4.6 and Auto Trans

[acdrew]

How many of you guys run automatics behind your cars and how do you like them behind the 4.6 motors. I have one on my nova and run a floor shifter. I was thinking of doing a setup like this on the cobra eventually. My main concern is how will it react to the high winding mod motor. The pro's I see are consistent times at the track and affordability. The cons I see are possible daily driving issues with a decent stall. I don't see paid 2000 for a used t-56 that has been beat on or 4,000 for a brand new setup and I have heard the TKO transmissions don't like the rpm range of the 4.6 motor.

I love my 4r70w, Its so nice to just hit the lock up & OD switch.

i have one, enoy it a great deal... sometimes i do wish i woulda just swapped the 5speed as well. only downfall to having an auto to me, (could be the trans tune) is the shifting around town vs. WOT....

Another fan of the 4R70W here. Even with as much as a 4K stall, a quality lockup TC will perform well in a DD application. Shift/lockup schedules, pressures, etc are all adjustable in the tune, assuming you use a compatible EEC.
