Just wanted to give you my honest opinion on Calimer transmissions. I bought a stage 3 23 spline Mt82 from him and got it once I installed it it started leaking oil like bad enough to get on my exhaust. Was told the tailshaft seal was probably not installed correctly so they sent me out another one that I would have to change out but before i could do that the input shaft broke on it. And this was on the street not at the track. The customer service talking to Allen was something in it's own. He seemed like a really nice guy when i originally told him about the problem then changed to being really rude once he had the transmission in his possession. Said there was nothing he could do that he sent out a good transmission and got back a broken one. So now i have to pay another $1440 to get it fixed again granted he is going to now install a 26 spline input shaft. I would recommend staying away from Calimer transmission. Or maybe I just had bad luck and a bad experience with them
