Great play by play! Very impressive!! I struggled with installing my pump, finally got it installed! When I installed new bushings into the pump, the ID shrinks a little. I finally did a fit check with the shaft, and did a Demetria clearance measurement, just to be sure, but that’s what was hanging me up. I needed to lap it to the bushing. I used a plastic rod that barely fit the bushing, with a 2 inch slit down the end. I put some 600 grit into the slit, soaked it with compatible or something that is not detrimental to the system (WD-40 works pretty much everywhere, lol), attached it to a drill and started lapping. I cleaned it out and fit checked it with the rod several times. Replacing the paper each time. I kept doing that until it fit properly. I used lots of paper. Remember, if you love her, you lube her! Now you know!
Thanks for the clear steps. So many vids forget to show the thrust washers or little things like that that can be over looked and end up screwin you over later in the assembly or down the road... great vid...😉
Thanks for making this video. I assume the intermediate clutch pressure plate rests on that rim of the case and does not touch the direct drum is that correct? When I move my input shaft, I can see the pressure plate move slightly til the tags stop it. I think my drum assembly isn't down far enough but I can't tell for sure.
10 to 15 thousands, that's super tight I shoot for 50. Have you ran a transmission at 10 to 15? Just asking because it seems like after it gets warm it wouldn't release the clutches.
Good morning., have another question about installation of the torque converter .... Since the torque converter sags ever so slightly from its own weight when resting in the transmission, prior to bolting to the flexplate,, should you lift it up ever so slightly (take the weight off) as you tighten the first torque converter to flexplate bolt? Or just pull it forward and bolt up without lifting on it?
Why all the trouble to machine down the pistons to fit a extra clutch and steel if it’s not a race application? I’m about to pull my th350 because at 650rwhp I’m blowing through the torque converter. Ordering a new Ptc and gunna out a brake in this tci th350
Brian Swayne Stock number of clutches in my tranny has survived 10 years of abuse in 4 different hot rods from 400hp to 700hp. So I just asked why in a basically stock application it would be needed
Your video is quite impressive, and I wish I had your knowledge. I am a newbie, and I am wondering if you can answer a question about air checking the pistons. how much air pressure do you use? I am building a TH350 and was checking the pump piston (intermediate apply piston I think its called) with the pump sitting on the bench by itself, and I have positive, full piston travel with 25 psi. But once I stop feeding it a constant air flow (with the rubber nozzle still held tightly against the pump air feed hole with no leaking), then the piston slowly bleeds back down over about a 15 second period. I read that this can be normal since the piston isnt actually pushing against any clutches, but these are new lip seals. I pulled the piston and inspected the seals twice now, and there are no damaged or rolled seal lip. the piston bores are in great shape and overall the pump is in good shape.. I am a newbie. Is this normal/ok?
Thanks for Video. Can someone pls tell me the secret of the two missing teeth at some Direct Drum steel plates. In which way do i have to install them ? Shal the missing teeth align with the oilholes in the Drum ?
Well you could not switch between forward and high. Are you sure their wasn't 5 in high. The standard is 5 in forward and 4 in high.You will have to machine piston.

This is the best, no bs rebuild video for the turbo 350, much thanks!

Thank you for this video!! It is greatly appreciated.
How much horsepower/torque is this good for?
Also, can you rework the valve body to turn it into a trans brake like we can on the Powerglides?
These builds handle 600 hp. You can purchase transbrake.

yes your correct
Awsome tranny class ! I understand alot more on assembly but not how every piston works in tandem or when band comes into play ! Thank you sur

Just tighten bolts spacing should be less than 3/8 inch.
Muy bueno y pedagógico, con algunos detalles para ser excelente, mil gracias por esos conocimientos. Saludos fraternos

The more clutches the more HP. I like to do it right the first time.

You should be good to go. I use 100 psi.
What does removing the 1-2 accumulator spring accomplish and do you recommend removing ?
Makes the shift firmer. That's what the accumator does,it softens the shift.
@@BrianSwayne 👍thank you for your response .
Thanks for Video.
Can someone pls tell me the secret of the two missing teeth at some Direct Drum steel plates.
In which way do i have to install them ?
Shal the missing teeth align with the oilholes in the Drum ?
You just have to line up marks that's all.
💯
51:19 in park the shaft don't spin and other gears the shaft spins freely? Is that normal
If your talking about the output shaft then yes in park it does not spin. It's locked in park.
@@BrianSwayne the tail shaft(output) shaft is locked in park but what about the input shaft does it need to spin in park
@@davidl5121 yes input will turn. Only output will be in park.
@@BrianSwayne my input shaft won't spin on park only when I switch gears it spins freely
@@BrianSwayne did I install something wrong!
I am lost on my direct drum I took it apart it had five steels and clutches but now it will only hold four
Well you could not switch between forward and high. Are you sure their wasn't 5 in high. The standard is 5 in forward and 4 in high.You will have to machine piston.
@@BrianSwayne ok so four clutches and steels are normal for the dierect drum
@@sherrodracing4345 Yes as long as it's not over 600 HP and no transbrake.
