For those with a '97 or earlier 4R70W should replace the outdated 1-2
2001 Ford Crown Victoria police interceptor Jmod 0-70
2001 CVPI After doing Jmod to the 4R70W transmission. im submiting this
video of what the results and gains were from it im not 100% sure but it
looks to me like i began accelerating at 0:51 and reached 70mph at 1:01 so
0-70 in 10 seconds maybe. not Super fast but works for me.
2003 Crown Victoria 0-120
Half throttle chrip, followed by 0-120, followed by a 2nd gear 50-80 pull.
2nd Cat delete, glasspacks tune and jmod

Magnaflows are inside.
JMOD 2004 Mercury Grand Marquis LS (part1/2)
Just installed the jmod on my car this weekend and am very pleased with the
results! I left the accumulator springs in so the shifts feel more like a
snap of the finger rather then a punch. I think the shift responce is the
same either way. Leaving the springs in seems to be easier on the
transmission. (This video is driving through the subdivision)
Mark VIII attitude
A video stitched together of a few different shots that I have taken of the
Mark VIII in action. It's an attitude video. Some pretty good burnouts
and great rolling shots, if you are a fan of Mark VIIIs
1998 Mustang GT J-mod
Just showing the shifts in a J-modded (Jerry modded) 98 GT. Car is
supercharged making 325 rwhp. Car shifts SO much better after the j-mod,
should have come like this from the factory.
