Description
Product update,
We have these 90% assembled but we did have one feature on the shaft fitting part out of tolerance for the TKO shifter and a design error on the base plate for TKX. Luckly these are both parts we just put in the box and ship immediately once they are ready.
If you want to place an order, we expect these to ship around the 21st of May 2024, if they are not shipped within a month of that we will refund at your request.
This shifter is to suit the TKO and TKX gearboxes and will your standard H-pattern gearbox to sequential operation with a simple bolt fitting for repeatable quick shifts. This has been designed for easy instaliation for anyone with basic mechanical skills. Get the next gear every time!
- ~ Precise mechanical feed back to the driver.
- ~ Fast consistent shifting.
- ~ Mechanical reverse lock out for safety and ease of installation.
- ~ Option of 0-5V position sensor for use with data logging and electronic dash equipment this can also be used for gear-based boost settings and other applications.
- ~ Optional gear indicator (sensor is now included in price of gear indicator, no need to select sensor separately)
- ~ Neutral can be selected between every gear.
Performance benefits
Get the next gear every time! It’s not possible to get the wrong gear with this shifter. No more accidental 2-5 shifts costing races or 5-2 costing engines.
Our sequential shifter does not work by forcing the gearbox into gear and will actually apply less force to the internals than a standard shifter and far less miss shifts will drastically reduce gearbox wear. The shifter has been specifically designed for use with synchro gearboxes and the loads encountered under hard driving, you will not break this shifter!
The shift speeds are improved purely through the greatly improved usability for the driver. The simple pull back to up shift and push forwards to down shift is much easier to coordinate all movements under racing loads than the H-pattern shift.

What’s included in this kit?
The basic kit includes everything you need to convert your gearbox to sequential shift including the shift knob but we do have some options.
Shifter Options
These options can be selected on this product page, please see gallery image on this page or click through to individual product for more details
- Gear indicator– Displays the current gear https://s1sequential.com/product/gear-indicator
- Gear position sensor– Senses gear position. 0-5V analog output and is needed for the position sensor to function of can be used with an aftermarket ecu or dash https://s1sequential.com/product/rotary-position-sensor
- Shifter Surround– This will cover the shifter and the hole in the transmission tunnel to minimise noise and fumes https://s1sequential.com/product/shifter-surround
- Offset lever– This is used to move the shift lever back or forwards , must have for vipers and Holden Commodores https://s1sequential.com/product/offset-lever
- High linkage lever– Moves the shift lever back or forwards and uses a high lever while maintaining short throw https://s1sequential.com/product/high-mount-sequential-lever
- Direct high lever– Moves the shift lever up and uses a linkage system to preserve the short throw https://s1sequential.com/product/direct-high-lever
(Dimensioned drawings are available for you to check compatibility, all shifters fit gearboxes and not specific cars, you may need to modify the transmission tunnel to suit.)
What is included?
The basic kit includes everything you need to convert your gearbox to sequential shift including the shift knob but we do have some options :
- The gear indicator and sensor can be used to display what gear you are in.
- The position sensor on its own can be used to display gear on many aftermarket displays.
- Shifter surround will help keep noise and fumes out of the car around the shifter opening.
- The high linkage lever will give you a high mount lever while maintaining the short thow and can move the lever backwards or forwards. This is mostly used for race cars and when the lever position needs to be moved further than about 70mm.
- The direct high lever will give a high shift position mounted directly to the shifter.

All direct mount shifters are design to fit the gearbox and not a specific car, with direct mount shifters most require some trimming of the transmission tunnel and we have the “shifter surround” part available to seal this back up. In most cars the shifter will clear the interior trims and look neat once installed, if you can’t find a picture of a shifter installed in your model of car send us a message.
TKO / TKX Special notes
To fit this shifter you will have to remove the rear housing as you have to with our R154 shifter , While its off you will also have to remove some aluminum from the case for clearance this could be done with a mill or with power tools, this modification will not prevent you using a standard h pattern shifter if you wanted to later.
These are available in right or left lever i expect that a lot of you will use the left lever in the cars these will be fitted too but please check picture carefully to understand.
