looks like a ratchet shifter ... which TCI makes one for our auto trannys i got one and love it. it works by a ratching motion with poistive stops so you dont slip into the next gear or reverse or nutrel on accident im not sure how to link videos on here but heres the link the the main company who makes them and if you search you tube for TCI Ratchet Shifter there are a few videos on there of it in use

If it is a 4r70w, that's what we had in our car (sold the 4r to 05mustang_KB about a month ago). The 4r we had was a full manual valve-body with transbrake and electronic overdrive. Pic of it in the car

Only has 3 forward race gears (electronic overdrive allows you to drive highway speeds without burning it up). You have to change gears like a manual but the clutch is gone. The little red button on top of shifter is the transbrake (used for reverse and dragstrip launches)

You won't see many 4rs on daily drivers. They are built to withstand wheelie launches at the strip and 1000+ hp. With a new street tune with 93 octane at high boost and the 4r, my mate went from a previous best of 11.8 to 10.3 @ 137 in the 1/4, the first time out with his new automatic transmission. He dropped an insane 1.5 seconds with his new street tune and 4r, and launching off idle (traction issues with Drs). He had no rollbars but now is faced with caging the thing, since the car is 9s capable.

We decided to go with a 2 speed powerglide (GM product), since our car is no longer street-driven.

i had a custom shifter on mine too..

Ackronberg · November 7th, 2009, 09:14 PM

so is the stock auto transmition the best or is there a better one out there its gonna be my dd but i sitll want a strong transmition.

06HellFireGT · November 8th, 2009, 01:03 AM

IIRC the stock tranny is good for about 600hp so unless your gonna build the motor and get blown you should be good with the stock tranny

Yeah, right.

06HellFireGT · November 8th, 2009, 01:33 AM

and i stand corrected

Anthony05GT · November 8th, 2009, 09:24 AM

I wouldn't push a stock auto past 400 hp.

UrbanRedneck · November 8th, 2009, 12:25 PM

That car in the video has a full manual valve body, so it doesn't shift itself anymore. If you want it like that, I don't know if they make manual vbs for the 5r55. And I doubt it'd be worth it to you to convert to a 4r70 on a street car.. But like anthony said, that trans may need to be beefed up once you have a blower.

forensicsteve · November 8th, 2009, 12:37 PM

This is a short in-car vid of Lance (driver mod) using the 4r70 at the strip. It's pretty old...not sure car was going 10s by then or not....but you can get an idea of the benefit of just 3 speeds (2 gear changes...you cannot miss a gear)

i do plan on boosting my gt some how not sure s/c or turbo yet so what would be the path i want to take. i was gonna get headers and cams or would tha be a waste of money

NastyStang113 · November 9th, 2009, 01:57 AM

First you need to figure out what you're going to do with the car and than make those choices.

Cams are going to need to be chosen per the application. If you're going to get a turbo than longtubes are kind of out of the question.

Ackronberg · November 9th, 2009, 02:01 AM

i have seen so much good things from both sides. if i would go s/c would be a roush but if i got turbo it would be the helion kit. still tring to decided what could i get done to the engine that wouldnr really affect the outcome but still make me perform better

NastyStang113 · November 9th, 2009, 02:03 AM

If you go turbo I wouldn't get the Hellion but that's just me. I'd get the Powerhouse kit.

Ackronberg · November 9th, 2009, 02:05 AM

powerhouse you say hmm gonna have to check them out. the stock auto tranny can take up to 500hp right

Ackronberg · November 9th, 2009, 02:12 AM

the powerhouse turbos i can seem to find any othere good system out there

NastyStang113 · November 9th, 2009, 02:21 AM

Here's their website.

I don't know about 500 rwhp. I'm sure there are plenty of people with 500 rwhp that have a stock transmission holding up fine. I bet there are a lot of people who have 500 rwhp and their stock transmission is losing 3rd. It's all about how you use it.
