no drive on new automatic gearbox box - Hamsafar
I have had a small garage fit a new GM 4L30E (recon) automatic gearbox to my Omega, but there is now no drive.
I got the gearbox from a working low mileage late model, and then replaced lots of seals in it, some I did myself, and some an automatic specialist did. It has then been in dry storage for 6 months.
We are wondering if it was because I emptied the fluid out of the torque convertor before, will this cause the problem, by there being no fluid being pumped, or should it fill when the fluid is put in?

Does the torque converter pump the fluid round or a seperate pump.

We have filled it to the level drain hole with the engine running etc...

Thanks for any advice.

Possibly the secondary pump is bone dry and will not prime. A sectional diagram of the box might give a clue as to how to achieve this (?priming plug), if there is no documented procedure.

Thanks, yes, it was all bone dry inside apart from a protective film.
I replaced the main pump seals and gaskets as a precaution.
The diagrams I have aren't very detailed, but I can see the pump. Maybe we need to overfill it via the top vent pipe so that fluid fills everything?
Or maybe somehow pump fluid into the rubber hoses to the cooler.
Nothing's ever straight forward.

If the torque converter is bone dry, will the pumps be rotating, or will just the donut part of the TC be spinning and not transfering drive to the inside part, and thus the splined shaft and gearbox/pumps?
