Hello, First things first its a pleasure to be apart of your community of oil burners and I thank you for any help you may provide now and in the future.
With that said, as my title states i have a 97 powerstroke OBS with only 103,000 on the odometer, truck is mint and everthing that has ever needed to be done has been done immediately no questions asked, I am a technician with BMW so im very automotively inclined though auto trans are not my bread and butter. My situation is every once in a blue moon maybe once every two weeks i will have a very harsh engement along with a very loud metallic banging noise. Now this can happen at operating temperature or cold. I will come to a stop say for a red light and light turns green i come off the brake pedal and lean on teh gas, not hard, just driving miss daisy style and it will give me the loud bang noise. There is no delay assosciated with it and no slipping of the transmission either. Prediminantly I would check u-joints and pinion shafts however this is so intermittent that if something was loose I would antiscipate seeing it more frequently. Any help would be appreciated, thank you for your time and assistance.
Truck is a 1997 OBS powerstroke automatic E4OD 4 wheel drive. Truck is 95% stock. I have recently installed a 5 inch complete exhaust with a 3 inch downpipe, but to clerify this has been happening since before the exhaust was installed, and the prior exhaust was factory. Truck has no lift, no chips, trans fluid has been changed frequently and is currently clean as a whistle. No obvious u-joint play all front end components are tight with no play in steering wheel or otherwise.
