Well, think its about 9 months worth of solid abuse on my BTO level 3 2004r. Recently I noticed that under manual downshifting, for compression breaking, it seems as though it's not working as it used to. It's coming back to idle and not slowing the car down. Its in gear though, as I can rev the motor back up and it will rev to the point where it matches speed and accelerate. It shifts fine, drives fine, doesn't make any odd noises, kicksdown as it always has and shifts with authority. If I keep it in manual 1st or 2nd or 3rd or whatever, and bring the revs up to 3000or so and let off teh gas, it does compression brake till the revs fall to 1600RPM where it goes back to freewheeling. Did I blow out a seal or a gasket or something and the tranny is bleeding off pressure internally? Called BTO today and talked to them, they said that below 1600 the converter isn't really building any kind of pressure and things are normal? Maybe I'm just trippin'. Input? 2400stall, mild Pontiac 400.
