UNLESS you take it to a shop that will open up the trans and get after the valve body- flush it, clean, refresh seals.
IMO when the AT fluid gets hot it thins (lower viscosity) and the transmission is then no longer is generating proper pressures to move actuators, etc around.
BMW dealers do not open transmissions...
Find a shop that can work on transmissions, that ONLY works on transmissions.
I cannot recommend this more strongly- I am convinced that we will see more and more E70 trans issues and we have little to no knowledge on how to fix these internals. (I will add that as a wife-driven car, who likely has never pressed on the skinny pedal hard enough to cause a downshift, **I** will not one of these trailblazers...  ) |
Ard - All of these are very good points. No Warranty left on the vehicle for it's at 53000. This is very weird issue for the fact that it does the same thing when engine at transmission are at operating temperature and at parked car you put the selector on D or R, it will do the same shuttering dropping the RPM's. Someone suggested it may be the clutch, but in this case the vehicle is at a dead stop. If you raise the RPM's to 1000 and then shift between D-N-R, the shuttering goes away. Dealer here investigated some vacuum leaks and said they found one and repaired it, so I'm more inclined to go that direction like davidmaria1 suggested.
I took the car to an indy shop and they were not sure what was going on, but were convinced it was not the tranny. I am thinking I need a 3rd opinion.
