4l60e case bushing failure... Has anybody seen these fail and get mangled and end up in the extension housing? I saw one of Precision's videos where they found one in the extension housing. When I replaced mine, I didn't see any lip on the case so I knocked it out and the correct bushing driver and handle went through the hole & out too. When I installed the new one, I had the notches in the wrong location, so I knocked it out and rotated it and drove it back in. I honestly don't remember if I installed it from the inside or outside--I did it back in the Fall...
Was there a reason why they show it replaced from the inside? If it matters, it's a 2007 4WD case. I couldn't find any lip so I think it may not matter which direction it gets installed from, as long as the notches are facing inward and about 7 & 1 o'clock(s). Anybody?
I now worry that it might end up in the extension housing like their video, so I'm thinking of knocking it out AGAIN and reinstalling it with a few drops of red Loctite, just to be more "worry-free." I don't have another one, so I'll be reusing it (it was a new bushing that was pushed out with the correct size driver.) The trans isn't fully assembled yet. Please let me know what you think.
Thanks everybody!

In my opinion bushing are a onetime install, if for some reason I have to knock a new one out I will not reuse it. I for sure would not install the same bushing three times. If you must reuse it, install it with green locking compound.

If you want to laugh hard, watch his son trying to act like his dad and dissasemble the 4l60e and while trying to sound professional, he calls parts with some weird names ahahha. /watch?v=WRgrntxaJ58&t=579s
I've found only one guy who uses like 1/3 of your groundbreaking mods that you shared and it's "
Express Auto & Transmission David Lee". I bet he took the info from this forum.

I like watching his 4l60e family videos, he disassembles them in 10-15 minutes. I don't like the use of Z-Paks--that's all he seems to use.
He had a good mod for blocking the TCC--he takes the spring out and puts a checkball in, then the spring, then another checkball, and you now have a blocked solid on/off. Don't need spacers, don't need brake line pieces, etc.
So back to my bushing... are you saying don't put the unused but pushed out with #71 bushing back in?? order another bushing? don't put it in with a few drops of red Loctite at like 3-6-9-12 o' clock?
Geez, I may have to wait til the 1st of the month... I may have to skip that 300psi gauge... and I didn't get that bypass cooler and 1800-2200 converter yet... I'll be coming up on a year without a running vehicle the end of the month!

Thanks Brian. If I can't use the red & need to buy green, it'll probably cost less to get a new bushing.

TCC valve is easy to block by just flipping the inner valve around on most years. That's it. No spacers or checkballs or anything. Some years require a hair more effort but not much.
I'm saying if you've driven a bushing out...I don't like to re use it.
So if you have an "unused" bushing that got driven into the case...then driven back out...don't use it. Just personal preference. If you're in a bind, some loctite and it would probably be fine. Green preferred but red will work in a pinch.
And holy crap...a whole year to build 1 4l60e?

It's my only ride so everything I need must be delivered... including groceries. I've been living off Walmart groceries at 10 bucks/delivery and Amazon Prime for Poor People.
It's the Transmission from Hell. Many, many setbacks & delays. Broke a Torx Plus on Day 1 of disassembly... had to order drill bits to drill out 3 bell bolts. Wrong pump for the input drum... many parts ordered for Non-ISS only to find mismatch when parts arrived and had to reorder... some Sonnax parts on backorder... shiit like that...
I'll try to find a new bushing... that'll add another week... Thanks for your reply.

OK, I found the case bushing for $9.99 or the whole bushing set for $19.83 so went with the set...
Does it matter which direction it's installed, besides the notches pointing inward at approximately 8 & 2 o'clock when looking at it from inside? I mean, can it be installed from the outside? Thanks.

Is there any reason why you (and some others) install it from the inside? There's no lip like the pump bushing and no taper to the bearing. I wondered if they were installed from the inside so the notches didn't gouge up or get hung up on the case bore...

I think I was just as much in awe how fast he gets retainer rings off, like reverse input rings deep inside the bowels of the case...

I install from the inside, so I don't have to drive the bushing as far to place it just below the inside of the opening. If you install from the backside you have to drive the bushing a lot further. I don't like to press a bushing any more than I have to, to avoid the risk of the press fit of the bushing loosening up.
