Prior to putting the WEVO unit in how did it shift? If it shifted fine then it is an adjustment issue.
You have to adjust for left right (counter cw/cw) on the coupler and also for for and aft.
When going to a WEVO or Rennshifter the depth of the shift (for/ aft) seems to be more critical.
On my Rennshift unit it would actually stick in a gear (2nd) and not want to come out...I adjusted the coupler a tad (very small movements) so it would not go into that gear as deeply.
No issues after that.
If you had shifting issues prior to the WEVO it will just make them more pronounced.
