The pilot bushing leak is only applicable to the 722.6 transmission with its external TCU that needed a 13-pin connection. The 722.9 that your car has does not use this same busing. Its TCU is internal (in the conductor plate) and uses a simple, small 4-wire electrical connection to the car. it rarely leaks and if it does, it would not cause any issues except oil on the garage floor.

Does anyone know why the torque convertor would be acting up after replacing the valve body/conductor plate? The only thing I could imagine is not being programed correctly.

Sounds right, the TC takes it's command(s) for lock-up\unlock from the TCU.
The only other scenario I could see is the trans\converter is low on fluid.
Typically the converter is prefilled before it is installed. The final procedure is to road test the vehicle and then adjust the fluid level a second time as it will always lower.
It'd be odd if your shop didn't perform this last step though.

The TCC is very sensitive to changes in valve body and conductor plate. Usually any changes result in needing to readapt the TCC. It has been my experience that the TCC will never really adapt properly without the proper teach in procedures in Star.

Did you replace the valve body and conductor plate or just replace the plate?

Nick Louis

Yes I had both the valve body and conductor plate replaced.

dhurley

did a dealer do it or yourself? Was the trans readapted afterwards?

Nick Louis

I was fixed by a local Indy shop.

Nick Louis

When you say readapted do you programmed? Would that get programmed separate from the conductor plate?

Nick Louis

When you say readapted do you mean reprogramed? Does the torque convertor get programmed separately from the conductor plate?

dhurley

the conductor plate controls the torque converter. When replacing both the plate and valve body, the software within the plate has to match the software needed for the EHS# of the valve body. Im sure your indy did this.

After the plate is coded to your car, a teach in process (adaptation) has to be carried out with star diagnostic to make sure your trans learns the new fill times and pressures needed from the new valve body. This is done in three separate stages and can be done independently of eachother but generally should be done in this order:

1. Torque converter adaptation
2. Upshift adaptation
3. Downshift adaptation
