid. BUt I have one of those in the trailer as well still.
