Help with transmission noise diagnosis!
My transmission is a TCI Streetfighter TH350 with 1500-2200 stall with maybe 500 miles on both the converter and trans. My problem is when I shift to drive, there is a noticeable clunk as it goes into gear. As I then I release the brake and the car moving at idle speed, there is a loud banging or hammering type sound. As soon as I give some throttle the sound goes away. This noise only happens in DRIVE and in no other gears. It's almost as if the choppiness of the idle causes it to start, and only happens at when the car is creeping at idle rpm 900-1100rpm.
I have a new driveshaft/u-joints, no slop in the pinion, bolts on the converter are tight, SFI rated flywheel, it's a polyurethane trans mount, and motor mounts are in good shape. I've had the inspection cover off everything appears ok.
I can provide more info as needed, but I am hoping someone can at least get me headed in the right direction.Michael
