  Welcome to Ashcroft Transmissions Online



Ian Ashcroft 1942 - 2021





It is with a very heavy heart that we have to announce that Ian Ashcroft sadly passed away, unexpectedly, on Friday 25th June.



Ian Ashcroft was the founder of Ashcroft Transmissions Limited, formerly Automatic Conversions, over 30 years ago. After completing an apprenticeship and degree in Mechanical Engineering, Ian spent 20 years in the manufacturing industry. He worked in various capacities, including maintenance and design, where he has gained a wealth of experience. Automatic Conversions was born as a quest for a reliable transmission after successfully destroying endless Series II & III gearboxes with a V8 engine.


Other developments followed in an attempt to further improve reliability of the drive train. He had considerable technical knowledge, which he has demonstrated in the design of many of our products. 


Ian had retired to Spain 10 years ago but returned back to England at the start of the pandemic.  During his retirement he still offered advice and remained interested in the success of the Company and any new products that were being launched.



He was so well regarded by his family, friends and ex-colleagues and will be very dearly missed by all.




Sorry but our lead time on all transmission builds is currently around 5-6 weeks. We are sorry we cannot be more precise at this present time but staffing issues related to Covid 19 means it is very hard to schedule work more accurately. We are doing our very best to dispatch all orders as soon as we can.



Please note that our shippers have temporarily withdrawn the economy service to Australia, New Zealand, China, Canada the USA and other far eastern countries.  At checkout please select the express service.  If this is not done it may be that your shipment will be subject to additional shipping costs.  If this is the case we will advise on receipt of your order.  Sorry for this inconvenience but this is beyond our control.



We are a UK based company solely specialising in the supply of rebuilt manual and automatic gearboxes, transfer cases and differentials to suit Land Rover, Range Rover, Discovery and Freelander 4x4 vehicles.
Rebuilding transmissions is our core business but we also supply other related products such as gearing changes, heavy duty axle components, locking diffs and Defender automatic conversion kits to name a few. We have listed most of our product range but it is impossible to detail everything.
The site sections cover most of our products but often an enquiry will sometimes overlap 2 or 3 sections. If this is the case, please give the vehicle specification and intended use so we can offer the best advise and quote correctly. If your enquiry relates to a Rover 4 x 4 and you cannot find the answer on our site please phone, fax or email us at
Whilst we usually aim to dispatch transmissions units usually within 5 working days of any order being placed at very busy times and the lead time may be longer and will be advised above.  Many part orders can be dispatched within 1-2 days of ordering for overnight delivery within the UK.   Carriage prices will show once the order is placed in your basket and you have advised your shipping address.   Payments can be made securely via Sagepay, Paypal or bank transfer.  

Please note that the prices shown in this website, unless otherwise indicated, do not include VAT.
