- čas přidán 28. 05. 2023
- I was asked to disassamble this transmission that was supposed to being built as a high performance, high horsepower unit. Well, came to find out that this unit was'nt even built for that kind of power as the owner of this transmission is planning on using it.
I really did'nt wanted to film this but I did per his request. We will be improving this transmission to handle the kind of power that he intends to push through this transmission. - Auta a dopravní prostředky
Hello Hiram from Australia🙃
It's great to have you back with us👍🍻cheers to the master..
Man, I live Hiram's channel. No family drama, just Hiram and some mechanical goodness getting together for some quality time
Good teardown and an honest evaluation and opinion. Good thing the customer has found you. Stay safe and hope you keep posting these videos Hyram!
Excellent channel.
Can't wait to see the new 10 speed transmissions taken apart..
Thanks for another grate video. I Appreciate all the time It takes for you to make the video and To edit it for allot us. Thanks again.
Hiram there are a lot of transmission channels but yours is the best. Great information and no BS. Thank you for doing this for us.
Great video with honest opinion. Hope we get to see this unit put back together soon
Brother.. love your videos when i first started building i would watch your vids!
Great to see you back please show the build sir!
Your seriously a MASTER
Thanks for sharing your knowledge with us.
That's a shame, they say you get what you pay for, but that's not often the case. Thanks for taking the time to make the video.
Hey Hiram, glad you recorded this. It's really important for people who are buying a "racing" transmission and are getting robbed. Also, good to see that you're doing ok. ;)
Unfortunate reality that many builders do not do what they say they do. Life's too short to live with those realities for eternity. Hopefully, the builder makes it right and provides the parts to complete the build per the specs it was sold as. We don't do anyone a favor by not calling out the shortcomings. Hopefully, this will refocus the direction of the builder and benefit future customers. Thank you Hiram for your willingness to share your knowledge, expertise and demonstrated integrity!
Great work!
On the bright side, they cleaned and painted the case for you. Have a nice Memorial Memorial Day.
Awesome video, I’ve learned a lot from you. But I would love to see how you put together a 4l80e transmission, I think that’s all I need to finally rebuild my own 4l80e… thank you so much 💪🏽💪🏽💪🏽
If you ran an expo. I'd come meet you. Thank-you and shake your hand sir
Hello. Wow man. Knowledge is GOLD. I hope you'll be taking my 4L80E next week to see what failed inside and repair it to new. I'm waiting to hear from you, Vinnie has replied today to me email asking about this repair. Mine is a 1500 HP rated 4L80E that 's been in my car for 4 years behind only 450 HP. But now my new engine went in last month and my turbo kit is going on....1300 RWHP is the goal. Roll Racing events.......... But now I all of a suudden have this weird issue of grinding/vobration/noise. Vinnie has my detailed email. Thanks.
You got into "this", because your customers trust you to make the right parts and know you will make sure the install procedures are followed.
Refund and a Court date... Cool vid Thanks. Brotha.
I've put a bunch of power thru my 4l80. I used bw high energy clutches, internal dual feed, 3-4 accumulator delete and a basic shift kit. Drilled the pump area for the billet tcc release. All new bushings, seals, and molded pistons. It works awesome got 20,000 miles on it now and been 10.40 in a 4wd Silverado turbo 5.3
No billet shafts needed for that. But if you pay for them I understand wanting what you pay for. I always race or beat on it in manual 3rd cause I don't have the sonnax overrun clutch kit.
Thanks for sharing. 👍
Never take someone's word for it.
Why would this customer not just bring this to you in the first place?! I bet he is wishing he did!
That is what I was wondering, and he must have not had faith in the other builder to get Hiram to do a tear down check.
Good job
Your videos are awesome, most knowledgeable guy on CZcams! Where’s your shop, I need my 6L80 rebuilt.
Watch the customer say "just put it back together the way it is". "I will fix it later"...which means never.
Thanks sir
thanks for doing another 4l80e video if you can find the time can you do the build up video on it? thanks brother
Hey Hiram, I’ve watched a couple of your videos now and they’re super helpful! But I’ve just got a question related to a 4L60E in a 97 C2500 Chevy I just bought, the rear seal was leaking and I ended up losing 3 / 4 going down the freeway before I actually realized.
3 does still grab when coasting down a hill and holds the vehicle back like it should but as soon as I press the gas it slips out.
I’m wondering if the torque converter being empty would cause something like this and if I drained the fluid and re-primed the torque converter if it may fix something like this without rebuilding it.
Love the videos
Where are you located?
Can someone explain how the 4L80E manual 1st and 2nd ranges work?
In the description it states M1 - 1st gear start, automatic upshift to 2nd. M2 1st gear start, automatic upshift to 2nd and the only difference is that for M1 you got the engine braking in both gears, while M2 it is only for 2nd gear.
Effectively two ranges that do the same thing and hence it making a 1-2 and 2-1 manual shifting impossible?
Are there kits that lock out the 2nd gear in M1 altogether and, correspondingly, the 1st gear in M2 for a 2nd gear start?

I have a TH400 in a 1988 R30 2wd. Would a 4L60E be a good replacement to get another gear? Is there a way to keep the mechanical speedometer with the 4L60E?
Hello Hiram. I have a 2013 6L90 that I need to replace or rebuild. I was wondering if I rebuild the transmission myself would the dealer still have to program the transmission/ecu since it's the same transmission?
Have you ever had one slip in reverse but when you unplug the electric plug it don't slip anymore
When you pulled the extension housing and a used bushing was still in there….
How much do u charge for this?
Very smart consumer is taking zero chances, I'm just hoping the engine work is genuine and that a credible mechanic delivers on his price quote. A lot of people running under the falsehood that there is something they can actually do against this AT parts swapping rebuilder when that route only pays the lawyers and winds up costing twice what billet costs. Pointless exercise in stupidity, if they are any good in this game of lying, they are already running under a new name somewhere else while being untraceable too. Which is exactly what happens when they can be forced into court - they disappear first. And that means going after them is a total waste of time and lots of money because the lawyer is always going to get paid out of your already bleeding rear end. Best option is to give that shop a trashing review thru the better business bureau as a means to warn the next guy wanting to buy billet parts installed from that outfit. Bad news for Hiram, he's now in the middle of this and he didn't want to be. I'm confident that the guy that hired you Hiram already suspected this could be the outcome, so now his dream ride is just going to cost a bit more than he has already paid out. I would forget about the other guy's placements of check balls and do it your way, all the way, Hiram.
h unfortunate to find the the the old sellar was lying it's pretty sad but in today's world it's kind of standard equipment sorry to say not a good scenario
What is the name of your company and where are you located? I have a vw 09A that needs an overhaul. Thanks.
It's hilarious what people think a performance build is sometimes it could be a shift kit maybe an extra clutch in the drum with a shift kit maybe even no shift kit with just red clutches. The reality is you get what you pay for, Transgo is a joke if you're trying to make any real horsepower. A real performance builder has a lathe and a mill to machine the parts the way they need to be machined. I have been a building for 15 years you can always learn more I don't care if you have been building for 30 years you can learn more.
I always wanted to rebuild a transmission. You make it look easy, but I know it isn't. My 1993 RV has a 4L80E that shifts rough. Since it only has 30k on it I am guessing the friction plates have deteriorated.
Hard shift or soft shift? ATs will soft shift or go neutral when they are about to go out. 4L80E produces some of the highest line pressure of any AT produced (300psi>), and are known to sometimes produce too much.
@Jet Black Fox Thanks for the reply. When you stop and try to go it won't go at first then you can feel it go in gear hard. Higher gears are smoother.
I would love to get in contact with you to see if you wouldn't be interested in over hauling my transmission or replacing it. It we are close to one another
At 23:05 you lift a part out of the transmission I can't lift mine out of their what the heck do I do to get it out of there and why did it do this I hope you have the answer
By the way you have one of the your videos are the best I have ever seen on CZcams please don't stop making them. Do you have one on a 4L 65E?
Hiram we’re is your shop location
Texas USA
Pretty sure he's in Houston
Impending lawsuit...
Typical parts pimp trying to upsell something they don't have for more profit. The seller is a complete fraud.
