Hi. Chuckles here. I have installed a 2005 P-71 engine into a 1957 Ranchero that has it's original manual transmission. The P-71 was an automatic trans. My PCM is 5W7A-ADA. What suffix code do I need for a manual programmed PCM?

I'm not exactly sure, but I believe the 2005 manual trans Mustangs used PCM 4 digit code is CDC3. I think you can buy a rebuilt PCM for about $175

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

Thanks. I will look into this. Will the Mustang PCM accept the three plugs like the Crown Vic? And are the "pin outs" the same. Chuckles
