Is the automatic street/strip kit the same as the automatic valve body Hey, I just had a question wondering what is the difference between the street/strip automatic valve body kit and the street/strip shift kit. Would I need to buy just one or am I able to buy both and install them. Thanks and hopefully this isn't too dumb of a question.

Will this work on an '04 GT? I understand the 4R75W is excluded, but several reviews are from '04 GT owners. I thought all '04s had the 4R75W. If this is not the case, how can I determine if I have a 4R75W v. 4R70W?

Will this fit a 4R75w, or simply not work as well? I have an 04 GT and would like to install this, but not sure if 1) I absolutely have a 4R75w vs 4R70w - how can I tell. No reliable info out there; and 2) will it still fit if it's a 75, but not work as well? Several reviewers have 04 GTs so I am confused.

  • Look at your VIN, then run it through a VIN decoder (just Google one). Your transmission type is in the numbers.

    Well worth the money!

    Put this in with a Trans cooler and a deep sump trans pan. Plan for a messy install...and be sure to re-torque the bolts a few days after install. My 03 GT, with ZERO other drivetrain mods, chirps the tires when it hits second all the time. (Be careful not to misplace the included springs..tossed mine by accident!!) HIIGHLY recommend this mod.

    Amazing Buy

    One of the best purchases for an automatic. The car shifts fast and hard and makes an amazing difference in acceleration and take off time. Chirps my tires going into second and third, if you have the time and patience to install this it is well worth it.

    2001 Mustang Gt Convertible

    This is a great product that every mustang owner should consider! Specially if you've upgraded to 410 gears as i did. All i could say is "wow", my car feels much more powerfull when it shifts and even chirps the tires. Only wish Performance Automatics would've included some instructions, diagram or something to save some time. Other than that it's a great product! Thank you American Muscle!

    Big improvement over stock

    Had this installed by a transmission shop that was highly recommended by more than one person I asked who they would trust to do the job. The shop has done "dozens" of shift improvment kits. I paid the extra for synthetic fluid, and the car already had a transmission cooler installed after the radiator cooler. I'm very slightly disappointed. After reading the reviews here I expected some neck-snapping tire-chirping hard-hitting shifts, especially the 1-2. Yes my 04 is a V6 and I am taking into account it doesn't have the power to blast the tires loose when I feel like it. Although the kit did significantly improve the shifting over the mush-box that was stock from Ford, I didn't get those head-banging shifts. They are firm and tight, and happen a LOT faster than stock. The car is much more pleasant to drive now, and that two second "which gear do I really want to be in" that was so embarrassing is gone. I'm (by a great majority) pleased with the results, and definitely happy I bought it. That tiny disappointment is there though. Just keep in mind, you're results may vary from what other reviews say, as mine did.

    The only shift kit I could find for this transmission

    The instructions are very limited if you have not done this mod before. The instructions assume that you already have the valve body out of the transmission and laying on the bench. They also assume that you have prior knowledge of the internal components of an automatic transmission. Like where is the 1-2 accumulator piston ? This is a great kit but instructions are not for the beginner. Also, for the price a few drill bits should be provided.

    Shift Kit 2003 V6

    It took all day but overall not bad. The trans fluid mess was the worse thing. Dropped 11 qts during the change. Most likely I had some of the cooler drain back. The shift change was not major, but I put in a Bama tune a few days later and that made a huge difference. so recommend doing both at the same time.
