604 stripped splines

7/10/2008, TCRA Email Forum

I have a 2003, 604 10″ converter with stripped turbine splines. This unit has the hardened piston & t-hub with small o-ring & grooved lining on the cover. I know Sonnax has the turbine hub for this unit but I do not have it in stock. I would like to know if I can change the turbine & piston to the earlier design with larger o-ring & back-up ring, or will there be problems due to the design changes?

Thanks,
Rob Hans

You should be able to do that if you change the stator as wellJeff Stuck


Yes you can change the internal parts of a late model 604 to an earlyer model. I have done so many times without any problems. You must use the early model stator as well. jderrow1
