5 Top Rated Questions

How does this work coupled with a Bama or similar tune? Does a shift kit do basically the same thing regarding shift points and firmness as a custom tune, or are these coupled together even better.

This Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) is going to make physical changes to your transmission to help firm up shift points, strengthen your transmission, and help bring shift times down. This kit paired with a custom tune will bring a much larger benefit than just one of them alone.

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.

Well, they are kind of one in the same. The Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) is what you would purchase if you were interested in taking your current valve body and replacing the innards with this upgraded shift kit. However, if you needed and brand new valve body, it would come already upgraded.

Helpful (4)

Is putting a improved shift kit in a transmission with 124k miles a good idea or do you recommend rebuilding it first?

Depending on use and maintenance, the Performance Automatic Street/Strip Shift Kit should be fine in your transmission, however we recommend having a shop check the transmission over to make sure it is in good condition.

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.

From what I understand, the 75 is the same thing as the 70. Some late 2003's got the 75 and all 2004's got the 75, but the late 2003 and early 2004's got all the 75 without the extra sensor (OSS) and the mid-to-late 2004's got the extra sensor. The 75 is simply the 70 with beefed-up in internals (namely a 24-spline shaft vs the 6 spline of the 70). This is what I've gathered as I've been looking around for rebuilds and torque converters for my transmission.
Look at your VIN, then run it through a VIN decoder (just Google one). Your transmission type is in the numbers.
04 came with the 4r70w on the v6 and v8 so yes this will work well

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?

The Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) definitely works for 04 GTs.

will this work better with stock gears or 3:73s Like is it meant for stock or aftermarket 1 answer

Do you have trouble taking off if you aren't completely stopped? For Instance if you are approaching a red light and right when your about to stop the light turns green, when you hit the gas will it go or will you have to stop completely and then take off? The reason I ask this... http://www.americanmuscle.com/performance-automatic-valvebody-9604.html Read the review to the previous link. I know that is for a V8 but I wanted to know if it is having the same effect on the V6. 3 answers

No you should not have trouble taking off..Unless you have transmission issues..Shift kit just controls your shift firmness and so on..It also makes your transmission make a lot nicer and cleaner shifts..
I installed the shift kit in my 2004 GT and never had any issues to where i needed to come to a complete stop. I find it actually helps out some, doesn't search for the gear as much.
I installed it in my 04 V6 and I haven't had that problem at all... It just kicks ultra hard in second :)! So no, it's not like that. It's better.

How does this shift kit compare to the J-mod? It this just a cheat allowing you not to have to drill out you plates? 1 answer

Hello! The Performance Automatic Street/Strip Shift Kit is designed to perform in the same way as the J Mod, but without the worry of having to drill out your valve body plates yourself.

Does this go on an automatic transmission? 1 answer

Yes, this is specifically designed for an automatic transmission.

Is this technically a JMOD kit then? 1 answer

The Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) can be considered a JMOD because the channels will be slightly bigger so that fluid can flow better. This kit also comes with 7 replacement springs.

Is this ok to put into a daily driver, or will it hurt the transmission rather than help it? 1 answer

You can install the Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) on a daily driver. This Shift Kit will not hurt the transmission. It will actually improve your driving experience while eliminating shift overlap which can cause unnecessary wear.

Helpful (0)

When installing the Performance Automatic Street/Strip Shift Kit (01-04 GT, V6, Mach 1) you should not noticed major increases in your transmission temperature. There is no need to purchase a deep transmission pan either.

Rubber in 2nd gear

This kit gave my v-6 Mustang a good solid hard shift when really getting on it, squawking the tires when you hit 2nd. Couldn't be happier with the performance of this shift kit.

Well let's start by saying when I received this kit it came wit no instructions, so I contacted AM and they say they don't have them and to contact the manufacture, so I did, still no instructions, so after digging on the internet I find similar instructions then come to find none of the springs in the kit I received fit my transmission. And yes I have a stock 4r70w trans that's now disassembled thanks to AM

Greatest product for your Mustang!

First of all, AM shipping is outstanding! I ordered it on a Wednesday and got it that Friday! Amazing! I had it put in a few days after I purchased it and I can definitely feel the difference! I paired it with a BandM ratchet shifter and it makes my automatic feel like a whole new car! Nice, tire chirping, firm shifts! Definitely would recommend if you want to have fun in your automatic GT! Thanks AM!

Worth it when coupled with other things...

My transmission was rough shifting and seemed to be sticking solenoids, so i figured time to change them (195K mi). I figured while i was under there would be a perfect time to install this shift kit. It seemed overwhelmingly complicated at first but I (who am not a trans person) was able to work my way through it. This kit coupled with new solenoids, 2 bottles of Lucas stop slip, fresh Castrol Mercon V and Trans filter has brought a fresh breath of life back into my transmission!! It operates so smoothly now, it hard shifts because of the kit but its a smooth hard-shift not one that feels like doom for your trans. I would highly recommend to anyone with a 4R70W transmission this kit and service the filter and solenoids (if high millage) and definitely some Lucas!

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.

I installed on my 2003 mach 1 and really have not felt a difference. Instructions were not good so took a little longer than it should have. I wasn't the original owner of this car or know who ones it before so don't know if there was a kit installed before I installed it.
