Got under the truck tonight and unbolted the flexplate from the torque converter. TC bolts were still good and tight, the flexplate tight to the crank and rings like a bell. Sure its not cracked. Anyway threw the starter back in and fired it up. No noise. Has to be the torque converter. Guess it could be the tranny but don&#39;t think so from the location of the sound. At least it isn&#39;t the engine. The verter is going back to PI for a fix.

Anyway Chuck at FLT called, the built tranny shipped yesterday. I at least see a finish line ahead.

My LT1 TA had a noise like that , it would come and go. It took us for ever to fig. out where it was coming from. I had a bran new conveter and tranny. The car pulled great. One day when I had it on the lift running, I heard the sound coming from the converter. I sold the car over 7mths ago to the guy next door. Still makes the noise and still runs great. O-well. Who now&#39;s?

Just for safety&#39;s sake, remove and inspect the flywheel when you change the transmission so as to verify 100% that there are no cracks in the center area particularly between bolt holes.

New TCI flexplate in the garage going in. Much stronger unit.

That is a good idea. Plus it gives you peace of mind with the extra power.

Yeah it started off fairly mild. I could have seen me driving it like that for months. It got much worse though. Still drove fine, or at least for the last few miles it took me to get home after I started hearing it in the cab.

I had a 88 1 ton with a 454 and TH400. One day I started hearing Armageddon coming from underneath. Put the truck in the air and found the flywheel was cracked all the way around where it bolted to the crank, and the TC had 2 ears knocked off. In addition, some of the gear teeth ring were gone. I had to replace the TC, flywheel and front seal on the tranny, and put a new oil pump in for grins. Sometimes, you really cant see the cracks on the flywheel and its cheap enough to replace. I would also check the mounting tabs for the TC, they could have a crack as well. After replacing mine, problem was solved.

Haven&#39;t got the flexplate off yet but looking at it on the engine it is fine. No matter, putting on the TCI tomorrow.



Got the tranny out. Getting pretty good at it, this is the 3rd time I&#39;ve had it out. Getting to old for this. Did find the best way to manage the transfer case, to hell with jacks. Can you say grab the sucker and bench press it out&#33;

Yes it is a lot of work. Hopefully the last time I do this for awhile. Floor is an Epoxy by Rust-Oleum. It is tough&#33;

cool ,me likey&#33;&#33; got to get that, thanks for the link.

what are your thoughts on using synthetic trans fluid in the tranny and trans case? is it worth it or is it too slippery for the trans?

No problem on the link. everytime I post a pic of my garage floor someone asks about the floor.

I&#39;m going with straight Dexron III tranny fluid. GM uses a synthetic in the transfer case. Called "AutoTrak" fluid and that&#39;s what I&#39;ve used to top the transfer case off after the installs. I think synthetics are great for diffs, transfer cases, and the engine. Not so good for the clutchs in trannies.
