4L60E Input Drum Leak Testing

[@nyertsenginetransmission3861]

Can never learn enough! Have been following you for years n have learned alot thanks for your time and videos

[@Roscotech]

Thanks Hiram, I actually found one leaking (input drum shaft) on the 60 I am building now. I have the same blow gun and put the tip through the exit hole inside the drum (all the pistons were out) for 3/4 then blocked the apply hole in the shaft. I used brake clean in the bearing/shim pocket and then applied pressure. Only tiny bubbles but have been told that can get worse with temperature. Going to press the shaft out and reseal tomorrow. This is just what I needed to see.

Good information Hiram!! Thanks a million! Bill

[@FreeFLF]

Great video! Do you have any videos explaining how to do the repair? Where do you apply the jb weld and how much? Is it on the shaft in the area that goes into the drum and is right above the holes that go into the drum?

[@TAShannon1]

Thanks for the video. I just put together an input drum with sonnax sleeve, sonnax billet overrun, sonnax fwd piston sonnax input the whole 9 yards and was getting leaks on all ports.... disassembled and reassembled 3 times... turns out the air was leaking back past the rubber on my nozzle 🫤 😤

[@AutomaticTransmission]

Nice work!

[@TAShannon1]

@@AutomaticTransmission haha yeah thanks. 😆

[@DrFiero]

I just "Hiramed" one of my flat blades (with a notch in it). It makes it SO much easier to get the big lock rings out!!! :D

[@eulasdubois3181]

Love your videos.. Help me out big time. Any video on the shaft repair with jb weld

[@castledomeknives9395]

I really dig the JB WELD THING...... BUT won't a Hard launch or linelock break the JB weld "seal" ??

[@MitzvosGolem1]

Excellent videos Thank you . I have a 1500 Express 4.3 van. Now torque converter shudder. Orherwise good at 350,000 miles hauling tools equip.

[@AutomaticTransmission]

Look for the P1870 video I have on the channel. There's 2, one early and one late. Yours is the late. Do the valve flip to make it on/off instead of PWM. If shudder goes away you'll be okay. If still there then converter clutch is already gone. Which is normal wear and tear.

[@MitzvosGolem1]

@@AutomaticTransmissionThanks. Shudder only happens 50-65 mph light load goes away when under load so tcc clutch is prob ok? Just dropped pan oil clean changed twice a year spotless no debris .Thanks for helping.

[@paxtonspeed]

Good video, never seen this one before.

[@josephadedjumoh6922]

SIR wit all due respect YOU are an excellent master. I gained more then a lot from ur teaching may God Almighty stand to help ur children as well as u've ur time to me this. Am very happy Sir

[@AutomaticTransmission]

Thank you

[@edwardsjohnson5387]

Great video. I like your old ones also. Question. During air check on 4t65e the top teflon seal has very small leak. It that acceptable or not? Thanks

[@jeffambrose5244]

Do you test them at operating temp? the aluminum expands faster than the steel shaft

[@thurmanjohnson6237]

What if i put air in the 3 rd clutch circuit, but air is leaking out input shaft in side the drum. Do i need a new shaft if not sealing? Let me know. Thanks. Thurman

Hello hiram from México thanks for tour videos

[@AutomaticTransmission]

Saludos México.

[@miguelbadillo6382]

Thanks for all the good knowledge. I have a question please. If I buy a 4l60e kit for a 2002 gmc will it fit a 2002 4l65e? Seals, clutches, I know that input shaft is different but are all the other parts the same. Thank you.

[@gabrielfranjul7171]

The drum must have all the clutches and pistons installed to do this test?

[@b.c6015]

Sonnax told me to use Loctite 609 .... it jb weld good for the vibration

[@mrwhite2628]

Good video Hiram! I like to see how others do things. It doesn't matter how long you've been at it. You never know what you might pick up. The only thing I disagree with. Is I would never use that drum that had the big leak in it. Sealing on a bench with JB weld is quite different that a drum is under a constant torque load. Although it work out just fine. That is a risk I would be wiling to take. Drums are cheaper than comebacks. Keep up the good work!

[@AutomaticTransmission]

Yeah, that drum I probably won't use. The replacement drum looked a little gray but wasn't leaking. I still do the same procedure eventhoug the drums don't leak.I used to use red loctite but opted to use JB Weld instead. The JB Quick also works but not too fond of it. At least not for this.

[@corbettknowles9942]

​@@AutomaticTransmission although I prefer to replace the drums when they're like that I have to agree with your assessment the J-B Weld Repair does work but also know that Transtar sells a repair kit for those upfront input drums where the shaft likes strip out the hole I believe it us called front input drum saver

Thanks

I wish I knew what compressor he was using with that Sonnex gadget.

Gracias... Muy valiosa información

I think I broke mine with a higher stall converter what parts/kit do you recommend that will last longer than stock parts?

So when do you wanna save a input drum? I have a drum with a small leak when I air checked it, the shaft has no play and seems ok.
