Last night I pulled apart my AW4 to determine why it was not generating oil pressure...turns out the gear inside the oil pump assy had shattered into about 7 pieces. Rather than replace the gear and take my chances, I'm looking for a good complete used oil pump assy. Not sure if it matters but...

It does, a great deal. Thanks for the detailed response. Knowing the converter is directly coupled to the flex plate and the trans oil pump, the issue I have with no pressure being generated is most likely due to a bad or damaged pump. Only thing left to do is remove it and tear it open to...

TTT - Still looking for advice and a response to my TC operation questions Chris

Not entirely true...I swapped in a 96HO XJ motor into a YJ using an 87 XJ Harness. I used the HO intake manifold and had a machine shop mill me an aluminum throttle body adapter so I can use the 87 throttle body on the 96 intake. Chris

Maybe you can explain to me how the convertor operates in an AW4 and how it would effect the hydralic pressure? I thought that the two knotches on the convertor lock into the pump - and if that's the case it should still be generating internal pressure as I verified it was attached to the...

Here's the low-down... 87 AW4/NP231 combo behind 4.0L swapped into Jeep Wrangler. Everything was kosher until 6mths ago when the rear driveshaft blew a u-joint at 70mph! Twisted the rear driveshaft, shattered the NP231 cone (was slip yoke style). Swapped in used cone and rebuild a driveshaft...
