Took a trip to bunnings to make a super special tool.
Bought some 150mm PVC pipe.
So the next step would have been to measure the clearance from the pump mating surface to the bearing surface you can see in the last pic.
However I'm now having one of those "might as well just do it while it's apart" moments. As long as I can get one to suit my converter that I've only recently bought, I think I'm going to go with a 1-piece input shaft instead of the two - even though my current inner shaft is 300M material. My current converter is already non lock-up, so going to single shaft will make no difference except that it will be a lot stronger.
Didn't realised I hadn't updated this in a while.
So in the end, none of the one piece setups could use the stock converter splines.
I was still of the opinion that I'm building this box with all the 4R parts to make it as strong as possible, so why stick with a known limited input shaft setup?
So I bought the transgo one piece shaft kit. It replaces both the input shafts.
The reason there hasn't been an update in a while is because as per the picture above, a bush needs to be pressed into the AOD stator to support the single shaft, unless you have a specially built AOD/C6 hybrid converter that has built-in support. Since I was using a standard config C6 converter (3000rpm stall), I needed the bush.
Anyway, TRANSGO's "Detailed Instructions included with torque converter and flywheel types and choices. Ease of installation!" (direct from their website) were apparently not so detailed. Their instructions say to make sure the stator is clean and press in the bearing.
The results are as follows:
In case the pic isn't clear, the stator cracked as I was pressing in the bush. When I measure the bush vs the stator, there was 20thou interference. Way too much.
I called transgo and they were zero help. Lesson learned - trust nobody, measure yourself.
Anyway, I brought a new stator in from the states and had another crack at it. All good this time. "Finished" the box yesterday.
I say finished because on the day I do the box swap, I need to steal the overdrive servo (oversized), shift linktage, tail housing, valve body, and pressure transducers from my old box.
