    Whining Noise in Rebuilt C4

    Yes checking like that it will turn both ways . In operation the centre is locked on the stator support and the actual stator then turns or is locked depending on load . What you're seeing is only the inner race The actual stator is on the outside of that inner race

    At this point , since issues are presenting in both forward & reverse , really need a pressure gauge on there now see what is going on. Shame you're so far away i'd take a look at it It's got a ton of oil in it . Usually a deep pan and smaller converter is around 8-8.5 litres

    Only in forward ? Reverse ok ? Does it feel like a slip ? What converter was fitted ? The sealing rings on the pump? Fitted back right? Were a snug fit in the grooves ? As there are two widths , early and late , or you use the same stator support and just swap pump?

    XD Tacho wiring

    Have seen them run with coil wires reversed

    As you say . Nothing really obvious there . Bush looks fine . Clearance is a bit tight and a bit more would be preferable but I don't think that would be the noise . Gears are new and outer good looks correct , dot was downwards . Bush is fitted correct with respect to the lube notch Only other thing , I have heard about it but never had it happen myself is the converter making a noise

    The converter is normally guided in the pump bush and the pilot or spigot in the motor . That should keep it centered. But as I mentioned that mark where the bush has been running if it for some reason has picked up or is not central could put the inner gear into the crescent. Also need to verify that there was in fact correct clearance . That can be measured with it all apart , get a reading blockplate to flexplate ( usually around 19mm) , then seat converter in trans and get a reading bell front face to converter feet )Usually 23-24mm). Perhaps the no push back was just where was caught in the mount holes . A little tidying up in those holes so they fit easy will help going back together

    AU Transmission Job

    Just to clarify a bit , up to AU internal wiring is grounded inside the transmission . From BA on , the internal harness is different and the grounds to all solenoids go back to the ECU , so they are a no go. There is also a variation in AU I came across . Although the internal harness looked the same the plastic plug into the case was a different size/diameter than the earlier models . Not really an issue . I only came across it as a mate built one , wanted to use the late case , then found his earlier case from a V8 EB or ED or whatever it was different where the harness fitted . Luckily I had an AU harness worked

    That last pic , assuming converter was reco or cleaned on rebuild ? shows signs of something going on with the front bush , if it has picked up or damaged the bush could contribute to a noise Rest looks fairly normal. Bit odd the studs are catching in the flexplate

    You can do it . Best would be to stand it on end , output shaft down, pump upwards . To make sure nothing does come out of place , loosen front band lock nut , screw adjuster in till it's firm . That will prevent the clutch drums lifting up as the pump comes out . Then bellhousing off , unbolt the 7 pump bolts . Just make sure that there's not a little screw also , some occasionally have a small phillips head screw as well as the 7 9/16 head bolts Pump should lift up & out easy enough since it's not that old

    The pump gears. Inner gear, the bevel on the gear must face forward. The outer gear if original will have a dot must face out . If ar=aftermarket gears, then outer gear usually can go either way . the outer gear has a bevel on the inner teeth is the reference point Also needto look at the crescent in the pump , see if inner gear is wearing on it

    That's not good . Should slip back easy 3-5 mm . Starter won't have any effect. At this stage likely the best next step is remove trans , do some measuring of converter etc . Then pump out to inspect . I'm wondering if inner pump gear is fitted backwards could cause all these issues If old mate that built it left that valve out at the filter who knows what else he has f___ked up

    With that valve missing , the guy clearly has no idea what he is doing. What else was done to valvebody? Makes me want to question if pressure reg valve is fitted right or what else he might of F___ked up

    Oh now that valve missing is a hug issue. How the hell did someone rebuild and leave that out? Just WOW !!!!! With that missing it's a wonder it's not slipping. As to oil level , be sure to verify the stick is correct. Run sting alongside tube and see where the "full" level is exactly

    Really need to look at the pump first . Since it was noisy previous the clearances in the pump and crescent "should" of been checked. It "should" of had new pump bush fitted. if there is contact with the crescent to inner gear there is a mod you can do Was converter split open or replaced during the rebuild? If it was then comes back to pump. If it wasn't then it possibly could be converter
