I hated how the stock auto shifter isn't sporty looking at all. It looks like something that belongs in a Hyundai.


Its pretty funny that people who have the crappiest manual tranny Ford ever shipped (TR3650) are criticizing the great 4R70W
I would kill for a 4R70W in my Cobra, I really miss it (no I will not swap with you)

I tell you I would trade someone for a TR3650 any day of the week. I hate the auto.
jmod and trans cooler go in Monday and 4.10 gears are here just waiting to get an appointment.
The very fact that they want to trick people into thinking it's an auto tells you something.
Arent you supercharging you car and doing alot of other stuff to it too?
If so sell the 4.10s and get the 3.73s. Im swaping my 4.10s out next week will be shifting into OD if I don't.
Also who does your installs or do you do them your self?

The blower is already on, boost pipe, h pipe, plenum and tbody in the garage to finish it up. I am definatly going with 4.10s. I dont care about the track so I dont care where it shifts to OD. I just want it to be more fun to drive around town.
Honestly even with the t-trim making good power (325 through an auto with just a Bassani CB) I am not happy with it. It still feels really slow.
I would have went KB 2.1L if I did it all over, but I am not willing to start over.
As for installs, I had some 3.90s installed in an old 98 GT by Exotic Performance Plus and htye did an awesome job. Definatly going there for the gears again. I am having the cooler and jmod done at BC automotive outside of Indy. Supposedly the best guy for ford autos.
Brenspeed did the blower install, I tweeked the MPH tune on my own with my dynojet wideband.
you really do need to keep the revs down for the auto on the 1/4, you can't go into overdrive at WOT and w/ 4:10's and a blower it sounds like that's what you're looking at. You're going to be looking at a mangled stub/input shaftThe blower is already on, boost pipe, h pipe, plenum and tbody in the garage to finish it up. I am definatly going with 4.10s.

Im not going to the track with it so as I said I dont care if it would shift into OD running the 1/4.
It’s very hard on the transmission to be shifting into O/D at wide open throttle when you’ve added that kind of power on tap. Overdrive is applied via "band", not a set of clutches like the other forward gears…..so keep that in mind if the longevity of your transmission means anything to you.
