ATRA — the Automatic Transmission Rebuilders Association — is an international trade association for the professional automatic transmission repair industry.
With members across the US and Canada, ATRA’s network of automatic transmission repair professionals can offer you repair and warranty coverage anywhere you’re likely to drive. Because, wherever you go — from coast to coast — there’s always an ATRA member nearby.

With nearly 2000 members, ATRA is larger than every automatic transmission repair chain combined… nearly three times the size of the largest chain in the US. Which means that no chain can provide better warranty coverage than ATRA’s network of professional service centers.

Every ATRA member must adhere to ATRA’s Code of Ethics… ATRA’s standards for providing honest, professional service. So, when you take your car to an ATRA member, you’re assured of polite, professional service, at an honest price.
And not just automatic transmission repair: most ATRA members also provide diagnostic and repair service for manual transmissions, clutches, differentials, drive shafts, drive axles, and transfer cases. Which all boils down to one inescapable conclusion: If your car starts but does not move, you need to call your nearby ATRA member…right away!

ATRA: Always nearby, always ready… your friend-in-the-business for automatic transmission repair.

AND FINALLY...
WE PLEDGE THAT SUCH TRANSMISSION ASSEMBLIES AS WE REPRESENT TO THE CONSUMING PUBLIC AND TO OTHER MEMBERS AS BEING-"REBUILT"-ACCORDING TO THE SPECIFICATIONS OF THE ATRA "BY-LAWS" will be ONLY THOSE UNITS which have been re-processed according to the standards outlined in the ATRA BY-LAWS, and as follows:
