i'm not sure how much a shift fork would cost, but i just recently tore my G52 tranny apart using my factory service manual and it was a breeze. took it apart, rebuilt it and put it back together in 3 or 4 days. they're really simple and as long as you follow the FSM word for word and remember where all the little balls and stuff go, you'll be okay. i think marlin my make some shift forks for the R-series of trannies.
