904 kicking out of gear

Hi,
I wanted to get some pros input on my problem. I recently installed a factory console in my duster. I fabricated some of the linkage going to the gear selector on the tranny. It works great except when i really step on it. It will kick out of gear if I really step on it. Do you think my fabricated linkage is being hit by the kickdown linkage? If so - I think I am just going to try and find some factory linkage.
Thanks!
