Quick question for 99-04 GT auto trans guys
#12
o/r h mac prochamber and super 40 series american thunder. the noise started coming when i first put 4.10 gears in, but I had forgotten that I put a catback flowmaster american thunder in. So it may be the exhaust. I've resorted to putting 3.27s back in since there was so many problems getting it tuned correctly.

Would there be any increase of wear on the trans if I choose to leave o/d off until I'm getting on the highway? I would hope that if I use it appropriately that I won't end up making things worse. Past experience has shown me that when I start messing with electrical functions, things go bad quickly. But that's my mistake for letting the wife talk me out of getting a manual...

Either way, it sounds more of a mechanical transmission issue by your description. The torque converter doesn't seem like it wants to completely lock at O/D. This is what could throw your rpms off as well.
Hope this helps!

did you install the metal exhaust gasket/spacer on the pass. side between the manifold and the h-pipe? Nothing really hurting if leaving OD off until you get up to speed, but not necessary to leave it off until real hwy speeds. Just turn it on 45/50 or so if your not trying to accelerate hard. OD isn't just a converter lock-up. You should feel the converter lock-up with the OD turned off even in 3rd gear under easy acceleration, the rpms will drop a few hundred as if it's going into another gear.

Whens the last time the fluid was changed or a service done on that tranny?

Naw, like it's been said by a few people, its actually best that you don't use O/D in normal driving. You may see a slight loss in your mpg, but it'll be better for you in the long run. Save the transmission until you can afford to get a new one.

Yeah see that's exactly what I thought, that I used to do 1800 at 65mph because I don't remember my needle touching 2k rpm when I was going 65. But currently I'm doing 2k rpm at 65mph so I wonder if the 3.27 gears I got from Ford Racing have different dimensions than the stock 3.27? Which would seem strange
