WCA Posted May 14, 2011 Report Share Posted May 14, 2011 what kind of auto trans does anyone recamend to swap out to? A 4R70W is your best choice. That way you still have overdrive for road trips. And with the auto you will run quicker and more consistant at the strip. Heres a link on how I did mine: www.westcentralauto.com/gt500_trans.htm Link to comment Share on other sites More sharing options...
flyvulcan Posted July 24, 2011 Report Share Posted July 24, 2011 OK, I'm a newbie so be gentle! I want to pick up a 2008 Shelby GT500 but it HAS to be auto (like I said, be gentle!). I've seen the mod that is suggested above. Would anyone care to comment on the potential suitability of the TCI 571000 Super StreetFighter Transmission (see http://www.jegs.com/i/TCI/890/571000/10002/-1?parentProductId=757655#moreDetails) and would I be looking at any extensive modifications (versus straightforward mods) to do this? Cheers, Dave Link to comment Share on other sites More sharing options...

flyvulcan Posted October 4, 2011 Report Share Posted October 4, 2011 I look forward to seeing what you have done. I picked up the Shelby I was looking at and now, I need to look at fulfilling the condition that my wife imposed on me in order to be able to get it!

1badshelby Posted October 13, 2011 Report Share Posted October 13, 2011 pinion bearing welded it's self to the pincion, so I had to rebuild the rear end... First test drive with the 4r70w today.... without the locking converter... smooth as silk, with the converter locked... look out. Taking it for test and tune friday night. I predict mid to low 6's in the eighth. Mike. Link to comment Share on other sites More sharing options...
Glenn Greenwell Posted October 14, 2011 Report Share Posted October 14, 2011 I dropped an e-mail to the FORD corporate offices the other day to ask if there were any plans to offer the GT500 with automatic. Got their response back today. "There are no plans to offer the GT500 with automatic". GG Link to comment Share on other sites More sharing options...
1badshelby Posted October 14, 2011 Report Share Posted October 14, 2011 The 4r70 fits really nice. Especially with the off road x pipe. I will post some pics real soon. Mike Link to comment Share on other sites More sharing options...

1badshelby Posted October 16, 2011 Report Share Posted October 16, 2011 the car picked up 1/2 second in the the eighth... track was not prepped, should have been even more. Can't wait to try it on a sticky track! Link to comment Share on other sites More sharing options...

frydguy79 Posted November 5, 2011 Report Share Posted November 5, 2011 i am doing a 2011 svt vert in the shop right now, it should be done next week, we went with a turn key set up from FB Transmissions complete with everything except fluids Link to comment Share on other sites More sharing options...
WCA Posted November 20, 2011 Report Share Posted November 20, 2011 Just a quick report for those interested. I have about 11000 mi on mine since I did the conversion to auto. It was the first mod I did to the car. I have to say I am extremely happy I did. Its still holding together and working perfectly. I run it hard every chance I get and go to the strip once in a while. Traction is the only problem I have now even with widened wheels and MT DR's.

SHELBYCS6 Posted November 22, 2011 Report Share Posted November 22, 2011 I broke the tremec and decided not to put it back in.... I'll get it repaired and store it, but on the strip this auto is INSANE! Mike Any reason you didn't look at th 5R55S transmission ?? I have this in my CS6 with the TCI ratchet shifter and it has been great. That`s the main reason I decided on auto for this build as it was the same tranny in the V6 as the GT had but the manual was much lighter in the V6 then the GT. I know when I have the GT-500 out for a long trip or in traffic I love nothing more than to get back in the CS6 and go for a nice enjoyable ride...after Woodward I almost needed a left leg amputation..lol BTW..the CS6 ran a 13.2 quarter with two passengers and a full tank of gas and still managed with the auto tranny to bark the tires on every shift.

It looks like we won't buy one for now. If we were to buy today, it would be an auto B302. Link to comment Share on other sites More sharing options...

The 4r70 is just a tougher tranny than the 55 in my opinion. Link to comment Share on other sites More sharing options...

I JUST got done with my install on a customers 2011 GT500 vert, i went with FB Performance Tansmissions,,, 800-769-1118, 4R70 complete kit, and other than not having cruise control no more, i see no problems with the kit,,,, until someone figures out how to make the 55r bullet proof, the 4r70 is the best choice.... one thing that needed changed out was the hard dipstick for a Lokar flexible one, which made a huge diff on the ease of the job Link to comment Share on other sites More sharing options...
