4L60E-curing Torque Converter Shudder

[firecadet613]

Well my 95 4L60E thats mated to a 4.3 V6 has some torque converter shudder, anything I can/should do to cure it, fluid or addative wise? I dropped the pan two days ago, changed the filter and seal, added a drain plug to the pan, and refilled with Mobil 1 Synthetic ATF. After hearing it can cause this trans to slip, I drained via the drain plug and refilled with Supertech ATF just now, but the shudder is still there, just moves to different RPM ranges. Any good known fluid or addatives I should try?

 

Thanks,

 

Joe

Turn out to be my catayltic converter that had gone way south was sending a vibration up through the Y-pipe to the block and creating the weird noise, put a new cat on and all is good
