I am getting ready to yank my transmission out based on the noise diagnosis of ISB pending failure. I also have had another transmission issue since I purchased the car used 100,000 miles age (it had 150,000 miles on it then). It will pop out of 2nd gear if I release the gas pedal after accelerating hard in 2nd gear. This is rarely an issue the way I drive, but figured since the tranny will be out and apart... Anyway, I don't have any of the grinding noise issues I read of others having.
