Before and After jmod ,2500 stall f150 0-60mph
This is my Before and After 0-60 build to my 4r70w tranny on my 2002 f-150 5.4l. It has all new frictions, plate seals, Jmod shift kit and 2400 B&M stall. Stock 3.55 gears were used for this video. Enjoy.
Post Jmod shift
Here's the 1-2 shift after the Jmod.
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)
