A833 assembly tricks

No problem, it only take 20 minutes or so to drop the trans and another 5 to split the box open. So changing it later is only a couple of hours work,including getting the car up high enough to work under....... lol.

I get it ;) Although I have a lift this isn't something I want to do several times. Would it help to leak test the transmission on the bench? Fill it with warm/hot oil and see if it leaks from the shaft?
Or does it work to remove the reverse shaft if you turn the tail housing around (like you do when installing the counter shaft pin)?

BTW
I use 50/50 Dextron-III / 80-90 gearoil. The only reason gearoil is in there at all, is for longevity of the highly-loaded and fastest-wearing part, the cluster-pin, and for the pilot on the front of the M/S.
I tried full-synthetic but couldn't make it work at 6000 to 7000 rpm; it was just too slippery, slowing the shifts down. I really really tried.

noted!
