I have been doing bench time on transmissions for 4 decades . This is quality content ! Seen how clean the inside of the bell housing is ? A sign of quality right there .
I have th350 where it had three frictions in the direct drum. I had the apply piston machined down to accommodate 5 frictions, but the clutch clearance is now showing .027. Wondering if I'll be ok or if I should pursue having it machined down again to obtain .050 clearance? Appreciate your thoughts.
You need a bare minimum of .040” and .050” is ideal; .027 is way too tight for a five-clutch direct drum stack up. Are you running stock steel plates or oversized (.090” thick)? If you have enough meat left on the piston to further trim it down. If not, see about machining the pressure plate down a little to get the clearance you need.
@@nickstransmissions I'm running stock plates. I rechecked the clearance and it's at .040" but still went back to the machine shop to see if they can shave .010" off. Really appreciate you confirming the clearance! I'm also wondering about the plastic retainer piece at the very bottom of the stator shaft of the front pump. I can't seem to find a replacement for it. I've called around and all they have or show in their system are the 5 sealing rings for the front pump. The pump I have does have 5 sealing rings but at the very base of the shaft, there is a thick plastic ring with a slit in it so 6 rings in total on the shaft. It looks like it holds the thrust bearing in place?? I wanted to replace it with a new one since it's like 50 years old. Any idea?
Hi Pernell, if you're referring to the sun gear-center support thrust washer, then it will impact stack height if you delete or forget to install it. It's not selectable so the original or an over-the-counter (or good used) replacement will work.
Hi, yes - just remove everything from the case belly (valve body, spacer plate, reverse hold-down/support plate or aux VB if a TH350C) and put shop air into the low reverse feed port at the back of the case. I show this location on both tear down and reassembly videos. Thanks for watching!
Hi jdmrvip, What missing footage? I just scanned this video and didn't see where any steps are missing or footage omitted... What part of the assembly process are you working on?
Oh, i see - sorry, thought you were referring to segments other than my note at 3:47. You assemble the rear ring gear hub and base exactly the same way as the front ring gear. For the low reverse piston: if working with lip seals, ensure your lip seals face down towards the bottom of the case. The lip on all lip seals faces the direction that the apply fluid is coming from.
Okay I stopped I’ll read this again when back on it. Thank you so much. I’m hoping to build my first transmission 🙏 Do you have anything you want your subscribers to donate to?
Thanks, man - you will do fine. Im getting reqdy to do another TH350 tear down later this week so will be up on the channel sometime next week. I have a link to my "buy me a cup of coffee" page on all my videos where you can donate if you'd like to (no amount is too small :)

Thank you for the kind words and your views, Private Data! Appreciate it 🍻!
Great Stuff! Keep it coming!!!! Best transmission guy on youtube!
Thanks, brother!!!
Will do
Thanks for posting this super easy to follow along great setup man.
Super easy to follow. Great job
Thank you, Steve!

Does the washer under the sun shell effect stack height I assume it does since it rides on the thrust washer.

Can you check seal integrity of low reverse with the pan dropped and tranny installed?

Hey Nick i have a question,
Do you have a video to the missing footage?
I’m literally following step by step and scared about those steps
Hi jdmrvip,
What missing footage? I just scanned this video and didn't see where any steps are missing or footage omitted...
What part of the assembly process are you working on?
@3:47 please help
