Another tr bad experience for someone. I have a customer call that bought a "Mint B16" hydro tranny he had it installed and I think you know the rest of the story. It grinds 2nd at 4k and higher and grinds 3rd at 3k and higher. He brings to me to rebuild it and I test drive the car and inform him that it isn't a b16 its a gsr. Well I pull it apart to rebuild and we have a few gears that are damaged but, luckily I have a parts tranny (hydro b16) laying around that we get the gear set out of. Now he is running a true B16 and it don't grind any gears..... Another satisfied customer.
