Drain and fill for me too only. It's easy as pie too....quicker than an oil change

 

Didnt have any symptoms b4 i got the flush. After around 500miles, I realized my reverse gear was slipping. My driveway is on a uphill and i couldnt reverse onto my driveway. On a level surface, I wouldnt have any problems going in reverse. But slowly my reverse got worse and worse. Eventrually I lost the entire reverse gear.

I complained to infiniti about the flush messing up my transmission. They said they would give me a discount for a new rebuild transmission from infiniti for 3500$. Im like forget it and left.

 

i will have to inspect mine, i wonder why a drain and flush messed it up? anyone have a clue why this would be bad rather than beneficial?
