Products & services

Actuator rebuilds are the core of our business, and we are continuously looking for new ways to improve these F1, E-Gear systems. The actuators, as with all our components, are not just a like for like rebuild, but are totally enhanced re-engineered units that have been vastly improved internally.


Modified Ferrari FF / GT4C Lusso PTU rebuild


As many of you would know, if you’re reading this, the PTU is prone to failure, which manifests itself in the form of losing hydraulic oil inside the gearbox – resulting in a mixture of the oils, and loss of hydraulic fluid levels. This is rapidly followed by a ‘4WD Failure and Manettino stuck in wet mode’, with an inherent loss of hydraulic power to the gearbox selectors inside the PTU. This is a joint venture between Martin Parkes and myself. Martin has a wealth of knowledge working on supercars, having over 22 year’s experience, working at main dealer levels and independents alike.

New stronger CNC machined aluminium end cap, replacing the old plastic one.


Actuator function check

SKU: SSA0-002

We will load your actuator onto our test rig and run a full health check. Testing for any leaks, mechanical damage, full range of motion, potentiometer readouts and selector finger position setting where applicable. Adjustments are made as necessary to ensure correct positioning. This check takes up to 2 hours to complete. Note, if your actuator is defective and a rebuild is agreed, the cost will be deducted from the build cost. If your actuator is good, this service gives you peace of mind to eliminate the actuator from any fault finding ecercise.


Power unit test and repair

SKU: SSA0-003

Full functional test of power unit. Testing includes the following: Motor function and condition. Accumulator system pressure holding.

For clear and precise operation of your cars E-Gear / F1 system, we here at ssautotech offer an unbeatable service and methodical diagnosis. Our mission is to keep your cars F1 / E-Gear system working as it should. Faultlessly. So you can enjoy your pride and joy as intended. Although these systems can be complex to work through, everything mechanical that brakes down, has a mechanical reason for braking down. We will find the reason behind the faults, and will be able to get you back on the road. We use only the best quality materials available, such as Norwegian tool steel, Nickel Bronze and Ti 6al4v, all commonly used within the aircraft industry, to give far superior strength over stock materials. We can offer upgraded enhanced parts across the F1, E-Gear system such as new pumps, sensor plates, end covers, Ti banjo bolts. All our componants are UK manufactured, using the finest quality materials, and OE sourced Magneti Marelli. We are also looking at offering stronger, lightweight hydraulic hoses, new sensors etc. We can make bespoke components per customer requirements. Please have a look at what we offer, and do not hesitate to get in touch if there is anything you would like made, repaired or modified. Thank You!


Just to let you know, the actuator you rebuilt for me is fitted and been working beautifully! Thanks so much! Emblem sports cars haven't seen a rebuilt actuator work so well.

I first contacted Simon after I saw an invoice from an Aston Martin owner who had his ASM system rebuilt and tested by him. It clearly showed that these otherwise unrepairable units were in fact fully serviceable and indeed upgradable. Considering the work that he has put into re-engineering and improving some of the components and from my correspondences I've had with him, it’s obvious that this type of work is passion as well as business. All in all, a very knowledgeable and nice chap to deal with


Simon has been involved with Selespeed since the early days and rebuilds actuators under the 'BHP' moniker. He was a real help to me when I wanted an in-depth insight into the internals of the F1 hardware.


As the owner of an original Aston Martin Vanquish (2001 – 2007) and a member of the AMOC forum, it was noted by members how expensive parts for the paddle shift manual transmission were, particularly the ASM actuator (c£9K!) Aston Martin would only replace items, not repair, so I tracked down Simon who has since carried out work on a couple of Vanquish’s, much to the owner’s satisfaction and for a fraction of the price quoted by the main dealer!

Although SS Auto Technology is a brand new site, we are not a new company. We have been repairing Magneti Marelli hydraulic actuators for Lamborghinis, Ferrari’s and Maserati’s since 2010.

We started diagnosing and repairing Selespeed systems for Alfa Romeo, and as such gathered a vast knowledge and understanding of how these systems work, and what they’re Achilles heals are. The Alfa system is not the same, but the principle of operation is. One of the features we offered was a re-engineered actuator, which had a bronze bearing machined into the housing – something which is not standard with the cast aluminium housing. This considerably helped overcome wear issues that original actuators suffered.

In 2010, A Lamborghini main dealer from North America contacted us to help with failing E-Gear systems. We took delivery of an actuator, and set out to find what the problems were, and what solutions we could provide. This took some time to figure out, but thorough examination and inspection of all components proved our theory. We have since re-designed the internals - as such they are fitted with new uprated selector shafts and bearings, as well as some uprated hydraulic seal sections, to vastly improve performance of these units!

We supplied a number of these repaired actuators, and overall performance was perfect. However, we did have a glitch with machining some of the new components and had to pull the plug until this was ironed out…. Due to the high accuracy and amount of processes required to achieve the specification we require, most machining companies just could not deliver. We have since worked very closely over the last few years with some very excellent engineering companies, and we now guarantee perfection with these parts!

We have also redesigned the expensive F1 / E-Gear pump units, and can provide brand new OEM equipment pumps at affordable prices! These units are identical to factory branded units, but as we were able to CNC machine new housings at affordable prices, we can offer these at great savings to you!


As the master technician here, I have a very sound engineering background, which started with an apprenticeship with the Royal Engineers. Time served, with over 6 years spent rebuilding, overhauling and testing hydraulic systems used across a wide range of applications. My specialised field was overhauling gearboxes, hydraulic control valves, pumps, PRV’s etc.
