Hello eveyone...I am relatively new at this...am the proud owner of an Audi with AT but am having some concerns about what I heard once being called a "drag brake" effect... It seems that when going from accelerator to brake immediately there is a hesitation in the transmission in releasing the gear...motor boggs down a bit and then everything is fine. Could that possibly be due to a bad TPS or something like that? Have tranny services every 10k.
