How much does a lockup converter valve cost for a 85 mci 102a3.
If you install one the way Allison wants it you need 2 valves 1 is a bypass model it alone cost close to 400 bucks people get away with one from the rear governor port to test port for the converter. I have photos of how Allison does it on a 740 you really need the by pass valve it's purpose is to dump the oil back into the pan if the pressure is to high
could i see the photo pls that would help have u ever done one
