1G What did I break? W4a33 trouble

[SasaniFab]

So i took my cAr out for a spin, few launches and pulls.... pulled the car in and I heard an audible wine when the car is in drive. The car is silent in neutral. The car will stall when I put the car into drive. If I rev it... the car moves and shifts. Any ideas?

Trans pump usually. BUT your car shifts. Could be anything like a rear diff or transfer case man.

I wouldnt continue to run it, you are likely spreading crap all through the transmission from something you damaged, pull the pan and filter and report back.

Pan is clear? Magnets are clear

Thats strange. I would lean towards a trashed converter in that case.

Trashed convertor? Is that rare? Its a practically new spoolnator. Wouldnt it make noise in idle also?

Time to tear it down.

I broke stock auto transmissions faster than stock manual.

Its not super common but convertors do fail in lots of different ways, theres not alot else that I can blame with your description.

Can you take a video of the whine?

Also, holy SHIT kronus! Where you been man!

Usually when they start whining while driving it’s cracked transfer gears.

Yah the pan is completely clear, I did a few hard launches. My car is making 600+. I'm gunna pull her out tmrw, I have the Jeff bush trans gears anyway. Some people are saying bad t conv, bad trans gears or my planets are going. I'll find out tmrw. The strange thing is my pan is crystal clear, nothing even on the magnet?. If the car is In neutral it's quiet as can be. If I put it In drive I'm reverse it will stall unless I rev the engine.? It's not a knock or rattle just a low pitch wine, stop when In neutral.

If you have the billet transfer gears they aren’t broke. But when the stock gears first start to crack they don’t start shedding metal. They fracture and then just break all at once.

I’ve seen baskets crack, o rings fail, planetary gears fail, clutches of course, and just about every other part in those things fail.

I’ve even seen valve bodies cause issues like you describe and nothing was visually wrong anywhere during a teardown.



Make sure you post up some pics when you get it apart.

Im pulling it out tmrw morning so Ill be sure to keep everyone updated. The strange this like i said is it still will drive, just feel like theres resistance. The transfer gears are stock, i have the billet gears ready to go

The real question is.....if the torque converter is going, wouldnt it still make noise is neutral? The tc is still spinning in park isnt it.....

Yes, its still spinning but its under little to no load, its sounding like the bearing is going in it maybe. This video kind of captures the sounds.

sounds like that. Very strange.....Arent these spoolinator tc just re purposed oem units. I hope my tc isnt f***ed....they arent cheap

 

[SasaniFab]

Havent found anything yet.

So im comparing torque convertors. The spoolinAtor front section is very loose and spins very very easily. When compared to a stock its much stiffer. Like comparing a ball bearing to a journal bearing?

 

[motomattx]

Its a tough one, its not like its a rear wheel drive Chevy where it only takes two hours to stick a stock converter in and give it a try, but thats almost what your going to have to do unless you have a torque converter rebuild business that can open it up and check it out for you.

this normal?

 

[motomattx]

Most aftermarket converters are just restalled/modified stock units, you could call the company and ask them if thats normal or not.

I wish i could call, sinister speed doesnt have a number. Going to email them.

Right, which is why im concerned the spoolinator spins 10x more easily .....very loose. Ill see what mike says

ive witnessed the complete opposite. hell i broke a shep stage 2 trans on a 30mph roll in my car meanwhile my tuner has went 10.20s with a stock auto with just a converter.
