I would love to hear more theories on what should actually be done when changing the oil/filter in both ZF and GM automatic gearboxes and also the recurring conversations of leaving high mileage transmission alone vs. diving in and rolling the dice.
One guy I would love to hear from the is automatic gearbox guru over in the UK (I always forget his name) but he knows his stuff. (RRPhil)?

I am currently doing our ZF 6hp19 in the e61 wagon. It has 186000+. Just barely starting to rough down shift under certain conditions. I already drained the fluid out so I am committed. I am doing the mechatronic seals (4 of them + bridge seal), mech sleeve, and of course new fluid. Hoping to find a cracked bridge seal or something as that will tell me for sure how much success I am going to have with the whole endeavor. Trying to avoid having to have the mechatronic rebuilt w/ new solenoids and internal seals. I will use the Foxwell for adaptations and resets of the trans. Will let you know how it goes OB.
After I finish with this one the wife's 6hp26 in her e70 is getting the same treatment with the addition of a rebuilt mechatronics unit. I'm hoping the complete service will avoid having to replace the E clutch bushing/bearing that goes out sometimes and causes pressure loss in higher gears. The symptom it is having is slipping out of gear and going into trans limp mode at highway speeds. Only done it 2 times 6 months apart, we parked it after the second occurrence so hopefully no trans rebuild is in our future. *fingers crossed*
