A little something else we have kept under the radar…. The team at Gilroy’s Race Transmissions officially has a test car!! This LS Turbo HQ paired with a transbraked TH400 is now ready to view the strip at the golebysparts JZ Fest this Sunday March 24.

711 HP at 13 psi.

We will get some data with the TH400 before putting an 8HP in it.

We would like to thank Madoc Tuning, wirelab, hipower_performance and the team and workshop Goleby's Parts for getting the final touches done.

A little something we have been keeping under the radar… until now. A good mate of ours has been manufacturing these 8HP billet bellhousings and front pump set up to have the 8 speeds work with a wide variety of engines from LS, 2JZ to Barra and more….

We also have available adapters to convert the Jeep eco-diesel transmission to 2wd

These have been tried and tested for alignment and power. These are for 8hp45,50,70,75,76. If you would like to know more get in touch with Andrew. We will have a a full list and a price list coming shortly.

Yesterday was a bittersweet moment where our time at 76 Mort Street had officially concluded after 24 years of working and a childhood spent growing up there.

Now we venture to our new location 74 Mort Street- right next door.

We would like to thank the friends and family that helped us with the move - the extra help made it possible to complete this move.

We look forward to continuing doing what we do in our new location.

Thanks
Team @ Gilroy’s Race Transmissions

Mr Goleby took the new work car for a spin on the weekend. We love these 8 speeds and so thankful to be working with the guys that are just as passionate about them as us. Thanks to Goleby's Parts for their years of support
