Slow Idle - Tranny Question

[86k10]

I was afraid you were going to say it was a foreign job. But in reality they all work with kind of the same principles. There is one good way to tell, but you will have to get some figures from a trans manual. If there are pressure taps to do it with, you need to check line presure and at the same time check what ever the other ports are whether reverse or 2nd or any other gears, to check for a leak in that particular circuit. But I would at least check line pressure at 450 and then 750 and compare them, that will at least show you if slow idle affects pressure. But make sure you have it warmed up to operating temp before you do this, for the most accurate readings.
