I've a WJ 3.1 TD Diesel (sold in UK & Ire.) it has the 44RE I though I post here as I believe 44RE was fitted in the V8 ZJ.
metal fast clinking noise coming from transmission when the revs reach 1400 revs and goes away before revs reach 1500 in park neutral and in drive. (slightly lower rev when driving)
Thought it might be the exhaust hitting somewhere as it does sound very much like it's vibrating of off body part. Crawling under the jeep I inspected then poked and pried the exhaust but it doesn't seem to be hitting anywhere. But the sound seems to be loudest at transmission bell housing
where it bolts to the engine.
less noise at oil sump so I suspect flex-plate or torque converter bolts but I don't know.
Any suggestions greatly welcome.
