Hey I have a 2003 p71 and the trans went in it. If I get a trans out of a 2003 Mustang GT which has a 4r70w automatic trans will that be a direct bolt in or will I have to change electronic components. Pretty much what I am getting at is what do I have to do to get a mustang trans to work in my crown vic

I would check the Haynes or Mgf Service manuals for both vehicles for compatibility.
....maybe check you local library if you don't yet have your 2003 cr vic repair manuals...

I believe that all 4R70W use the same wiring setup until 1998. But check with a local trans shop to check it out.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter

.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos
