TC Problem?

[Jake]

I noticed this the other day at a drive thru, i could tell cause of the building right next to my truck. I had the truck in neutral and was playin with my lockup switch. I didn't notice it at first cause of the noise of the engine, but when i locked the TC i noticed less noise. So i unlocked it again, and it sounds like a "shhhhhhhhhhhh" kind of noise, when i lock it, it goes away. Is that normal or is my TC takin a dump? The TC still works fine, locks up firm like it should.

I'd have to say it was fine but I don't know much about these autos I'm a manual kind of guy, this is my first auto I have owned and I'm allready disapointed. But I'm thinking the noise you are hearing is the fluid running threw the tc, I could be wrong tho.

the noise is most likely jut the sound of the fins in the tc spinnin thru the fluid at a different speeds till they lockup

That is what I thought, you just worded it better then me

[Jake]

Thats kinda what i thought too but wanted some other opinions.

Sounds to me like it is ready to take a dump anytime

A tc can go out at any time so he maybe right but my th350 had a tc that made a noise similar to that for over 100k miles and it still worked when I took the motor and trans out and sold the van, I didn't have own it but 2 days but my grandpa owned it since 79 and it had 2 rebuilds, one at 320k miles and another at 590k miles. I built that small block to make around 600hp on pump gas it was going to go into an s10 but I sold the one I had to buy a better canidate. Sorry for the hijake

their is at least three big moving parts in a tc...and they dont all spin the same direction. then you have your lockup in between your turbine and cylinder/TC cover. i dont understand how they dont make more noise than they do lol. and thats just the TC....


i though you were the guy to talk to about TC's? lolol
