I bought my Integra about 6 months ago and was told that it had a gsr tranny on it. I am currently re-building it because of a 1st to 2nd grind. The case has no markings what so ever. I was probably going to buy a new 1st and second assembly, but are these the same on all the gsr trannies? Or if I get a synchro set are the the same for all gsr trannies? Just want to make sure I don't get shafted when I buy some new parts.
