Kickdown linkage leak

‘67 XR7 seems to have a slight leak from the kickdown linkage mechanism on the driver side of the C4 automatic transmission after a recent change of the filter and fluid. Ideas? Is there a bushing that needs to be replaced? Thanks

There is a seal and a bushing fo that matter but my limited experience with a c-4 is that you are over full on trans fluid . The old 68 we had required about 30 miles of driving to get to the check fluid when warm status…..otherwise it would puke fluid out the vent and all over the exhaust !!

Ended up running it about 1.5 qt low when cold

Thanks, hopefully that’s the problem and not the seal.
