I've got a '94 4.0 Auto with a 3" or 3.5" Rusty's lift RE adj. trac bar and ZY TRE. I do NOT have an SYE or TC drop so there is a slight vibe when coasting. The other day I went to pass someone and hit WOT and at about 2500rpm there was a loud whirring sound (almost sounded pneumatic or like a turbine winding up. Needless to say it scared the crap out of me so I let of the gas. For the next mile or two whenever I would accelerate the entire truck would vibrate :shiver:. Now She's back to normal for no reason. Does anyone have any ideas what would cause this? I was thinking maybe a band in the tranny but she shifted fine and there was no loss of power.
