old thread
I know this is an old thread but....
I have a similar issue
I just replaced the T-45 transmission on my Car w/ a used T-45 (mine was grinding going into any gear, even 1st or reverse from a dead stop!!). After I installed the used transmission (unkown miles but was pulled from a running car) and drove it around the block I heard a loud whining noise that sounded like the terminator superchargers in first, second and third gears (no noise in 4th or 5th gears). Its loud enough that my brother who was outside of the car heard it over the exhaust as I drove by (I have a Bassani X-pipe w/ high flow cats, magnaflows and dumps). It gets louder and faster as the revs increase in first, second and third gears. Has anyone had this noise...how bad is it (if at all)???
I can get into any gear (no grinding), my clutch feels great (only 20k miles on it, its a Centerforce Dual Friction Clutch)...
Other Info....
3.73 Gears in the Diff (same as before swap), Steeda Tri Axe Shifter (same one on previous transmission)....Also, I did not have this noise before swaping T-45's...so I do not think its the gears....
Any Clues?....Opinions?
