Hi Jay, none of them are really 'mandatory' per say, however the use of a test plate allows you to air check the entire assembled case, affording you one last opportunity to catch any potential problems with the apply circuits before it goes out the door and/or back into the vehicle. I like it for the TH350s because you have two out of three apply circuits bounded by sealing rings on the pump, which can potentially break on installation if either you're not careful or one of the sealing rings just happens to get caught up somewhere and you don't realize that it broke due to the weight of the pump or noise in the shop, etc....It also allows you to air check the intermediate clutch and assess clutch clearance via the large circular cut-out a lot easier than trying to use just an air nozzle in the worm tracks.
You don't really need it..Just take your air nozzle, put a one-two inch vacuum hose with a blow-tip on the end and use that to test the forward, intermediate and direct clutch circuits through the case once it's fully assembled but before you put anything on the belly of the case.

2 years later and this helped a lot with replacing the accumulator seals on my Turbo 350 thank you so much man 👍🏻
Awesome, man. Glad those videos were able to help you with your TH350...Thank you for watching, Angel!
Excellent explanation with good lighting. A great helpful video, thanks a lot!
Thank you, Thomas! Appreciate the kind words.
Best, most thorough th-350 tutorial I've ever encountered, thank you for doing such a great job!
Thanks for the kind words, man - appreciate it!
Looks like you could pinch around on the o rings and make them pucker and that would let you get your pick in to get it out
Is it mandatory to have the plate for testing? I want to air check my build but would not be able to source anything like that.

What kind of lub do you use
Lubeguard "Dr Tranny" Assembly Goo (blue for general purpose, green for holding/retaining check balls, bearings, etc)
@@nickstransmissions Yep, was gonna ask that one as well.
eBay test plate $170 bucks :(
