More TC woes....

[Goofyexponent]

I got a couple questions.

I did the manual TC mod. It works great...the mod does anyways. I tried putting the truck in drive today, then locking the converter. Not reccomended I know. But I did it as a test. My truck is now shuddering BADLY when the lockup is engaged...

My truck did not stall when the converter locked. It barely even labored. It just slowly started moving forward as if I was driving away, but I wasn't touching the fuel. I had my foot ready for the brake in case she took off, but I wasn't applying that.

I changed the fluid and filter. The old fluid wasn't the best, but it wasn't burnt or full of pieces. I also hrew in a bottle of Lucas tranny additive. It helped for about a week and a half...now it's back at it again.

I am now 100% sure my TC loockup feature is F***ed. If I leave the TC unlocked the shuddering is non existent.....ruling out other driveline parts. But what I don't understand is when it is unlocked, and I lock it, the engine drops 500 RPM and stays down...it's shuddering and making a roaring noise like a rearend isn't shimmed right, but not slipping and letting the engine wind up....am I making sense?

I KNOW the rearend is fine, as I JUST changed the fluid in it last weekend....No gear teeth, bearing parts or weapons of mass destruction fell out. There is no slop in the hubs, I just put both new hub seals in the rear end, and both sets of bearings were fine.

With that said, can I run this as a non-lockup converter? Like the C6's used to have. I know it builds heat, and I am ready to deal with that (got a big cooler...I mean a BIG cooler!!).

I am for sure doing the 5 speed swap, but I have to come up with the $1500 necessary to buy the parts and pieces needed to put the truck back together once I tear into it....this could take until spring with the way work is going....not good.

Any other quick fixes? I just need this to last a couple months....not 5 years.

So you put it in drive and locked tge converter right off the bat? If so, converter is toast. That's the one thing to not do.

You already know the converter is fried. Your best bet is to replace it before you loose the tranny too. The dollar meter rolls quickly when the E4OD fails.

The shudder is the clutch pack slipping. The converter could have warped steels or could have ballooned. Either way the converter time bomb is ticking.

I know that lol.... but if the converter was working to begin with...it should have stalled.

I am just waiting for it to do itself in so I can swap to 5 speed.

Shouldn't the RPM rise if it's slipping that bad?

for those who are reading this and have modded their torque convertor lockup to be on manual control, DO NOT ENGAGE THE LOCKUP BELOW 30MPH. What goofy is describing is the result of doing so. When the lockup commits suicide, all 150 sp inch of friction material and whatever teeth on the rings have torn off and is now circulating throughout your trans. no amount of chemicals will heal a sick torque converter outside of completely replacing it.

what where you "testing"?
if you just asked,im sure someone could have told you the results.
bummer!

Not always. The 90 in my sig is an example of that. That sucker would chatter (shudder) violently, but the RPM would drop normally.

When it it would chatter I drove it harder until it died. That sucker got so hot it had a burn ring on the cover. So much for a rebuilt stocker.

X 2 on this. Cleaning dead converter guts out of a tranny is not fun.

Well, as of right now I know that there is nothing in the fluid. I could be wrong, but I say this because the fluid is clear and clean as new. I knew the TC was on it's way out, if it's not already dead. I just wanted to see hwo dead it was. The E4OD is getting pulled in favor of a ZF, so even if I did blow it to hell this afternoon (which I doubt, it was dead before I got to it lol) I am not too concerned.

bummer!

A good converter should have killed the engine, it made NO change when I did it. I had nothing to lose...it was dead anyways. I just wanted to see how dead it really was.....it's dead.

That is good to know...I knew it was shot or on it's way to being quickly shot. So will it hurt to run around with it unlocked?

I'm listening...... you have my full and undivided attention. I can imagine UPS will be licking their chops when they see us making this deal! lol

 

[Goofyexponent]

Wait wait wait wait wait......I see what led you guys on wrong.

My truck was shuddering like a SOB on the way home. When I got home, I then put the truck in drive and locked the TC....nothing happened...no stalling, no movement.

I think you guys think I put it in gear, locked it, and THEN noticed the shuddering.....it was the other way around.

Sorry for any confusion.

You make me an offer on what you think is fair for the torque convertor, i will figure the shipping out and add it to your offer if you cant afford the shipping i will split it with you, i hate to see anyones truck dead

i dont think you will get a better deal, and like i said if for some reason this torque convertor aint no good i will give you your money back

 

[Goofyexponent]

I gotta talk it over with the missus when she gets home and see if we are gonna lay her up for the 5 speed, or stick a converter in it and run it until spring. I hate making offers David, I'd much rather you tell me what you want for it and I can write a cheque/certified cheque or however you would like the $$.
