The fluid is compatible I think..but the problem is that we mistake when we empty the torque converter..this is the first time we empty to TC ..do u think 8 liters is not enough..?

Dont think. Do post what fluid was used.

There is no way to empty the torque converter.

If you correctly checked the ATF level, the number of quarts means nothing

Don’t remember what brand of fluid I was used .. but he didn’t touch the torque converter , he just unscrew the plug and let the fluid drain out. But this time he empty the TC so the problem appears..

Well, the Lubex website i glanced at didnt list a full synthetic low viscosity ATF with Asian compatibility.
They list a bunch of DexronII/III equivalents which will destroy your transmission. That "concussion" is your transmission about to die.

Its only a $7000us transmission and only a Jinn would use unknown ATF and complain about concussions.

Buy 16 quarts of Toyota-WS transmission fluid and perform a cooler line fluid exchange, 12 quarts pumps thru the ATF cooler, and save the last gallon for the transmission pan. Drop the AT pan, replace the filter with genuine Toyota ATF filter/oring/gasket, clean the magnets, and refill with final gallon of WS fluid. Check ATF level using an OBD scanner for proper ATF temp for proper overflow level check of the built-in removal pan straw.

Plenty of youtube videos and threads online that cover the u660(V6), and u760(4cyl), flushes, fluid level checks....

Shudder fix is a bandaid for bad or wrong fluid

If it was my car, I would try replacing two quarts at a time with WS fluid, to get back to original spec.

The incorrect fluid apparently was not sufficiently replaced before the Shudder Fix was added.

I would not want any more Shudder Fix friction-modifier additive in my transmission than proved to be absolutely necessary, so I would back-track toward 100% WS fluid (two quarts at a time) to see how much original fluid spec can be restored without symptoms. The additional flushing can only be good for your transmission's service life!
