Bus started making a deep clunk like a rod knock on route. Towed to shop, found broken flywheel. Replaced flywheel reinstalled tranny all seemed fine for about 500 yds. Tranny started slipping now will not engage any gear. Engine sounds fine, no whine from tranny, no check trans lite, no movement what so ever. I am kicking myself for not checking out the converter when I had it apart just got in a hurry, looking for suggestions, on what to look for when I take it back apart. 1999 444E coupled to Allison 545. All replies appreciated.

My guess is that converter wasn't clicked in all the way and it took out the front pump.

Is there a pressure check to verify pump operation while it is still on the bus?

you could simply loosen the spin on filter and check for pump flow, if nothing there then there is no reason to test further.

Why yes, the ORIGinal CHARGER is a Fastback

thanks for the replies, talked to a couple of techs from a transmission and they told me how to do a pressure check (small pipe plug just in front of modulator)had no pressure, as Bassman said, pump is probably fried, around a $1000.00 and more floor and creeper time.
