Now Im just waiting on the pillar pod and getting a decent gauge and it can be installed!!!

 

My 08 2wd driveshaft is aluminum. Should net be an issue with 4.56 gears. It is a popular upgrade for Mustangs to upgrade to an aluminum driveshaft. Perhaps if off-roading and you drive over something and hit it, it may bend easier, but in normal conditions, no problems.
Also, a good shift kit will reduce actual shift times which will increase acceleration a little bit as well as reduce slippage between gears which increases transmission life.

 

bringing this back from the dead so we can all learn a little from this great info.

and also, what would a higher stall TC do in towing situations?

Assuming you didn't up the stall too much it would help you take off from a standstill easier because it will bring your truck right into the meat of the torque curve. Go to high with the stall your gonna burn up fluid and sit there and rev which is gonna suck. IMO in a towing setup I would run an upgraded converter with maybe 100 or 200 rpm more stall speed at the most or a stock stall speed to get you the most gain for the application. This is what I plan on doing.

 

me too

 

Not to sure that one would be true unless you are going super high with the stall, in other words 3000+. Regardless you wont sit there and rev. My TC is right around a 2700 stall but it will start to move between 1200 and 1300rpms. About 2 weeks back I had to help a friend move (damn friends with tiny cars) so I borrowed my dads utility trailer (about 5'x12' +/-) and loaded it with all the big stuff, floor to ceiling cabinets, full pool table, couches, bed etc. Dont know exactly how much it weighed but I do know the slate from that pool table took 5 people to move. Anyways the truck drove just fine, still moved well before the stall kicked in right around 1500rpms.

 

hemiguy is right. A higher stall will cause excessive heat in towing situations. I've talked with Andre from Edge and he doesn't recommend going higher than a 2600 for towing. You may be fine for a quick trip, but you get stuck in stop and go traffic and your tranny can heat up fast.

 

Thats why you also need to get a larger trans cooler along with the converter.

 

A trans cooler doesn't help in stop and go traffic.

1. There is not enough airflow across the cooler.
2. If the vehicle isn't moving, the trans isn't pumping fluid through the cooler.

I wish it were otherwise, but it is the reality. People that tow occasionally may be OK, but for folks that tow regularly, high stall tc is a big no no.
