mine had alittle discoloration when i put it in not as bad as his but i think its from the lockup clutch

 

Call me stupid but does a 4l80 not have the ears to turn the front pump like a 4l60? thats what i see different

 

Looks like it got VERY hot...

 

Those are hot spots from the converter clutch slipping. Dave told me that he uses that paint specifically because it changes color with heat, so he can tell if the converter clutch has been abused before teardown.

Other's have said that they lockup their Yank, so I tried it. I suggest to others DO NOT TRY IT!! I will not be trying that again. (and my truck is slow....) TFT's never went over 175.

 

Soon as I read the main screen, I saw your name AKlow. I had a feelin this was a thread u started & not simply 1 of your replies to someone else's thread. I guessed it was your bad luck thread, but for a different reason - I thought it was tranny related not stall. I viewed pic & all I spotted was the discoloring, & thought heat! I gettin dangerous w/. my knowledge!

Did u tell Dave what u did? Perhaps he knows already.
Clever, I wondered why converter co's had different colors. So, it's not only a recognition this color is that brand. Slick.

Just get a Circle D!!! U can lockup theirs @ WOT! Oh, you're not slow. In the head, maybe.

 

every Yank I've ever pulled has had a bit of discoloration on the front cover but never could tell it by the way it locked... I'd say that is excessive though. I'd definitely have it cut and a new clutch slapped in it.

I really like Yanks products and have had great luck with them but from my expreirnces with numerous converters and setups, get a GOOD QUALITY multi disk unit if you are wanting to lock it up under power.

 

Wonder what the clutch itself looks like?

 

I really like this converter also. It has very good street manners. It also DRASTICALLY improved my heavy-*** truck getting off the line.

It shipped out yesterday for cut/clean/clutch. I'm not taking any chances here, seems like the clutch was still working just fine, but with the 3-4 clutches not holding at all, I couldn't lock/check the converter clutch to test it. The tranny fluid was still clean & pink, but smelled like clutch material.

At any rate, I probably won't see my converter back for a few weeks, so I have a few days to decide if I wanna change my setup. Maybe somebody local wants a new Yank SC3000...

 

Wow, 1st time you've seen that in writing, huh Roger?
Someone local? In AK? You'd be better off tryin to get him to give u a trade-in on an upgrade. An upgrade to a ...

Seriously, I know you're up there, & IDK who's pickin up shipping cost(s), but well decision time & u don't wanna decide after incurring shpg 2x I'm sure...u know your options. I'm curious on how this is gonna play out.

 

Me too, was thinking dirt or dust..


TOM get of Circle D's nuts
