SpeedFactory Racing is proud to present an exciting and much needed new product - the SF-Modified Shift Change Holder Assembly(SCHA) for B-series hydraulic transmissions!
　
1st off, what is the SCHA, and what does it do? The SCHA is located inside the transmission housing, and is the internal mechanism that actually moves the shift forks into position, engaging each gear as it is selected.
　
Why do you need this? Because you can't finish a race with a broken gearset or the inability to get it into gear due to a damaged SCHA. Because yours is wearing out and bending, and you want to get to it BEFORE it breaks and you ruin a transmission and gear set, especially if you're running a dogbox and big power. This also works great with stock transmissions and will help improve shifting, especially the 2-3 shift. Just push the shifter forward, and it will automatically drop into 3rd gear! It pulls the shifter to the center position with authority, to help eliminate the dreaded 1-2-1 or 2-3-2 mis-shift!
　
We've made improvements and fixed the parts that break so that you can make better and more consistent shifts, lower your ET's, and save your transmission! The SF-Modified SCHA is a vital component of a reliable transmission, and replacing it BEFORE it fails will save you money and frustration in the long run.



From Bullhead Gears:

We have seen a number of people experiencing problems with missed shifts and/or damaging expensive dogs and syncro teeth, and having difficulty finding the cause of these issues. SpeedFactory had experienced these issues as well in their Outlaw Civic while running the PPG Dogbox. In search of the cause and a solution, we shared the data we have been gathering regarding these issues from other racers across the U.S., and been working closely with SpeedFactory to identify the cause of these issues, find a solution, and implement it in the best way possible while keeping costs reasonable. Basically, this product was designed to address the serious need for a stronger, improved SCHA in these transmissions.

From SpeedFactory (TECHNICAL EXPLANATION):

"We here at SpeedFactory have spent many hours locating the cause of these issues when they occur in a properly assembled transmission through careful inspection and testing. The stock SCHA has been indentified as the source of these "mystery" issues in most cases. The problem areas of the stock SCHA have been identified and we have modified/replaced these parts accordingly, and tested this modified SCHA in our 950+whp Outlaw Civic with great success, as it has eliminated all issues that we had previously experienced.

The stock shift change arm is the biggest weak link. The stock arms are made of poor quality stamped steel, and are often damaged (stress cracked or bent). This piece has been replaced with a heavy-duty CNC machined tool steel arm that will not bend or break like it's stock counterpart. A damaged stock arm often goes unnoticed as the damage can be difficult to spot without disassembling the SCHA and/or checking for proper operation of the internal components through assembly and testing utilizing a windowed transmission case. Many people have damaged part after part and experienced issues shifting without realizing that a damaged shift change arm is to blame. Then, replacing it with another stock unit has resulted in the same problem occuring again, usually within a short period of time.

The interlock piece is highly prone to wear and bending as well, which negatively affects the operation of the SCHA and can result in increased difficulty shifting. This piece is replaced with a brand new oem part and braced, as well as bracing the SCHA itself to create a much stronger assembly that offers more precise, improved shift action and will hold up under the abuse seen during aggressive shifting such as when used in a drag racing application.

In addition to these modifications, the shift select return spring has been upgraded with a much higher tension unit. This gives the shifter a more positive feel, and returns the shifter to the center position with authority. This allows for much easier 2-3 shifts as well as greatly reducing the chances of the dreaded 1-2-1 or 2-3-2 mis-shift, and does not require solid engine mounts to work.

Saving even one missed shift, damage to a dog ring or gear, or reducing damage to a syncro sleeve or the dog teeth on the gear itself is worth it alone. Not to mention a lost race due to a transmission that doesn't want to or won't go into a gear because of a damaged SCHA. The easier 2-3 shift and reduced chance of a 1-2-1 or 2-3-2 mis-shift is a great benefit as well." - James Kempf, SpeedFactory
　
This upgraded assembly is great for those who want to make sure each shift engages as it should, especially under racing conditions, or for anyone desiring a better functioning gearbox with greatly improved reliability!

Pricing: $475.00
Note: If you have a core and want to send yours in to be modified, pricing is $375.00.

looks damn good guys keep up the good work

 

why so much for a little item?
I know it will save a lot of money over a new tranny but seems to price far out of reach for many tuners. I could see more people jumping on this if it was in the $175-200 range.



looks bad *** though...

 

What little item are you refering too?

We have many of the SCH this year and I would say 90% of the fastest B cars are running our piece. As stated in the description this is a serious issue with the transmissions that causes all kinds of issues if not addressed.

 

Bump!

 

Driving to Jersey bump....

 

I agree

 

In stock and ready to ship!

 

Up!

 

If it was less expensive to produce, it would be cheaper. The cost of the components alone is much more than $175-200, plus initial cost for R&D and production is ALOT. We aren't making a bunch of profit on these, just trying to provide a good product that addresses a known problem with the B-series transmissions.

 

 

damm good looking out..

 

high quality custom parts for extreme race applications don't sell for under $200. Nice looking product.

 

Thanks guys!

 

Bump!

 

are these modified brand new oem parts?

 

If you send in a core then we modify a portion of your used "Base". If you are purchasing a new unit then all of the parts are new that we use. The savings from sending in the core is the cost of the new base. Thanks and let me know if that answers your question.

 

Seahawks bump!

Still in stock and shipping everyday!

 

Man I'd like to have this setup

R&D, cost of production (yes, just of that little pivot arm), and assembly are all included in that "little item". Yes, it probably would sell quicker at that price, however, I would guess SpeedFactory are subbing the making of that pivot arm out to a third party - which charges them. Since there aren't 25,000+ of these being sold, SF don't have the luxury of economies of scale for production in the ways of CNC'ing that pivot arm unfortunately. Check the price for custom machining by a third party for yourself sometime.

Be proud of an American (modified) product that kicks ***! If I come to the point where I have an issue with the OEM one, I will gladly shell out this to support our own worker's time and hard work.
