Any tips welcome - I just removed the old transmission and ready to install new;

Yesterday I mounted the gearbox by myself and it is a hell of job to do it without help; I first installed the torque converter and lined it up with the pump teeth to the best of my ability; then the gearbox went in quite easily however, the last 6-7mm I pulled together by screwing the bell house bolts - it did make IMG_3130.jpga pop sound at this stage and then went in all the way without any difficulty; I am a bit worried about the “pop”; could I have broken the teeth or did they just slipped in the converter slots? I asked Dave Ashcroft who did my transmission and he suggested to take the gearbox out and inspect the pump teeth; that is quite a thing to do again by myself.
Does anyone have a suggestion as what damage I could have done and if breaking the teeth would jam the gearbox or would still allow it to come easily together? I am looking for reasons not to take it out again but I have a feel that I will have to anyway.
your thoughts are welcome

The rear axle is now complete, I only need to add oil; I had two issues - the 2.5” lift springs seem to be too short and I had to install dislocation cones and the sway bar disconnect are too long and I wonder if need to install bigger bump stops

I don't have an answer, but the torque converter sounds like it wasn't fitted all the way down. It doesn't just slide on and then you're done, it drops down twice if I remember correctly. If it hasn't seated all the way down and you do it up on the bolts when fitting the transmission then it will break the pump. I'd be doing as Dave said.

Thx for advice. That could have already happened and it is good to check it now. In hindsight one would mount the converter to the the gearbox and install it together?

Agreed. The best case scenario here would be no drive. I feel your pain, they are a pig to do on your own, and at my age I doubt I could do it again.

That is the only way, really. You will find that access to the bolts is a right **** though. You will need a long, slim spanner and a large swear tin.
