Hi my name is***** will be glad to help. Your likely cause is the pump front seal leaking into the transmission. Let me know if you need more help

Hi, It depends what system you have whether it is the two pump tandem system transmission driven or the single pump driven off the converter housing. Click on this link and see PDF page 15 for further explanation. since you have the converter driven pump let me dig into this further to verify all other components that would allow the hydraulic oil into the transmission. I will get back to you on this.

Expert:  Dan replied 1 year ago.

Hi, The transmission gets its supply oil from the charge pump mounted on the converter therefore sharing the same oil. the hydraulic pump is bolted and splined to the converter charge pump so your hydraulic pump seal is leaking into the converter and overfilling your transmission. Click this link and see PDF pages 30 and on.
