Trans Issue Diagnosed - At Last!
Friday, April 22, 2011 at 4:43PM After much head scratching and the complete disassembly of the transmission (it was "like new inside), I sent these photos to Michael at MV Automatics in Australia . . . because the only thing we could think of was that the torque converter had failed.
These are the splines inside of the torque converter.
These are the transmission input shaft splines.
This is Michael's reply:
"I've just seen [the photos] today. Whats actually happened, the imput shaft splines are intact but the hub has torn out of the front turbine. The steel hub is riveted into a press steel turbine. You can see a small amount of damage on the end of the input shaft where the clutch seal runs. The converter has to be cut open to be repaired."
I may have caused this . . . . or just too many hard runs. Either way, I am glad to know what happened. So, what to do?I have access to a 4000 stall speed converter for a 1UZ (not a 1JZ converter like I now use). I will change the front pump on my existing race-built transmission from the 1JZ to the 1UZ pump, which will index everything correctly and eliminate the need for the drive ring. Wish me luck.
