Glen McCartney rebuilds 928S tranny.

 

So yesterday I watch the Jay Leno video about the new Jag F type and they talk about their new 8 speed auto tran that has really quick shifts, 0-60 4.2 sec, and I wonder about it. What really is an auto tran, what goes on? It seems it's all bout the Torque Converter. So what happens inside the torque coverter. Lots of Voodoo! I watched youtube video's, still its tough to grasp. Some coincidence that this thread pops up.

see the tc here - http://www.floridatorqueconverters.c...ons-722-3.html

and here - http://www.gopnh.com/Transmissions.c...ssion=%20722.3

and I was wondering Has anyone here ever opened up one of our torque converters?

All TC's have an impeller, turbine, and stator, with some having a friction plate clutch thing that works as an overdrive. I don't think we have that. (I cant find a parts diagram that opens up our TC) The TC is a torque multiplier at take-off. The reason my particular 928 Euro is so fast is because of the optional A.28.06 tranny and in particular the TC. The Voodoo is strong in mine. So if your 928 auto is not quick, many things to look at, engine, linkages, but especially what tranny and what TC in that tranny and how is it functioning.

I need to watch more of these

 

I've tried to instigate some interest in tighter/higher stall torque converters in a couple threads. Would be a terrific upgrade. In the spec books, you can look across the various calibrations for stock units.

Any chance you guys could title your helpful posts for the benefit of posterity? TIA

 

My shifter does not line up exactly with the letters on the plastic console.
How can I adjust?

This may help some, I think the most important one is the big O-ring that goes around the oil pump, they seem to get dry/brittle and then crack.
