AMS Performance and ShepTrans have had a long relationship that extends far beyond the business world. John Shepherd has been an asset to AMS since our company started over 10 years ago. His services have helped support our EVO and ALPHA GT-R programs and we could not be happier. It's safe to say the records and numbers we have set would not have happened without Sheptrans in our gearbox.

Today, John sent me a pic of a bunch of GR6's at the shop (22 in total) that he is working on. John is a pretty humble person so you wont see him touting his services very often on here. Here at AMS he is quite simply our ONLY choice for GT-R and EVO transmission work. His dedication and passion for his trade has enabled him to do groundbreaking things with GT-R and EVO transmissions. When using ShepTrans you are not just going to another Dodson pro dealer but a dealer that is at the forefront of engineering and enhancing the GT-R GR6 transmission.

If anyone is interested in getting transmission work done we highly recommend you look no further than John Shepherd and ShepTrans.com for all your GT-R GR6 needs.

22 transmissions cant be wrong

What are the approximate costs for doing clips, seals and a first gear upgrade?

this is tangential, but is there any room for weight reduction/geometric restrengthening where GR6 development stands today? just very curious here as the GR6 performs beautifully but really is a hefty piece.

He just finished mine and it should be on the way back now! Thanks John! You did an awesome job on my DSM tranny and I have no doubt this one will be just as great!

I can vouch for Shep.
Had my evo t-case and gearbox upgraded by him and they worked like a charm.

took the abuse of many 6500rpm launches and 700+whp!

Thanks for the kind words guys. We stay pretty quiet about things but we are constantly trying new ideas. With the amount of trannies we have done (over 100 ) it allows us to really understand what these trannies need to survive. Ok now back to work
