Welcome Penn Autos/Andy Frost race transmissions, home of one of the finest transmission builders in Europe.We're here to build you the best transmission that money can buy.We only use the very best parts available sourced from around the world!

We are exclusive UK and European dealers for Racetuf components and Hutch transmission parts. We are also dealers for Neal Chance racing converters, the finest racing converter on the planet! Call us for pricing on the weld or bolt together range that is in almost all of the world record holding cars in drag racing.
For the last couple of years we have also got involved in the Japanese race scene. These cars have a lot of power but have been hampered by the fragility of the transmissions they use. The customers we have installed and built transmissions for have ALL gone faster AND been much more reliable. 2014 saw our customers win championships,set PB's and have no trans issues!
If you need a trans conversion for 2015 avoid any disappointment and contact me now as we have a lot of cars already booked in and space will be at a premium very shortly...

We are now an official dealer for Gear Vendors under drive/overdrive units. These are the best way to have a higher HP overdrive and keep your strong 3 speed auto/4 speed manual transmission and not have the problems related to weaker 4 speed auto GM/Ford transmissions. We can also take the hassle out of choice of unit and also fit it for you if you require.

Of course we do more than high end racing transmissions.We cater for ALL typres of auto transmissions in everything from the 50's to the present day,from cars to motorhomes and everything in between. We have almost 30 years experience in the auto trade,which means we've seen and done a huge range of different transmissions.Of course If you can't remove your own transmission we're fully equipped to do the job for you.

We also cater for competent amateur trans builders. We understand that some people want to build their own transmission.Let us help you with HP DIY kits that we put together.Every kit is different so you'd need to call to discuss your requirements.We can also supply OEM parts for trans builds too!

We are also Pantera EFI dealers and started the revolution in using their coils in high HP applications over magnetos.  As well as being able to fire any forced induction or methanol application, they are also perfect for road use. We are more than happy to advise on the best products for your application, so give us a call.

Alongside transmissions we also do: Race engine builds,street engine builds,one off fabrication,steering,brakes and suspension upgrades,axle modifying and set up,and basic servicing.In fact if it's got 4 wheels we can do anything on it.
