Re: Jane's 4t65e - Starting to assemble
Thanks! I totally forgot about the Teflon ring installation on the input housing assembly. Not much to say. Here's those pictures
Re-sizer on. Waiting for installation

Re: Jane's 4t65e - Starting to assemble
Little more progress today. Reverse band, input housing and driven sprocket support in to check the total endplay.
Almost 0.032" Was a little much
Fortunately, I had the selective I needed on hand. Replaced a white with a brown. One of the benefits of building multiple transmissions. Spare parts.
Toss it all back in, including the 2nd clutch drum, because hopefully it won't have to come back out.
0.009"... We're good here
Ready for this!!
It's in. My new avatar
It's good. (For now)
That's as far as I can go up top until I get the 4th clutch hub.

Should of said something about the 4th hub.....I think I have 3 of them (one new and 2 from transmissions I've torn apart)

Re: Jane's 4t65e - Starting to assemble
Well, to be fair, I kinda did.
Didn't even think about asking for one here. It's not a huge deal though. They're only $30 shipped. When we do my brother in laws trans, I'll send a laundry list of needed parts.

Re: Built 4t65e - Quality takes time
So since I couldn't do anything else on the side, I moved to the bottom
Thermal element in
Filter seal 2-1 manual servo seal and 2-1 manual servo installed
Check to make sure the servo pin engages the band
Ready for the accumulator assembly
All together
But before I did this
I did this, per the instructions
Forward servo in
Again, check for pin engagement
Threw the filter in. James said go crazy with magnets. This is only the beginning
HeliCoil kit, 4th clutch hub, and solenoids are on their way...

Re: Built 4t65e - Quality takes time
Hmmm... From the research I've done, the only TSB I see related to magnets and the PCS is one adding a magnet. Something about replacing the one thin square magnet with the new larger round magnet. Also adding another to the filter body (like shown). In fact, that's exactly how the 2 year old serta unit I pulled apart was configured.
Do you have any more info on this? And thanks for the feedback!

Magnets for your magnets magnets!
Looks good man, nicely done. The next trans I do is getting some PPG Dog Box love.

Re: Built 4t65e - Quality takes time
Same TSB, some of them online are missing paperwork regarding the magnet placement though. Placement is really what is critical here as there is reason for them being placed on certain areas of the pan, the new round magnets are what I would go with over the squares as the squares have a tendency to become overloaded quickly, that was the purpose of the TSB. While im sure that you probably wont hurt anything with the magnets where they are, I wouldnt risk potentially having an issue with interference from the magnets by going "hog wild" with them. The two on the plan are plenty trust me, having multiple magnets attached to the filter and in locations that werent originally designed for them could cause more issues then they help solve. Given how your building the trans I dont think your gonna have issues where the magnets need to scoop up a ton of material, and the rest the filter and regular maintenance can handle just fine. Hate to see you develop some phantom issue as a result of magnets.

Re: Built 4t65e - Quality takes time
Hey thanks! Yeah, Every time I've pulled a pan or disassembled a trans, the magnet (singular) was always beyond capacity. I plan to be super vigilant about fluid maintenance, so even if I had the standard magnet setup, I wouldn't worry about it getting overloaded. But they're $1.30 each, so why not, right?
That dog box is in a whole different league from what I'm doing here!
That diagram you show for magnet placement seems to make sense. It places them close, or as close as possible, to the fluid dump points. Just my opinion though, not an engineer. I may still order up a doughnut mag, but only because it would go around the protruding portion of my drain plug. Extra insurance for that RTV to keep it from moving around in the aluminum pan. We'll see. I still have time to figure all that out. Like I say, I plan to keep a close eye on fluid condition. Having a pan with a drain plug will make it way more convenient to drop and inspect/clean everything.

Re: Built 4t65e - Quality takes time
Yeah It will be the first time i open up a manual gear box, but I am saving and should be able to pick up an R33 when they hit the 25 year mark, the only issue I have it the motor setup I want is in Australia and them Aussies are selective about who they sell to. Otherwise the gearbox is the standard manual that comes mated to the RB25 engines.

Re: Built 4t65e - Quality takes time
I didn't understand half of what you just said. :th_laugh-lol2:
Anyhow, Got my solenoids today. Again... Our postal service... Sigh
Fortunately, they were pretty well packed. They made it in tact.
Old PCS vs new
Old TCC PWM vs new.
The shift solenoids are nothing special, so no pics of those.
I'm certain they test the solenoids before they ship 'em, but I figured it wouldn't hurt to check anyway. Doesn't cost anything.
The 1-2 shift solenoid goes back in the bag until I get the new 1-2 valve
There sits my almost done valve body
Leftovers
Tossed the dipstick tube seal in. I've found that an O2 bung plug is the perfect size for keeping stuff out while it's being stored
No clutch hub today. Hoping to see it tomorrow.

Re: Built 4t65e - Quality takes time
Nice work. Your magnets post reminded me to get some before I do my shift kit. Honestly I don't think you'll have any issues from your magnets. I will put two where the tsb says, and I'll do a few on the bottom of the filter like you did. The filter is steel, therefore it will prevent the magnetism from going up past it. Not sure I'd want to install any more anywhere else, but that will be like 4 or 5 already, that's enough lol.
Not sure what magnets to get, and from where. Think I'll use 2 hard drive magnets on the underside of the filter.

I didn't see the filter collar install... did that happen on page 4?

Re: Built 4t65e - Quality takes time
I have 4 neodymium magnets over near the diff drains, rtv'd to the aluminum pan, drain plug was helicoiled and modified for a neo rod for easy accumulation inspection.
im very nearly to putting a bypass filter setup on the cooler to make sure the fluids clean even with that screen on the pump inlet.
get the tiniest scratch inside the filter seal bore or a non flat pump and as soon as the filter starts to plug youll start sucking air, then wonder why your line pressure fluctuates

Re: Built 4t65e - Quality takes time
Thanks. I went with the generic square magnets because they were cheap and available. $1.38 at my trans shop vs $8 for the round GM magnet from Ebay. I thought about using Neo magnets, but I read somewhere about them losing their pull at higher temperatures. That could have just been someone trying to sound smart though. The other reason I went with standard magnets is their size. Sure, the Neo magnets are super strong, but they don't have as much surface area. I think they would fill up fairly quickly. Plus, it doesn't take much pull to grab a metal particle that's suspended in fluid. That's my theory anyway.

Not sure what page Bill. Tapatalk vs web browser. (?) Post #87. I kinda glossed over it.
I should have posted a picture of just the seal. It's kind of important. I did take one though. Here it is
