Tranny Howls in 5th

Ever since I installed the Pro 5.0 T-5 shifter with the positive stops the tranny occasionally howls like a mother on the highway at speed and temp. Almost sounds like a shift fork is rubbing. Sometimes moving the shift knob lessens the noise and it is only occasional. This makes no sense cuz its just a ball that slips in a socket on the trans. The stock shifter cures the problem but I shift pretty hard and you never miss 3rd with the Pro 5.0. and you gotta love the short throws. Anybody had this happen?

did you user RTV or some kind of sealer between the shifter base and the T5?

you *may* just not have as good a seal as you did before.

I don't know about the Pro 5.0, but the B&M Ripper has slotted mount holes so it can be mounted with a forward or rearward bias ... maybe if yours is like this, in an extreme position, it is too far in one direction for 5th gear?

You might also double check the adjustment of the stop bolts.
Sold my Turbocoupe. It went to a good home.

Thanks for responding guys. I did use the RTV and locktight and the throws were adjusted so there is still a little play so its not resting on the stop. The Pro 5.0 is machined such that it will only go on one way. Something just struck me though. If the ball of the shifter is a little longer than the stock one and is pushing down on the socket vertically, could that make the howling noise? I never thought to look at the depth. I'll have to check that the next time I have the console off. Right now it doesn't do it enough to pull it apart. Hasta
