What Transmission do I have?
Hey all, I bought an all original 85 Z28 last week from the original owner. The car has the original lg4 305 mated to the original 5 speed. I have all the original paper work (including the Window Sticker with the RPO codes) I'm not sure if the transmission is a BW T5 because on paper, my transmission RPO code is MM5 (which denotes " merchandised trans, man 5 speed provisions"), while the RPO code for the BW T5 is MK6.
I am extremely confused! Please help!
Thanks,
Joey

Re: What Transmission do I have?
Kevin, thank you so much for clearing up my problem. What is the difference between the World Class T5 and Nonworld Class?
