Hey guys, I had lost 3rd and 4th on my GSX, so I paid quite a bit for a "used rebuilt 5-sp with only 10k on it" that I installed to find that reverse was f*cked. Now I am having to try and get my money back through the seller, PayPal or my credit card. Anyway, I now have 2 bad transmissions, one with a good reverse and the other with good 1st-5th. Is it hard breaking these open and fixing? Would it be easier/cheaper to fix the 3rd/4th shift fork or replacing the Reverse gear? Thanks
