Well. Gillece rebuilt it thursday. i picked it up friday. and put the truck back together on Saturday.
Sunday drove it to a show, and on the way back it started whining, and grinding. Didnt drive it Monday. Yesterday i put it up on the lift, and its definietly the converter grinding. so its coming out, and i’m buying a new one. I dont wanna send metal through the Rossler.
The guy at Gillece said he never saw anything like my converter. Which scared me. And now its junk.
So its stopped permanently for now, till i get another converter.
Talked to the shop. He’ll work with me to fix it. He has a torque converter dyno in his shop. It cost extra to dyno a converter, so he didnt dyno mine. But this time he will. I told him the noise its making and his diagnosis is. 80% sure is a fluid “shearing” noise. He said that the manufacturer (TCS) used a high-stall pump, and to achieve a lower stall, the fins were bent on the pump. He said there was so much welding done on the pump side, that to try and rebuild the pump would’ve been timely and costly, and require extremely precise work. He did maintain precise tolerances when rebuilding mine though. Anyways, to achieve the high stall i wanted, he put in a different style stator. Now his diagnosis is that the fluid coming from the fins to the stator is entering at such an angle that the fluid has alot of deflection, and makes a shearing noise. He said that some early FWD GM converters did the same thing. He said if it was a bearing noise, i would’ve heard it in Park/Neutral. Besides, the bearings are brand new.
Anyways, i’ll pull it out, and he’ll dyno it to try and recreate the noise. If it is fluid, he’ll run a different style stator to quiet it down.
due to the cough loudness of my truck, diagnosing it while its in the truck is out of the question. so i’m gonna pull it.
Jim will get it right for you. He really knows what he’s talking about. He built mine back in 01 and had it apart in 02 when my transmission grenaded. Right now it has somewhere around 850 passes on it, with no troubles.
