Had someone replaced the Quadrajunk with a Holley?

Why did you store it for free? You could be flying to training camp with her money.

I hate carburetors in general, but my dad fucking HATES Holleys. Like hates them with the fire of a thousand suns. I'm pretty sure I could call him right now and only say the words "Holley carburetor" and I'd get profanity.

He said the only reason guys think Holley's are easy to work on is because they have plenty of experience.

He had one on a tandem truck in the 80s. I think he rebuilt it 3 times in one harvest and said fuck it. Quadrajunk is still on there. He will not own one.

Quadrajets are interesting. They are the closest thing you can get to fuel injection in a carb with their seemingly endless tunability and stepped metering rods but they are also infinitely more complicated than a Holley Carb.

Carbs are confusing as hell as it is, at least on a high HP motor, I think a Holley is simpler than most. Probably why they are so popular.

Also why I went with fuel injection on my car.

Dad can make them run forever. And if they don’t he can kit one in like no time. If I tried to kit one I’d have like 30 extra parts and be saying, “...fuck”.

A lot of old timers can rebuild a Quadrojet in no time. I took auto mechanics in highschool and my shop teacher loved them things like they were made of gold.

I put in a brand new 5.4 3v in a04 f150 yesterday. Started on the job around 9am, customer picked it up done at 430. And I took lunch, needed to breathe lol


I was on fire.

I'd say you're patting yourself on the back and you could get a sore shoulder...


Let me help you out.

Oh I'm definitely patting myself on the back.
Guarantee that's in the top 1 percent of that job getting done

I would like to tell the saga of my 4l60e transmission.

So im not sure if I mentioned it here, but after I built the motor in the truck, got everything dialed in, and about 3k miles on it, the 3rd/4th band in my 4l60e let go.

Because I already had a good converter, I told myself I would skip the 4l80 and do just a built 4l60e since I'm putting out less than 500 crank horse in the truck and plan to stay that way. That way, little bit cheaper trans, easy install and go, and keep my same converter.

So I have a local known guy that only does 60s build me a trans. 1100 bucks. heavy heavy built 4l60E. And now if you know anything about 4l60s, a heavy built trans can only handle about 500hp, but I digress.




Me and my buddy install it ourselves in his shop, trans shifts great. But there is a problem. The converter wont lock up. We try tons of stuff, changing tune, commanding it to lock with the laptop everything. And it wont. This points to a converter issue. But, because the trans is warrantied, I take it to my trans builder just in case. Turns out, converter is trashed. When the 3/4 clutches burnt out, they sent so much trash into the converter that the lockup clutches cant engage.

Ok, so the truck sits for a week, I order a new converter from Revmax, (awesome company btw) and my trans builder puts it back together. I pick it up, drive it home, drive it to work and back the next day. On the way back, I notice it gets to 190 degrees trans temp on the highway.. now, this might be normal for a normal setup, but I have a big Hayden bar and fin cooler that should keep the trans about 40-50 degrees cooler than that. I chalk it up to brand new clutches and drive it to work again the next day. Problem is.. I only make it about ten miles before I lose EVERY gear. Trans is completely wasted after only about 120 miles driven.

Once again, I've got warranty, so I have the trans guy come pick it up and pull it to his shop. He opens it up and tells me its the most roasted clutches hes ever seen, and it wasn't his build that did this. I'm pretty easy going so I say ok well lets find out wtf happened.




He rebuilds the trans with all new clutches, new pump, new valve body, everything trying to figure out what happened. Everything is new and golden, and he reinstall trans. THIS TIME, he puts a pressure gauge on just to see whats going on and immediately sees an issue.

This is the part that you guys will like. This thing has no pressure off the gas. There is NOTHING in the trans that should allow it to run 10psi idle and 15 in reverse. It should be 75/120 respectively. Under load, pressure is fine, but off load it has no fluid pressure. Now, a 4l60e keeps a band engaged when its not under load, so this is what caused the built trans failure, (and likely the very first one) since it had no pressure, the clutches burnt up trying to engage constantly. With the scan tool hooked up, the voltage to the pressure solenoid is solid on the gas, and going crazy off the gas, which is why the solenoid isn't commanding pressure when its off. So, we switch out the solenoid, same thing. We mess with the tune, same thing. Really starting to piss me off, and hes stumped, since we can command the pressure solenoid with the scan tool to hold pressure and it will. I start thinking about it, and I told him that I noticed on startup sometimes, the trucks dash lights would waver and dim just a tiny amount, and I wondered if that had anything to do with the voltage fluctuation. So, I tell the trans builder that I have an extra alternator at home, and lets just try that before I go to a vacuum modulated pressure setup and get rid of the electronics entirely (another 200+ bucks)

We stick the alternator on and INSTANTLY have pressure at idle, 75/120 just like it should be. That ****ing alternator wasn't supplying the right voltage to the EPS and burnt up the god damn trans in 120 miles! I have never seen anything like it in my life!

So, now here I am, paid the man for the extra parts and labor that my truck burnt up with its shenanigans, so deep into this 4l60e I could have had an 80. Lesson learned I guess!



TLDR; Moral of the story, 4l60Es are pieces of shit and check your charging system folks!
[Reply]

Wow that's crazy shit. Your alternator burned up your transmission. I may have never figured that shit out.

In a much more basic scenario I had a 1979 TA back in the day and the trans went out, I bought another one and threw it in the car and that one went out shortly.

Had a pinhole in the trans cooler in the radiator that was slowly seeping water into the tranny. Somehow I missed the old trans had water in the fluid, not sure how.
[Reply]

Yea, I never in my life thought of it, but when he told me the voltage fluctuation was what was causing the solenoid not to provide pressure, that little dimming came to mind instantly. I luckily had that other alternator at home (which I knew was good since it was the original alternator I had in this truck) and I figured why the hell not lets give it a shot.
[Reply]

Was that 79 TA trans a th350? Cause thats just a piece of shit 4l60e without electronics lol
