All the above is the reason I dont touch bloody trans
if its trans related off to the shop,then bend over and take one for the team
OP also has impatient tendencies from his posting style.
When I put something together and everything doesn't work as I want, sometimes tearing it all down and methodically doing it again is the best strategy. Now with smartphones in our pockets I love to take pictures of everything before after and during as well.
I know that's a little late now as it's been pulled down and put back together a few times but spending the time to get it right always gets the best results.
Knowing your limits is also a good one, i had a rear main go and yeah that was above my pay grade so off to the shop it went, felt that one burn on the way in!
