I have a 97 F250 OBS
power stroke 4X4 crew cab and i have searched the net and this forum and cant find anything on the noise im hearing, I just had my transmission rebuilt everything new with a huge cooler and even installed a diesel site transmission filter :thumbsup:. A week after it was installed i was coming up to a stop light and while hitting the brakes and slowing down it made a sound like a bearing was going out. the noise comes from the front of the transmission right by my 4X4 shifter in the cab and once the truck stops it goes away but it will do it in reverse if i try backing up hard to :icon_mad:. it has been getting worse by the day and now does it sometimes when letting off the throttle when doing around 35 mph. Also it only does it when the truck is fully warmed up never when its cold. at the same time as the transmission rebuild i had a fuel bowl deleate system installed with a pre and a post electric super duty pump filters and i thought it might have been the motor was not getting enough fuel but my fuel psi is 65 to 70 psi and the truck runs great cold just not warmed up. lately it starting to sound like the transmission bearing noise is slowing down the motor when coming to a stop or something weird like that. it very frustrating any help or ideas please.
