Just had to throw a Shout out to Gordon. I am having issues with my TKO600, it just doesnt want to down shift into 2nd without alot of muscle. Gordon has always answered his phone when I call with questions, always backed his parts, and now helping me with trading in my TKO and picking up one of his T5s. If there is anyone out there that is building one of these or planing to build one and you need great parts and great service....Give this vender a chance, you wont be sorry. Thanks again Gordon for putting up with all my phone calls, Love you Brother!!! I will be in touch soon.
